PSYC 1001 1st Edition Lecture 15 Outline of Last Lecture I. Neuron Messages a. ReuptakeII. Integrating Signals III. Neurotransmitters and Behaviors IV. Acetylcholine Outline of Current Lecture I. Dopaminea. SchizophreniaII. Serotonina. SSRIIII. EndorphinsIV. Organization of the Nervous System a. NervesCurrent LectureI. Dopaminea. Involved in voluntary movement (along with a ton of other things).i. Low in Parkinson’s Disease1. Leva-dopa (L-dopa): Gets past the blood/brain barrier so this is theonly dopamine substance to actually be able to get to the brain.b. Schizophreniai. This is because of too much dopamine in the brain.c. Involved with rewards.i. Cocaine blocks the reuptake of dopamine.1. So, an agonist increases the effects of dopamine.II. Serotonina. Effects:i. Moodii. Hungeriii. Sleepiv. Arousal1. These are all affected with depression.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.b. Prozac is a Selective Serotonin Reuptake Inhibitor (SSRI).i. So, an agonist of serotonin. III. Endorphinsa. Endogenous Morphinei. Within the origin.b. Reduces pain and associated with pleasure.c. Antagonist of this is naloxone which blocks the effect of endorphins.i. Decreases the effects of opiates (ex.: heroine)IV. Organization of the Nervous System:a. Peripheral Nervous System: Sensory and motor neurons that connect the central nervous system to the rest of the body.i. Nerves: Bundles of axons routed together through peripheral nervous system.b. Somatic Nervous System: Controls the body’s skeletal muscles.i. Carries information through nerves to carry out ‘voluntary’ movement throughout the body.ii. Carries information to the brain about the current state of the muscles.1. E.g.: Where the information is going in the body (location) and what its function
