PSY 2502 Lecture Notes - Lecture 1: Prefrontal Cortex, Causal Inference, Diffusion Mri
Document Summary
Three types of cortex: motor, sensory, association: Homunculus: visual representation of the use in correlation to brain mapping. Neurons are mapped out where certain neruons in somatosensory region relate to different places on the body. Combining classification systems: there can be more than one way to name/classify region. Two hemispheres: ideal the left hemi is specialized for some cognitive function that the right isn"t. Left hemisphere associated with language: differences in the two hemispheres. Information coming into the body can cross right at the spinal cord or crosses over at the brain. Either way inputs will cross over from one side of the body to the other side of the brain. Outputs leaving the brain will cross over to the opposite side of the body (crosses at medulla) Everything in the right visual field will go to the left visual cortex. Everything in the left visual field will go to the right: wada test visual cortex.
