|
Define Prefrontal Cortex.
|
Cortex lying in fron of the primary and secondary motor cortex and thus the association, or tertiary, cortex in the frontal lobe.
|
lyring in front of
|
|
|
Define Entorhinal Cortex.
|
Cortex found on the medial surface of the temporal lobe; provides a major rout for neocortical input to the hippocampal formation; often shows degeneration in Alzheimer's disease.
|
medial surface
|
|
|
Define binding and reentry.
|
-Binding - how sensations in specific channels (touch, vision, hearing, and so forth) combine into perceptions that translate as a unified experience the we call reality.
-rentry - process by which cortical regions send projections back to regions from which they receive afferents; proposed as a mechanism for solving the binding problem. |
-combine
-send back |

|
Define Sylvian fissure.
|
(aka lateral fissure)Deep cleft in the basal surface of the brain that extends latterally, posteriorly, and upward, thus separating the temporal and parietal lobes.
|
seperating lobes
|
|
|
Define Heschl's gyrus.
|
Gyrus of human temporal lobe that is roughly equivalent to audotory area I. Also known as the transverse temporal guyrus.
|
temporal lobe
|
|
|
Define Planum temporale.
|
Cortical area just posterior to the auditory cortex (Heschl's gyrus) within the Sylvian fissure.
|
posterior to the
|
|
|
Define medial geniculate.
|
group of nuclei that receive auditory projections and relays information to the appropriate targets.
|
group of nuclei
|
|
|
Define Broca's area.
|
Region of the left frontal lobe (frontal operculum) believed to take part in the production of language. Damage to this are results in Broca's aphasia.
|
region of the left
|
|
|
Define Wernicke's area.
|
Posterior part of the superior temporal gyrus, roughly equivalent to area 22.
|
posterior part of the
|
|
|
Define double dissociation.
|
Experimental technique by which two areas of neocortex are functionally dissociated by two behavioral tests, each test being affected by a lesion in one zone and not the other. (i.e. mirriored images but different functions
|
two areas of the neocortex
|
|
|
Define Chimeric figures test.
|
used to demonstrate the special role of the right hemisphere in facial recognition.
|
right himisphere
|
|
|
Define dichotic listening.
|
Procedure for simultaneously presenting a different auditory input to each ear through sterophonic earphones.
|
procedure for
|
|
|
Define Wada test.
|
To prevent damage to the speech zones of patients about to undergo brain surgery, surgeons inject sodium amobarbital into the carotid artery. The sodium amabarbital anesthetizes the hemisphere where it is injected allowing the surgeon to determine whther that hemisphere is dominant for speech.
|
prevent damage in speech zones
|
|
|
Define apraxia.
|
Inability to make voluntary movements in the absence of paralysis or other motor or sensory impariment; especially an inability to make proper use of an object.
|
Inability to make
|
|
|
Define aphasia.
|
Detect or loss of power of expression by speech, writing, or signs or of comprehending spoken or written language due to injury or disease of the brain.
|
loss of power of
|
|
|
Define agnosia.
|
Partial or complete inability to recognize sensory stimuli, unexplainable by a defect in elementary sensation or by a reduced level of alterness.
|
Partia or complete inability
