PSYCH 345 Lecture Notes - Lecture 4: List Of Thalamic Nuclei, Motor Cortex, White Matter
Document Summary
Brain maps: orderly representation of a sensory surface onto the surface of the cortex, classification and definition of cortical regions, different types of maps for viewing specific cell types and structures, cytoarchitectonic map = architecture of cells. Layer 3: association cortex and commissures (intra and inter hemispheric) Layer 5: goes to brainstem and spinal cord (cortico-spinal) Layer 6: signals to the thalamus (cortico-thalamic: layer 4, receiving signals from other layers, input from thalamus might be thicker, differences between motor and sensory cortex, motor cortex. Makes sense, layers 5 and 6 are in charge of sending signals, so they control outputs that are meant for controlling movement/behavior: sensory cortex. This makes sense, all sensory inputs go to the sensory cortex, the receiving layer needs to be bigger to handle all the sensory input. From the thalamus to other areas of the cortex. Sensory input gets processed in the thalamus, then relayed to different cortical primary areas.
