PYC 3703 ALL CHAPTERS QUESTIONS AND ANSWERS
Action potential - Ans - a neural impulse; a brief electrical charge that travels down an axon - the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell. Axons - Ans a part of a neuron that carries impulses away from the cell body Broca's area - Ans Controls language expression - an area of the frontal lobe, usually in the left hemisphere, that directs the muscle movements involved in speech. Cell body - Ans Largest part of a typical neuron; contains the nucleus and much of the cytoplasm Cerebral cortex - Ans - outer region of the cerebrum, containing sheets of nerve cells; gray matter of the brain - the intricate fabric of interconnected neural cells that covers the cerebral hemispheres; the body's ultimate control and information-processing center Cognitive neuroscience - Ans - the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language) - A field that attempts to understand the links between cognitive processes and brain activity. - study of the physical changes in the brain and nervous system during thinking Dendrites - Ans - receive messages from other cells - Branchlike parts of a neuron that are specialized to receive information. Distributed representation - Ans - occurs when a specific cognition activates many areas of the brain - the idea that specific cognitive functions activate many areas of the brain - a representation in which information is coded as a pattern of activation distributed across many different nodes Double dissociation - Ans The phenomenon in which one of two functions, such as hearing and sight, can be damaged without harm to the other, and vice versa. Electroencephalogram - Ans An amplified recording of the waves of electrical activity that sweep across the brain's surface. These waves are measured by electrodes placed on the scalp. Event-related potentials (ERP) - Ans The recording of participant brain activity using a stretchy cap with small electrodes or sensors as participants engage in a particular task (commonly viewing photographs or listening to auditory stimuli). Extrastriate body area (EBA) - Ans An area in the temporal cortex that is activated by pictures of bodies and parts of bodies, but not by faces or other objects. Feature detectors - Ans - neurons that respond selectively to very specific features of more complex stimuli - nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement
