|
Alexia
|
Inability to read.
|
|
|
PE
|
Receives input from somatosensory cortex; sends outpust to primary motor cortex, supplementary motor and premotor areas, and area PF; guides movements by computing lim position; plays the role of a primary area
|
|
|
PF
|
Receives somatosensory input from PE, motor and premotor cortex, and vsual input through area PG; outputs are similar to PE; plays the role of a supplementary area (i.e. elaboration of informatoin in PE).
|
|
|
PG
|
Receives muliple inputs (visual, somesthetic, propioceptive, auditory, vestibular, ocularmotor (eye movements), motivational (emotional/limbic input); plays the role of association cortex (inter-modal mixing); part of dorsal stream; controls spatially guided behavior using tactile and visual informatoin.
|
|
|
Hippocampus
|
Primitive cortical structure lying in the anterior medial region of the temporal lobe.
|
|
|
Acalculia
|
Inability to perform mathematical operations
|
|
|
Afferent paresis
|
Loss of kinesthetic feedback that results from lesions to the postcentral gyrus (areas 1,2,3) and produces clumsy movements.
|
|
|
Simultaneous extinction
|
Second stage of recovery from contralateral neglect; characterized by response to stimuli on the neglected side as if there were a simultaneous stimulatin on the contraleral side.
|
|
|
Asomatognosia
|
Loss of knowledge of sensory awareness of one's own body and bodily condition; may be on one or both sides of the body; most commonly results from damage to the right parietal lobe.
|
|
|
Anosognosia
|
Loss of ability to recognize or to acknowledge an illness or bodily defect; usually associated with right parietal lesions.
|
|
|
Angular gyrus
|
Gyrys in the parietal lobe coresponding roughly to Brodmann's area 39; important in language functions.
|
|
|
Cingulate cortex
|
Strip of limbic cortex lying just above the corpus callosum along the medial walls of the cerebral hemispheres.
|
|
|
Orbital frontal cortex
|
Lies adjacent to the cavity containing the eye but, anatomically defined, receives projections from the dorsomedial nucleus of the thalamus.
