Document Summary
Anterior = rostral, posterior = caudal, dorsal = superior, ventral = inferior. Spinal cord, cerebellum, cerebrum, septum peucidum, diencephalon (thalamus/hypothalamus), brainstem (midbrain, pons, medulla oblongata) Sulcus = big inny-wrinkles, gyrus = little bumpy thing. Interhemispheric fissure (= big sulcus) divides brain into two hemispheres, right down to corpus callosum. Sylvian fissure/insula (horizontal, separates temporal from parietal and frontal lobes). Superior, middle and inferior temporal gyrus. superior and inferior temporal sulci in the middle. Refer to slides for various sulci and gyri. Grey matter = folded sheets containing dendrites and cell bodies. White matter = axons (white because of myelin sheath) Cytoarchitectonics: study the changes in the 6 layers (thickness and density) across the cortex. Where the changes occur, identify borders (why are there 6 layers?) We care about this because there is a relation between function and appearance. We want to develop an observer independent method to analyze grey level index (gli)
