Flashcards in Organization of Cerebral Cortex Deck (10):
Give the generally information processing structure of a cortical column:
Layer IV receives thalamic input. Layer IV transmits information to layers II and III which associate with other cortical regions. Layers V and VI project to subcortical structures.
Layer IV neurons of which Brodmann's area(s) would receive input from the medial geniculate nucleus?
41 and 42 (Auditory Cortex)
Granular neurons in which Brodmann's area(s) would receive afferents from lateral geniculate nucleus?
17 (Visual Cortex (V1))
Granular neurons in brodmann's area 4 receive afferents from which thalamic nuclei?
Ventroanterior and Ventrolateral Nuclei
Brodmann's areas 1,2,3 receive afferents from which thalamic nucleus?
Ventral Posterior Nucleus
Efferents of mediodorsal nucleus of thalamus to cortex correspond to which sensory modality?
Corticostriatal projections originate in which cortical layer? Where do they terminate?
Layers V and VI, basal ganglia
Define the three types of output pathways of cortex:
Projection (corticofugal) - to subcortical structures
Association - to other cortical structures
Commisural - connect hemispheres
Name the structures of the corpus callosum:
Splenium, body, genu, rostrum, anterior commisure
