Long-term potentiation is thought to be the molecular event that contributes to learning. Through synaptic plasticity LTP is established between various neurons, allowing for the learning process to occur. This video explains the molecular underpinnings leading up to LTP including both early and late phase changes. The video begins with the action potential and outlines the various stages required to establish synaptic changes. These synaptic changes lead to the formation of a stronger synapse and ultimately a stored memory within the brain.
Long-term potentiation, or LTP, is a process by which connections between neurons become stronger with frequent activation. LTP is thought to be a way in which the brain changes in response to experience, and thus may be an mechanism underlying learning and memory. In this video, I discuss one type of LTP: NMDA-receptor dependent LTP. I outline the mechanism underlying NMDA-receptor LTP and describe how it is thought to strengthen synaptic connections where it occurs.
TRANSCRIPT:
Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss long-term potentiation, or LTP.
LTP is a process by which synaptic connections between neurons become stronger with frequent activation. LTP is thought to be a way in which the brain changes in response to experience, and thus may be an mechanism underlying learning and memory.
There are a number of ways in which LTP can occur. The best-known mechanism involves a glutamate receptor known as the NMDA receptor. In NMDA-receptor dependent LTP, glutamate release first activates a subtype of glutamate receptor known as the AMPA receptor. NMDA receptors are found nearby these AMPA receptors, but are not activated by low levels of glutamate release because the ion channel of an NMDA receptor is blocked by a magnesium ion. If frequent action potentials cause greater stimulation of AMPA receptors, however, this will cause the postsynaptic neuron to depolarize,
which eventually causes the voltage-dependent magnesium blockage of the NMDA receptor to be removed, allowing calcium ions to flow in through the NMDA receptor. This influx of calcium initiates cellular mechanisms that cause more AMPA receptors to be inserted into the neuron’s membrane. The new AMPA receptors are also more responsive to glutamate, and allow more positively charged ions to enter the cell when activated.
Now, the postsynaptic cell is more sensitive to glutamate because it has more receptors to respond to it. Additionally, there are thought to be signals that travel back across the synapse to stimulate greater levels of glutamate release. All of this makes the synapse stronger and more likely to be activated in the future.
This process is also associated with changes in gene transcription in the neuron, which can lead to the production of new receptors or modifications to the structure of the cell. These changes seem to be important for making the increased responsiveness of LTP long-lasting.

The process of learning begins in the cortex. Sensory signals are then transmitted to the hippocampus. If a signal is strong, or repeated, a long-term memory is established and wired back to the cortex for storage. Lesions in the hippocampus impair formation of new memories, but do not affect the older ones.
The brain consists of billions of neurons. Neurons communicate with each other through a synapse. Synaptic connections can change over time, a phenomenon known as synaptic plasticity. Synaptic plasticity follows the “use it or lose it” rule: frequently used synapses are strengthened while rarely used connections are eliminated (synaptic pruning). Synaptic plasticity is believed to underlie the process of learning and memory retention.
High-frequency signals or repeated stimulations STRENGTHEN synaptic connections over time. This is known as long-term potentiation, or LTP, and is thought to be the cellular basis of memory formation. LTP can occur at most excitatory synapses all over the brain, but is best studied at the glutamate synapse of the hippocampus. When a glutamatergic neuron is stimulated, action potentials travel down its axon and trigger the release of glutamate into the synaptic cleft. Glutamate then binds to its receptors on the post-synaptic neuron. The 2 main glutamate receptors that often co-exist in a synapse are AMPA and NMDA receptors. These are ion channels that activate upon binding to glutamate. When the pre-synaptic neuron is stimulated by a WEAK signal, only a small amount of glutamate is released. Although both receptors are bound by the glutamate, only AMPA is activated by weak stimulation. Sodium influx through the AMPA channel results in a SLIGHT DE-polarization of the post-synaptic membrane. The NMDA channel remains closed because its pore is blocked by magnesium ions.
When the pre-synaptic neuron is stimulated by a STRONG or REPEATING signal, a large amount of glutamate is released; the AMPA receptor stays open for a longer time, admitting more sodium into the cell, thus resulting in a GREATER DE-polarization. Increased influx of positive ions EXPELS magnesium from the NMDA channel, which NOW activates, allowing not only sodium but also CALCIUM into the cell. Calcium is the mediator of LTP induction. There are 2 distinct phases of LTP. In the early phase, calcium initiates signaling pathways that activate several protein kinases. These kinases enhance synaptic communication in 2 ways: they phosphorylate the existing AMPA receptors, thereby increasing AMPA conductance to sodium; and help to bring more AMPA receptors from intracellular stores to the post-synaptic membrane. This phase is thought to be the basis of short-term memory, which lasts for several hours. In the late phase, NEW proteins are made and gene expression is activated to further enhance the connection between the 2 neurons. These include newly synthesized AMPA receptors, and expression of other proteins that are involved in the growth of NEW dendritic spines and synaptic connections. The late phase may correlate with formation of long-term memory.

