Summary
This document provides information on the brain's structure and components, including the ventricles, cerebrospinal fluid, and different brain divisions (forebrain, etc.). It highlights the functions of different brain regions and the roles of the corpus callosum and other subcortical regions.

- Third ventricle - connects to cerebral aquaduct to fourth ventricle near Cerebellum - Cerebral Spinal fluid (CSF): - Lateral - third - fourth - Subarachoid space - absorbed into blood supply - Choroid plexus - manufactures CSF extending into ventricles - Brain Divisions: "circuit" - brain region - Forebrain: - Telencephalon (end brain) - covered by cerebral cortex - Lobes - frontal, parietal, temporal , occipital - Convulsions - sulci (small grooves) and fissures (large grooves) and gyri (bulges between above) - Cortex - made up of glia, cell bodies, dendrites, and axons - Glia - Supportive and nourishing cells - Myelin - white matter - Primary motor cortex - anterior to central sulcus - Primary visual cortex - back of brain at colcorine fissure - Primary auditory cortex - sides of brain above lateral fissure - Primary somatosensory cortex - caudal of central sulcus - Prefrontal cortex - formulating plans + strategies - A) mirror neurons - "empathy" frontal, parietal regions, Somatosensory cortex, etc. - Telencephalon also includes limbic system + basal ganglia - Subcortical Regions: Lateralization - Left - analysis of information, language, communication, writing, speech, etc. - Right - complex activities - map reading, drawing - Corpus Callosum - Connects left/right, includes the anterior and posterior commissures and massa intermedia
