Drug addiction affects the brain reward system by increasing the activity of the nervous circuitry that increases activity in pleasure motivation and learning.
A) True B) False
Homework Answers
FALSE
Drug addiction involves loss of control of brain activities.
Addiction changes the brain by subverting the way it register
pleasure and to lose control over the activities such as learning
and motivation. Simply, drug addiction decrease the activity in
pleasure motivation and learning.

The Brain on Mind Altering Drugs Psychoactive drugs alter brain function by acting at synapses in the brain, where they may mimic, enhance, or block the effects of natural signaling molecules (neurotransmitters). The neurotransmitter dopamine plays a particularly important role in creating the dependency aspect of both drug and behavioral addictions. Natural behaviors which enhance survival and/or reproduction, such as eating or engaging in sex, result in a surge of dopamine. Normally, this response helps individuals learn to repeat beneficial...

The autonomic nervous system can change the rate of the heart by: (could have multiple correct answers) a) beta1 adrenergic receptor activation. Increases in cAMP lead to increased amounts of Na+ influx (though If channels) and Ca2+ influx of the pacemaker cells. This increases the frequency of APs of the pacemaker, and increases the rate of contraction. b) beta2 adrenergic receptor activation. Increases in cAMP lead to increased amounts of Na+ influx (though If channels) and Ca2+ influx of the...
