BY 108 Chapter Notes - Chapter 20: Inferior Temporal Gyrus, Tau Protein, Reticular Formation
Document Summary
Sleep/arousal - reticular formation in brain stem controls consciousness less stimuli >> less active reticular formation >> easier to sleep. Sleep = active process, not lack of consciousness. Electroencephalogram (eeg) - records electrical activity in the brain. Alpha waves - 8-13 hertz, found in relaxed/awake people. Beta waves - 13-30 hertz, found in alert people theta/delta waves - found in sleeping people. Rem sleep - rapid eye mov"t sleep. Eeg like that of relaxed, awake person. Advertising inread invented by teads language/spatial recognition - hemispheres each responsible for different jobs left hemisphere = dominant language area for 9/10 of right-handed people, Wernicke"s area - found in parietal lobe between auditory/visual areas. Broca"s area - found near motor cortex controlling the face. Controls motor skills needed for language communication. Aphasias - language disorder where words lack meaning, due to damage in. Right hemisphere = nondominant hemisphere, good at spatial reasoning and musical ability.
