Neuroscience is a fascinating and fairly recent area of study. For those of you who wish to learn more, I have discovered this helpful resource. Brain Facts dot org has a free primer download on the brain and nervous system (see below).
Too many of us are currently in possession of brains and nervous systems that are more or less immediately and adversely affected from exposures to toxic chemicals, some molds, wireless and other environmental contaminants.
As one of these people, I have been fascinated by the changes that occur in my brain at times, (despite the fact that most of the changes are highly disruptive and disabling instead of pleasant) and so I am really trying to learn more about these processes and what might be happening.
