The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have a brain; diffuse or localised nerve nets are present instead. The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body. In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons. These neurons communicate with one another by means of long protoplasmic fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells.
Physiologically, the function of the brain is to exert centralized control over the other organs of the body. The brain acts on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain.

How Does the Brain Work? - Human Cognition | PSYCHOLOGY & BRAIN SCIENCE The Brain's Inner Workings - HUMAN COGNITION - National Institutes of Health Video from the National Institute of Mental Health (NIMH) - this video narrated by Tom Bosley looks at the neurological basis of higher brain function. Learn how different human behaviors and functions can be isolated to specific areas of the brain, and how with the help of imaging techniques like MRI we can visualize brain activity in a way that gives insight into how the brain functions and allows scientists to develop treatment methods for various mental illnesses in the future.

The cerebrum enables sensory perception and controls voluntary motor actions. - The cerebellum (SER-eh-BEL-um) – the cerebellum lies inferior to the cerebrum at the back of the head. It is mostly involved in coordination of movement and fine tuning of motor activities. - The brainstem - the brainstem is located at the base of the brai...

In this teaching video, Suzanne Stensaas, Ph.D., Professor of Neurobiology and Anatomy at the University of Utah School of Medicine, demonstrates the properties and anatomy of an unfixed brain. WARNING: The video contains graphic images, a human brain from a recent autopsy. Background noise is unrelated to this brain or the deceased. There are two purposes for this video: 1) to stress the vulnerability of the brain to highlight the importance of wearing helmets, seat belts, and taking care of this very precious tissue, and 2) to use as a teaching aid for students who only have access to fixed tissue, models, and pictures.

Read your free e-book: http://copydl.space/mebk/50/en/B000OT7V5Y/book This volume reflects the pressure to develop useful models and methodologies to study executive behaviour the ability to update information in working memory in order to control selective attention to formulate plans of action and to monitor their efficient execution. Many models are based on the concept of a single "central executive" that manges these functions; others propose a number of independent "working memory systems" that each serve one task or activity but not others.; This book is a collection of essays by active researchers who discuss their own work on the definition of "executive" or "controlled" behaviours, and on the relation of these behaviours to specific areas of the frontal cortex. The papers are par...

Noah Wall's incredible journey is going to be made into a documentary The true story of a boy born with no brain is to be shown as a documentary on Channel 5. Brave disabled lad Noah Wall is to be the subject of a new documentary titled The Boy With No Brain which will air Tuesday 12 October. Little Noah was born with just two per cent brain function and spina bifida in 2012, but he has stunned medical professionals by surviving this long and now his family will document his progress. The four-year-old's condition left him paralysed from the chest down and in need of a permanent head drain to keep fluid off his brain, but miraculously scans showed his brain is now almost fully functional and has been growing. Doctors at Newcastle’s Great North Children’s Hospital had never expected su...

According to a new study, women who drink two to three cups of coffee a day may have better brain functioning later in their lives. To conduct the study, researchers from University of Wisconsin-Milwaukee looked into the benefits of caffeine consumption on brain function in postmenopausal women. They then recruited 6,467 women from the Women’s Health Initiative Memory Study, an ongoing randomized controlled clinical trial testing postmenopausal hormone therapy. Each participant’s cognitive function was assessed all the way back from 2007, while caffeine intake was measured at the start of the study two additional times, through self-reported questionnaires. http://fusion.net/story/354421/caffeine-coffee-dementia-study/ http://www.wochit.com This video was produced by YT Wochit News using ...

How Does The Brain Work | Science documentary The human brain has the same general structure as the brains of other mammals, but is larger than any other in relation to body size. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin, and three times as large as the brain of a chimpanzee. Much of the expansion comes from the part of the brain called the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The portion of the cerebral cortex devoted to vision is also greatly enlarged in humans. ...
(Visit: http://www.uctv.tv/) Findings reveal that: 1) children with autism show a distinctly anomalous pattern of motor learning, with a bias towards reliance on proprioceptive, rather than visual, feedback; 2) this anomalous pattern of motor learning is associated with the severity of motor skill deficits, as well as the social skill deficits that define the core features of autism; and 3) children with autism show decreased intrinsic visual-motor connectivity in functional MRI that is associated with the core symptoms exhibited by children with autism. Evidence of anomalous motor learning in autism and its association with motor skill impairments and deficits in social and communicative skills will be presented, as will convergent data from neuroimaging techniques, revealing that these m...
Rhonda Patrick, Ph.D. discusses how diet can affect DNA damage, a well-known initiator of cancer and dietary changes that can lower DNA damage. She talks about her recent publications on how vitamin D controls serotonin and how this affects brain function and behavior. She also explores the intersection between genetics and environment: how your diet, micronutrients, exercise, and sleep can change the expression of your genes, how this has profound effects on the way your body functions and ages, and how these effects can be passed on to your grandchildren.

NCCAM Integrative Medicine Research Lecture Aniruddh (Ani) Patel, Ph.D., is an Associate Professor in the Department of Psychology at Tufts University. Dr. Patel's research focuses on how the brain processes music and language, focusing on what the similarities and differences between the two reveal about each other and about the brain itself. He has pursued this topic with a variety of techniques, including neuroimaging, theoretical analyses, acoustic research, and comparative studies of nonhuman animals. Dr. Patel has published more than 50 research articles and a scholarly book (Music, Language, and the Brain, 2008, Oxford Univ. Press). Dr. Patel was awarded the 2009 Music Has Power award from the Institute for Music and Neurologic Function in New York City. In this lecture, Dr. Patel...

Using the measurements available, early Exercise Science focused on cardiorespiratory training and its ability to improve function and wellness in human beings. As measures have become more sensitive, resistance training has shown to provide similar and sometimes greater benefits than cardiorespiratory training specifically in regards to brain health. This presentation will examine the research conclusions and clinical outcomes from resistance training's affect on brain structure and brain function.
