Document Summary
Left frontal lo(cid:271)e(cid:894)bro(cid:272)a"s area(cid:895) - expression of speech. Werni(cid:272)ke(cid:859)s aphasia (cid:894) e(cid:272)epti(cid:448)e aphasia(cid:895) ( left temporal lobe) Regardless of modality, sign and speech, recruit wernicke and broca regions. Minimally conscious state - sometimes go in and out of awareness. Locked -in syndrome know everything, but (cid:272)an(cid:859)t communicate or move other than blinking. Eeg measures the activity of 1000s of neurons within the 1-2mm outer surface of the cortex. Checks the voltage from different points of the brain. Zeitgeber: a stimulus that resets the biological clock (e. g. bright light) Transition from wakefulness to the onset of sleep. Defined by waves of 12 to 14hz that occur in burst (sleep spindles) Stages 3 and 4 (sometimes referred to as slow-wave sleep sws) Sleep spindles as in stages 2 occur. Eeg reverts to a low voltage, mixed frequency pattern. The first 4 hours contain more sws, especially stages 3 and 4.
