Document Summary

Alpha activity: neural activity in the range of 8-12 hz. Attentional blink: the second of two targets cannot be detected or identified when it appears to be close. Brain plasticity: the brain"s ability to change throughout life. Blindsight: the ability to interact behaviorally with objects while remaining consciously unaware of them. Brain death: irreversible unconsciousness with complete loss of brain function. Beta activity: high-frequency neural oscillations in the range of 15-30 hz or 15-30 cycles per second; this activity characterizes an alert, wakeful state of consciousness. Bistable stimuli: ambiguous stimuli with more than one possible interpretation. Cell assembly: system of interconnected neurons that activates in a specific dynamic pattern; activation of part of the cell assembly sends signals that activate the remainder of its components. Corpus callosum: large bundle of axons that connects the cortex of the two cerebral hemispheres. Coma: a state of extreme unresponsiveness in which an individual exhibits no voluntary movement or discernible sleep-wake cycle.
