PSYC 2410 Lecture Notes - Lecture 4: Occipital Lobe, Multipolar Neuron, Parietal Lobe
Document Summary
Contains the cerebral cortex (layer of issue covering the cerebral hemispheres) About 90% of cerebral cortex is neocortex (six layered cortex of relaively recent evoluion) Variaion in the size of the layers of the cortex based on their funcion. The hippocampus is not neocortex (located at edge of cerebral cortex) Two types of corical neurons: pyramidal cells large mulipolar neuron with one big dendrite and one very long axon, stellate cells small interneurons with short axons or no axons. Hemispheres are connected by the corpus callosum (largest cerebral commissure) necessary for the interhemispheric transfer of informaion. Four lobes: frontal lobe, parietal lobe, occipital lobe, and temporal lobe. Limbic system involved in the regulaion of moivated behaviours, emoions, memory, and learning (the 4 fs) Includes the amygdala, hippocampus, fornix, cingulate cortes, septum, and mammillary bodies. Basal ganglia involved in voluntary motor responses and reward.
