An evoked potential (or "evoked response") is an electrical potential recorded from the nervous system of a human or other animal following presentation of a stimulus, as distinct from spontaneous potentials as detected by electroencephalography (EEG) or electromyography (EMG).

Evoked potential amplitudes tend to be low, ranging from less than a microvolt to several microvolts, compared to tens of microvolts for EEG, millivolts for EMG, and often close to a volt for ECG. To resolve these low-amplitude potentials against the background of ongoing EEG, ECG, EMG, and other biological signals and ambient noise, signal averaging is usually required. The signal is time-locked to the stimulus and most of the noise occurs randomly, allowing the noise to be averaged out with averaging of repeated responses.

Signals can be recorded from cerebral cortex, brain stem, spinal cord and peripheral nerves. Usually the term "evoked potential" is reserved for responses involving either recording from, or stimulation of, central nervous system structures. Thus evoked compound motor action potentials (CMAP) or sensory nerve action potentials (SNAP) as used in nerve conduction studies (NCS) are generally not thought of as evoked potentials, though they do meet the above definition.

The Angles is a modern English term for a Germanic people who took their name from the ancestral cultural region of Angeln, a district located in Schleswig-Holstein, Germany. The Angles were one of the main groups that settled in Britain in the post-Roman period, founding several of the kingdoms of Anglo-Saxon England, and their name is the root of the name "England".

The name of the Angles is first recorded in Latinized form, as Anglii, in the Germania of Tacitus. The name is usually derived from a toponym, Angeln, from a Germanic word *anguz meaning "narrow" (of an estuary) or "angular" (of the shape of the Jutland peninsula).

Gregory the Great in an epistle simplified the Latinized name Anglii to Angli, the latter form developing into the preferred form of the word. The country remained Anglia in Latin. King Alfred's (Alfred the Great) translation of Orosius' history of the world uses Angelcynn (-kin) to describe England and the English people; Bede used Angelfolc (-folk); there are also such forms as Engel, Englan (the people), Englaland, and Englisc, all showing i-mutation.

He also appears as Bra's Jeff in Donald McLeary and Sanjeev Kohli's Sony Award winning BBC Radio 4 sitcom Fags, Mags and Bags.

McNicoll has co written several plays for stage and radio.

In 2001, his play for BBC Radio 4, There Are Such Things, about the life and career of horror movie legend, Bela Lugosi, won the Hamilton Deane Award for best dramatic presentation from the Dracula Society. Prior to that, in 1997, as writer and actor, McNicoll was a co-recipient of The Herald Angel Award for the stage play Empty Jesters. In 2005, Scottish cultural magazine the List nominated him at number 69 in their Hot 100 List which celebrated those who had made the biggest cultural impact in Scotland that year. In 2007, he starred as Sammy Fox in the critically acclaimed BBC TV comedy series Legit, which was nominated for a Rose D'or.
