Document Summary
Pros: similar structure, less complex, inexpensive=more subjects, more allowed. Cons: communication, ethics, animals cannot follow instructions, not all processes are the same - cerebral cortex. Animals: genetic manipulation, lesion studies (causing damage) Neuroimaging: non-invasive way to see brain (pet,fmri, mri) Electrophysiology: measures electrical activity in brain (eeg) Neurocytology: stains cells to see anatomy and activity of connections. Ventral root: takes info from cns to muscles (efferent) Separated by longitudinal fissure, connected by corpus callosum. Cortex: nerves on outside of brain---nuclei: nerves on inside of brain. Gyrus: top of brain fold------------------sulcus: bottom of brain fold. Midbrain: more advanced ex. movement/reward/arousal/auditory and visual reflexes. Forebrain: human qualities ex. emotion, memory, cognition. Piamater: first thin layer (contains blood vessels) Meningitis: infection of meninges, causes neck stiffness, confusion & low tolerance to light & noise. Ventricles: 4 fluid chambers of brain that cushion brain and flush toxins out. Hydrocephalus: blockage of draining cerebral spinal fluid caused by infection.