Khan Academy
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
History
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

AMPA receptor
The α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (also known as AMPA receptor, AMPAR, or quisqualate receptor) is a non-NMDA-type ionotropic transmembrane receptor for glutamate that mediates fast synaptic transmission in the central nervous system (CNS). Its name is derived from its ability to be activated by the artificial glutamate analog AMPA. The receptor was first named the "quisqualate receptor" by Watkins and colleagues after a naturally occurring agonist quisqualate and was only later given the label "AMPA receptor" after the selective agonist developed by Tage Honore and colleagues at the Royal Danish School of Pharmacy in Copenhagen. AMPARs are found in many parts of the brain and are the most commonly found receptor in the nervous system. The AMPA receptor GluA2 (GluR2) tetramer was the first glutamate receptor ion channel to be crystallized.
Structure and function
Subunit composition
AMPARs are composed of four types of subunits, designated as GluR1 (GRIA1), GluR2 (GRIA2), GluR3 (GRIA3), and GluR4, alternatively called GluRA-D2 (GRIA4), which combine to form tetramers. Most AMPARs are heterotetrameric, consisting of symmetric 'dimer of dimers' of GluR2 and either GluR1, GluR3 or GluR4. Dimerization starts in the endoplasmic reticulum with the interaction of N-terminal LIVBP domains, then "zips up" through the ligand-binding domain into the transmembrane ion pore.

Long-term potentiation
In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increase in signal transmission between two neurons. The opposite of LTP is long-term depression, which produces a long-lasting decrease in synaptic strength.
It is one of several phenomena underlying synaptic plasticity, the ability of chemical synapses to change their strength. As memories are thought to be encoded by modification of synaptic strength, LTP is widely considered one of the major cellular mechanisms that underlies learning and memory.
LTP was discovered in the rabbit hippocampus by Terje Lømo in 1966 and has remained a popular subject of research since. Many modern LTP studies seek to better understand its basic biology, while others aim to draw a causal link between LTP and behavioral learning. Still others try to develop methods, pharmacologic or otherwise, of enhancing LTP to improve learning and memory. LTP is also a subject of clinical research, for example, in the areas of Alzheimer's disease and addiction medicine.

NMDA receptor
The N-methyl-D-aspartate receptor (also known as the NMDA receptor or NMDAR), is a glutamate receptor and ion channel protein found in nerve cells. It is activated when glutamate and glycine (or D-serine) bind to it, and when activated it allows positively charged ions to flow through the cell membrane. The NMDA receptor is very important for controlling synaptic plasticity and memory function.
The NMDAR is a specific type of ionotropic glutamate receptor. The NMDA receptor is named this because the agonist molecule N-methyl-D-aspartate (NMDA) binds selectively to it, and not to other glutamate receptors. Activation of NMDA receptors results in the opening of an ion channel that is nonselective to cations with a reversal potential near 0 mV. A property of the NMDA receptor is its voltage-dependent activation, a result of ion channel block by extracellular Mg2+ & Zn2+ ions. This allows the flow of Na+ and small amounts of Ca2+ ions into the cell and K+ out of the cell to be voltage-dependent.

This video explains the molecular underpinnings leading up to LTP including both early and late phase changes. The video begins with the action potential and outlines the various stages required to establish synaptic changes. These synaptic changes lead to the formation of a stronger synapse and ultimately a stored memory within the brain.

