s we have seen, your brain’s information processing occurs as neurons talk to
other neurons, by sending chemical messengers across the tiny synaptic gaps. Activate Prior Knowledge
A When these neurotransmitter chemicals are supplemented or replaced by drugs,
strange things can happen. (10 minutes) Begin class with
this activity, which asks students
to decide if statements are
true or false. The statements
tap into common beliefs and
misconceptions about psychology.
