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 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.

comment How do ligands bind to and release from receptors?
This is the text used in the course. It's gone up a lot in price, but it's very helpful.

Look for the Coursera course "Drugs and the Brain" and see when it's offered next. It touches on a lot of these issues and more, and I think you would find it fascinating. Meanwhile, I'll see if I can answer some of this a bit later.
