Chapter 3 Spinal cord Neural circuit Reflex arc: proprioceptor Dorsal horns propreseptor Sensory neuron Interneuron Nociceptor motor neuron Ketamine glutamate antagonism glutamate binds to receptors when inhaled to spinal cord perient can't get pain signalering central pattern generator Ventral horns Brain stem medulla cranial nerves controls: Breathing pattern generator Firing as specific care so you dont have to think about it Heart rate Digestion PONS Dorsolateral pons: Located in the middle of descending motor pathway protective Raphe nucleus serotonin & norepinepherine released when from acting out dreams REM sleep: rapid eye movement - dreams Hypothalamus suprachiasmatic nucleus La receives input from optic nerves about amount of light available circadian rhythm Disease / damage: sleep apnea: stop breathing during REM sleep (destroying neurons in dorsolarens pons) REM w/o aronia NON REM DREAMS REM DREAM short two seconds Longer ismin thinking of different spines on dendrites erupt possibilities Le NMDA receptors Cerebellum involved in learning new motor skills Controls the force and range of motion Adjusts movements (corrects for errors) as the movement occurs plays a role in organization of speech (over use in stuttering) Damage of cerebellum movements are disrupted NOT abolished cerebellar action tremor only if mistake is made during a movement Hypotonia impaired skill earning Astana avasia can't compensate for gravity lake drunk movements) Ipsitatem mirscie Chapter 3 ATAXIA: a lack of muscle control during voluntary movements → persistent ataxia usually results from damage to cerebellum causes: alcohol abuse, stroke, tumor, cerebral palsy and multiple sclerosis, inherited gene Cerebellar Nystagmus - Horizontal more indicative of cerebellum damage. Dysarthria - missing part of word (in buttercup) force and range (intention/action tremor and past pointing) Rebound Diencephalon: thalamus relay center for nociceptor/pain Parietal Lobes hypothalamus motor motor control somatosensory cortex mammillary bodies sensors processing cortex (parietal) Reconnect Hypothalamus control of endocrine system Contains a nucleus that commits behavior you have an area that controls autonomic nervous system lateral hypothalamus arousal center for eating turned on, you will eat nucleus for each emotion testing → Rage - autonomic primitive emotional behavior Endocrine response
