PSY 201 Lecture Notes - Lecture 8: Mesolimbic Pathway, Frontal Lobe, Endocrine System
Document Summary
Cerebellum: major part of our ability to maintain balance and motor coordination, typically does not develop well in autism. Substantia nigra: voluntary motor system: part of parkinsons disease. Sensory structures: reflexes associated with vision and hearing: adjusting pupil size, maintaining static visual field. Pain: our mood can effect pain: if you are excited you will not feel as much pain. The forebrain: subcortical structures (2 of each, one on right, one on left) Thalamus: sensory relay center, for all except sense of smell make a direct connection with the thalamus. Synapse: stop and form a synapse loses reaction time. Why do these sensory signals go through the thalamus: consciousness. Has big circuits with cerebral cortex: learning and memory. Basal ganglia: cluster of cell bodies, initiation of voluntary movement, also damaged in parkinson"s disease, check point for deciding to move, basal ganglia can be misfiring in ocd.
