PSYA01H3 Lecture Notes - Lecture 9: Parietal Lobe, Proprioception, Visual Cortex
Document Summary
Lecture 9 notes - review of neuron process: They send the firing signals by releasing chemicals that produce a negative or positive effect. There is always the synaptic cleft (between the presynaptic neuron and the postsynaptic neuron) The chemicals are released into that cleft (chemicals = neurotransmitters) The neurons decide to fire based on the more positive or negative charges. External drugs can influence the brain in the synaptic cleft (it simulates neurotransmitters and tricks the neurons to fire) Cerebral cortex (wrinkly stuff/) -> high level processing, perception, controlled motor activities. Our skull has expanded in the front because our frontal lobe is more developed. Fissures and sulci in the brain (divided areas) All lobes are divided into primary cortex and association cortex. Cat in the hat example -> association cortex that takes raw stimulation and interprets it based on things ur brain has seen/knows.