Long-term potentiation, or LTP, is a process by which connections between neurons become stronger with frequent activation. LTP is thought to be a way in which the brain changes in response to experience, and thus may be an mechanism underlying learning and memory. In this video, I discuss one type of LTP: NMDA-receptor dependent LTP. I outline the mechanism underlying NMDA-receptor LTP and describe how it is thought to strengthen synaptic connections where it occurs.
TRANSCRIPT:
Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss long-term potentiation, or LTP.
LTP is a process by which synaptic connections between neurons become stronger with frequent activation. LTP is thought to be a way in which the brain changes in response to experience, and thus may be an mechanism underlying learning and memory.
There are a number of ways in which LTP can occur. The best-known mechanism involves a glutamate receptor known as the NMDA receptor. In NMDA-receptor dependent LTP, glutamate release first activates a subtype of glutamate receptor known as the AMPA receptor. NMDA receptors are found nearby these AMPA receptors, but are not activated by low levels of glutamate release because the ion channel of an NMDA receptor is blocked by a magnesium ion. If frequent action potentials cause greater stimulation of AMPA receptors, however, this will cause the postsynaptic neuron to depolarize,
which eventually causes the voltage-dependent magnesium blockage of the NMDA receptor to be removed, allowing calcium ions to flow in through the NMDA receptor. This influx of calcium initiates cellular mechanisms that cause more AMPA receptors to be inserted into the neuron’s membrane. The new AMPA receptors are also more responsive to glutamate, and allow more positively charged ions to enter the cell when activated.
Now, the postsynaptic cell is more sensitive to glutamate because it has more receptors to respond to it. Additionally, there are thought to be signals that travel back across the synapse to stimulate greater levels of glutamate release. All of this makes the synapse stronger and more likely to be activated in the future.
This process is also associated with changes in gene transcription in the neuron, which can lead to the production of new receptors or modifications to the structure of the cell. These changes seem to be important for making the increased responsiveness of LTP long-lasting.

The process of learning begins in the cortex. Sensory signals are then transmitted to the hippocampus. If a signal is strong, or repeated, a long-term memory is established and wired back to the cortex for storage. Lesions in the hippocampus impair formation of new memories, but do not affect the older ones.
The brain consists of billions of neurons. Neurons communicate with each other through a synapse. Synaptic connections can change over time, a phenomenon known as synaptic plasticity. Synaptic plasticity follows the “use it or lose it” rule: frequently used synapses are strengthened while rarely used connections are eliminated (synaptic pruning). Synaptic plasticity is believed to underlie the process of learning and memory retention.
High-frequency signals or repeated stimulations STRENGTHEN synaptic connections over time. This is known as long-term potentiation, or LTP, and is thought to be the cellular basis of memory formation. LTP can occur at most excitatory synapses all over the brain, but is best studied at the glutamate synapse of the hippocampus. When a glutamatergic neuron is stimulated, action potentials travel down its axon and trigger the release of glutamate into the synaptic cleft. Glutamate then binds to its receptors on the post-synaptic neuron. The 2 main glutamate receptors that often co-exist in a synapse are AMPA and NMDA receptors. These are ion channels that activate upon binding to glutamate. When the pre-synaptic neuron is stimulated by a WEAK signal, only a small amount of glutamate is released. Although both receptors are bound by the glutamate, only AMPA is activated by weak stimulation. Sodium influx through the AMPA channel results in a SLIGHT DE-polarization of the post-synaptic membrane. The NMDA channel remains closed because its pore is blocked by magnesium ions.
When the pre-synaptic neuron is stimulated by a STRONG or REPEATING signal, a large amount of glutamate is released; the AMPA receptor stays open for a longer time, admitting more sodium into the cell, thus resulting in a GREATER DE-polarization. Increased influx of positive ions EXPELS magnesium from the NMDA channel, which NOW activates, allowing not only sodium but also CALCIUM into the cell. Calcium is the mediator of LTP induction. There are 2 distinct phases of LTP. In the early phase, calcium initiates signaling pathways that activate several protein kinases. These kinases enhance synaptic communication in 2 ways: they phosphorylate the existing AMPA receptors, thereby increasing AMPA conductance to sodium; and help to bring more AMPA receptors from intracellular stores to the post-synaptic membrane. This phase is thought to be the basis of short-term memory, which lasts for several hours. In the late phase, NEW proteins are made and gene expression is activated to further enhance the connection between the 2 neurons. These include newly synthesized AMPA receptors, and expression of other proteins that are involved in the growth of NEW dendritic spines and synaptic connections. The late phase may correlate with formation of long-term memory.

A discussion of long term potentiation in the context of learning and memory.
The explanation of classical conditioning is simplified and each dendrite labelled would represent many dendrites making up the circuits associated with each stimulus and behavior. Also, although LTP has been heavily studied in the hippocampus, classical conditioning associated with an audible tone would take place in the lateral amygdala.
