Cerebral Hemispheres Flashcards
What is A?
Sulvus (dip)
What is a sulcus?
A depression in the cerebral cortex which surrounds a gyrus
What is B?
Gyrus (elevation)
What is a gyrus?
Elevation in the cerebral cortex surrounded by one or more sulci
Where is the grey and white matter found in the brain?
Grey matter on the surface
White matter inside
What is C?
Fissure (larger dip)
What is the basal ganglia?
Collection of neuronal cell bodies buried in the white matter
What is A?
Median longitudinal fissure
What is B?
Corpus collosum
What should be known about the pattern of sulci and gyri?
Is variable but some constant features must be remembered

What is A?
Precentral gyrus
What is B?
Central sulcus
What is C?
Postcentral gyrus
What is D?
Lateral sulcus
What is A?
Parieto-occipital sulcus
What is B?
Cingulate sulcus (and gyrus)
What is C?
Corpus collusum
What is the corpus collosum?
Thick band of nerve fibres that divides the cortex lobes into right and left
Connects the left and right sides of the brain,a llowing for communication between both hemispheres
What is the insula?
Small region of cerebral cortex lcoated deep within the lateral sulcus

What is cortical mapping?
Invasive procedure in which electrical stimulation is applied briefly to cortical surface for the purpose of identifying cortical areas for sensory, motor or language function
What are the different areas of the brain in cortical mapping called?
Brodmann areas
How many Brodmann areas are there?
52
What is the posterior part of the cerebral hemisphere responsible for?
Sensory information
What is the anterior part of the cerebral hemisphere responsible for?
Motor information
