TERM 1 Cerebellum DEFINITION 1 Structure on back of brainstemControls coordinated movements and learned movements TERM 2 Balance DEFINITION 2 Maintains balance and controls eye movement TERM 3 Coordination DEFINITION 3 Connected to motor cortex, receives "motor plan"Afferent input gives current muscle positionFunction with aim, i.e. movement matches motor plan TERM 4 Input to Cortex DEFINITION 4 Allows cortex to know current position and movement Cortex uses this information to plan future movements TERM 5 Brain stem DEFINITION 5 Medulla, pons, midbrainInterface between spinal cord and higher brain centersCranial nerves supply sensory and motor function to head and neckDifferent centers in brain stem control heart rate, breathing TERM 6 Reticular Activating System DEFINITION 6 Neural net, awareness of surroundingsCortical, pain, auditory, visual inputOutput to cortex and thalamus --> All cortexControls consciousness/ sleep TERM 7 Sleep DEFINITION 7 Low frequency activity in hypothalamus & thalamusReason needed is unknown TERM 8 EEG Patterns DEFINITION 8 Slow wave patterns in EEG give slow wave sleep its nameEEG pattern during REM sleep similar to being awake TERM 9 Slow Wave Sleep DEFINITION 9 4 stages, each progressively deeper over about 75 min cycleCircadian rhythm - ^ adenosine -> sleepCaffeine blocks adenosine responseSleep factor: muramyl dipetide --> Strong sleep inducer TERM 10 Rapid Eye Movement DEFINITION 10 (Paradoxical sleep)15 minutes long, at the end of a slow wave sleep cycle Paradoxical sleep --> Hard to awaken, most likely to wake selfHigh visual cortex, low frontal, high memory areas --> dreams illogical
