Sir Charles Scott Sherrington is one of my science heroes, so I'm featuring him on my cogsci profile. He is often credited with coining the word "synapse."

comment Can one become less neurotic?
It depends on how you measure "neurotic", really.

comment Can a person control their brain's electrical activity?
The P300 response will not be as pronounced, but won't be completely eliminated in the case of "if the user knows that stimulus..." that you cite in the comment. Remember that we analyze these EEG patterns over multiple epochs (short periods of time) and can time-lock them to the stimulus, so we can "line up" the responses and average them.

comment Can a person control their brain's electrical activity?
@Learner It's laid out in the Wikipedia article, but if you have an auditory stimulus that's going "beep, beep, beep, beep", and every few seconds there is a "boop" mixed in, the "boop" is a low-probability stimulus (less likely to occur) and will generate a more pronounced P300 wave. This phenomenon can occur naturally as well if we are surprised by something (a siren on a quiet day, etc.). I don't quite know how such an effect manifests for a visual stimulus, but I imagine that the "oddball" effect is somewhat similar.

This is the text used in the course. It's gone up a lot in price, but it's very helpful.
