| A | B |
|---|
| Autonomic Nervous System | Division of peripheral nervous sy, involved in control of visceral functions (smoothmuscles/glands) heart rate, bp, respiration, digestion, sweat) |
| Central Nervous System | spinal cord and brain |
| Somatic Nervous System | Dividon of peripheral nervous s involved in control of skeletal muscles & skin receptors |
| Parasympathetic Nervous System | Division of autonomic nerv. sx., involved in conservation of energy/relaxation. slow heart, lower bp, etc. |
| Sympathetic Nervous System | Dividion of the autonomic nervous sx, involved in emergency reactions. Incr heart rate, pupil dialate. Fight/flight. |
| Spinal Cord | Transmits sensory & motor info to & from brain. Pt. of CNS. Damage can cause quadraplegia, parapeligia, hemiplegia, paresis. |
| Long-Term Potentiation | Changes in str of synapses following hi frequency stimulation of neurons. Found in hippocampal cells, responsible for long term mem. |
| Gate Control Theory | Pain theory proposing that pain impulses can be blocked by competing impulses going to & coming from the brain |
| Closed Head Injury | loss of consciousnes. On recovery, antrograde & retrograde amnesia and other cog sx & chgs in behavior a& motor abilities. Best predictor of recovery: duration of anterograde amnesia. |
| Anterograde Amnesia | Post traumatic loss of memory |
| Retrograde Amnesia | ??? not sure of this one. |
| Structural Brain Imaging Techniques | MRI and CT scan: Id blood clots, tumors and other abnormalities. |
| Functional Brain Imaging Techniques | PET Scan, SPECT and functional MRI, looking @ neural activity: ie, cerebral blood flow. |
| Auditory Localization | Orientation to the dir. of sound. |
| All or None Law | Biological law governing action potential. AP will occur when neuron receives minimal level of stimulation. More stimulation doesn't affect size or speed of AP. |
| Testosterone | Male sex hormone, facilitates copulating response and 2ndary sex characteristics, and libido in m & f. |
| Estrogen | Female sex hormone, controls growth, devment of sndary sex characteristcs. Low estrogen + menopausal sx. |
| Androgens | Male sex hormones, including testosterone and androstenedine |
| James-Lange Theory | emotions reflect observations & experiences of visceral & muscular reactions to certain stimuli: we're sad because we are crying |
| Age and Sleep | With increasing age, total sleep time & REM sleep decrease. |
| Alpha wave | Pattern of electrical brain activity associated w/ relaxed wakefulness. |
| External Cues & Obesity | Obese people tend to eat in response to external cues more than hunger cues. Opp to normal wt people. |
| RNA | A nucleic acid found in a neuron. Believed to be involved with learning and memory. |
