Cerebral Cortex and Basal Ganglia Flashcards
Elevated ridges “winding” around the brain
Gyri
Small grooves dividing the gyri
Sulci
Divides the frontal from the parietal lobe
Central Sulcus
Deep grooves, generally dividing large
regions/lobes of the brain
Fissures
Divides the two cerebral hemispheres
Longitudinal fissure
Separates the cerebrum from the cerebellum
Transverse Fissure
Divides the temporal lobe from the frontal
and parietal lobes
Sylvian/Lateral Fissure
It plays an integral role in the following functions/actions: •Motor •Integrative functions •Memory Formation •Emotions •Decision Making/Reasoning •Personality
Frontal Lobe
BRODMANN AREAS (BA) relate specifically to motor activities
Brodmann’s areas 4, 6, 8, and 44
BRODMANN AREAS (BA) imprecisely determined functions involved in the initiation of planned action and executive control of all mental operations, including emotional expression
BA 9 to 12 and 45 to 47
BRODMANN AREAS (BA)
connected with the ocular and other brainstem motor nuclei
With identical areas of the other cerebral hemisphere through the corpus callosum
BA 8 and 6
BRODMANN AREAS (BA) primary sensory cortex projects to the superior parietal lobule
BA 5
BRODMANN AREAS (BA) contains cells that are activated by the homolateral geniculocalcarine pathway
BA 17
Frontal components of the limbic system and take part in the control of respiration, blood pressure, peristalsis, and other autonomic functions
medial-orbital gyriand anterior parts of the cingulated gyri
Provide most of the cerebral efferent motor system that forms the pyramidalor corticospinaltract
frontal agranular cortex
Play an integral role in the following functions:
Hearing
Organization/Comprehension of language
Information Retrieval (Memory and Memory Formation)
Temporal Lobe
Responsible for hearing
Primary Auditory Cortex
