Brodmann area 11 is a subdivision of the frontal lobe of the guenon monkey defined on the basis of cytoarchitecture (Brodmann-1905). Distinctive features: area 11 lacks an internal granular layer (IV); larger pyramidal cells of sublayer 3b of the external pyramidal layer (III) merge with a denser self-contained collection of cells in the internal pyramidal layer (V); similar to area 10 of ...
The fibers from the retina run along the optic nerve to nine primary visual nuclei in the brain, from which a major relay inputs into the primary visual cortex. A fundus photograph showing the back of the retina. The white circle is the beginning of the optic nerve. The optic nerve is composed of retinal ganglion cell axons and glia.
The portion of the inferior frontal lobe immediately adjacent to the longitudinal fissure (and medial to the medial orbital gyrus and olfactory tract) is named the straight gyrus,(or gyrus rectus) and is continuous with the superior frontal gyrus on the medial surface.
When von Bonin and Bailey constructed a brain map for the macaque monkey, they found the description of Brodmann inadequate and wrote: "Brodmann (1907), it is true, prepared a map of the human brain which has been widely reproduced, but, unfortunately, the data on which it was based was never published" [8] They instead used the ...
The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making.In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47.
Despite the title, Fantastic Voyage II: Destination Brain is not a sequel to Fantastic Voyage. The latter is a novelization that Asimov wrote from the 1966 film of the same name. Asimov was never quite happy with the novelization because although he was able to change some of the scientific details, it was not entirely his own work.
Simplified diagram of frontal cortex to striatum to thalamus pathways. There are five defined frontostriatal circuits: motor and oculomotor circuits originating in the frontal eye fields are involved in motor functions; while dorsolateral prefrontal, orbital frontal, and anterior cingulate circuits are involved in executive functions, social behavior and motivational states.

The posterior cingulate cortex is highly connected and one of the most metabolically active regions in the brain, but there is no consensus as to its cognitive role. [4] [5] Cerebral blood flow and metabolic rate in the PCC are approximately 40% higher than average across the brain. The high functional connectivity of the PCC, signifies ...
