	Postcentral gyrus - Wikipedia, the free encyclopedia
		Brodmann area 3 is in red, area 1 in green, and area 2 in yellow.
		Brodmann areas 3, 1 and 2 comprise the primary somatosensory cortex of the human brain.
		Because Brodmann sliced the brain somewhat obliquely, he encountered area 1 first; however, from rostral to caudal the Brodmann designations are 3, 1 and 2, respectively.

	Neurological Exam: Cerebrum: Anatomy
		Brodmann’s areas 3, 2,1 (on the postcentral gyrus) is the primary somatosensory cortex; area 17 (cuneus and lingual gyri) receives visual input; area 41 (transverse temporal gyrus) is for auditory sense.
		Areas 5 and 7 are secondary to somatosensory areas 3,2,1; areas 18 and 19 are secondary to visual area 17; areas 42 and 22 are secondary to auditory area 41; area 28 is secondary to olfactory area 34.
		Parietal areas 39 and 40, i.e., the angular and supramarginal gyri, lie at the junction of the parietal, occipital, and temporal lobes and integrate tactile-kinesthetic, visual, and auditory association areas at the highest level.

	Sensory system - Wikipedia, the free encyclopedia
		Area V1 is the region of the brain which is engaged in vision.
		Visual Area 1, or V1, is used for vision, via the visual system to the primary visual cortex.
		Somatosensory Area 1, or S1, is for touch and proprioception in the somatosensory system.

	The Human Brain
		Brodmann assigned numbers to various brain regions by analyzing each area's cellular structure starting from the central sulcus [the boundary between the frontal and parietal lobes].
		As you may notice, many of the areas that are involved in the same general cognitive functions are numbered sequentially (or almost).
		Areas that perform the same tasks use essentially the same types of cells.

	Abstract 1 (Site not responding. Last check: 2007-11-02)
		The effects of age and Brodmann areas were analyzed with a nested multiple analysis of variance design.
		(2) There was a significant age effect, with a substantial decline in dendritic neuropil from the younger (< 50 years) group to the older (> 50 years) group, especially in spine measures, which decreased almost 50%.
		(3) Dendritic values were relatively stable after 40 years of age, suggesting that dendritic/spine degeneration in older, relatively healthy individuals may not be an inevitable consequence of the aging process.

	Prof. Dr. Korbinian Brodmann 1868-1918
		Korbinian Brodmann was born on 17 November 1868 in Liggersdorf, Hohenzollern, the son of a farmer.
		Brodmann's career in Berlin was marred by the surprise rejection by the Medical Faculty of his 'Habilitation' thesis on the prosimian cortex.
		Brodmann was normally very strong and healthy, and even saw his illness as a way of catching up a backlog of work.

		For examples, Brodmann's area 17 is synonymous with the primary visual cortex, whereas Brodmann's areas 3,1,2, denote and identify the primary somesthetic receiving areas.
		If the right parietal area is severely injured, the left half of the body image, and in fact all memories of the left half of the body and the left half of space, may be abolished; a condition referred to as unilateral neglect.
		Area 17 is referred to as "striate cortex" due to the striped appearance of layer IV, which is also directly innervated by the LGN.

		The function of the thalamus is to pass impulses on to the cerebralcortex, and it is presumed that these impulses are integrated by the association nuclei in the thalamus before being relayed.
		The classic view is that the trigeminal lemniscus (combining the ventral and dorsal secondary trigeminal tracts) projects to the medial portion (arcuate nucleus) of the posteroventral nucleus of the thalamus....
		From the posteroventral nucleus of the thalamus, third order neurons pass in the sensory radiation via the posterior limb of the internal capsule to the somatic sensory area of the cortex in the lowest portion of the postcentral areas (Brodmann's areas 3.

	CJNS-The World of Touch - From Evoked Potentials to Conscious Perception
		This representation became known as the secondary (SII) somatosensory area, as opposed to the primary (SI) area occupying the postcentral gyrus.
		They were able to show that three of the cytoarchitectonic areas (3b, 1 and 2) each contained a complete map of the contralateral body surface with area 3a, the rostral subdivision of area 3, probably containing a fourth map; the representations in 3b and 1 were mirror images of each other (Figure 3).
		Kaas and associates found that the great majority of cells in 3b and 1 responded to skin stimulation, whereas most 3a neurones were driven by muscle spindles; area 2 cells ultimately received inputs from joint or cutaneous afferents (cf.

	"The Somatic-Sensory System," by Therial L. Bynum, M.D.
		In man, these areas lie mainly in the anterior portion of the Parietal lobes.
		Two distinct and separate areas are known to receive direct afferent nerve fibers from the relay on nuclei of the Thalamus; called Somatic Sensory Area I (SSA-I) and Somatic Sensory Area II (SSA-II).
		The basic organization of these receptors however, is the same as those found in vision and audition, because the membrane potential of each is altered by a particular form of energy, and because each has its own receptive field, which is an area of body tissue.

		After 1 year on study, there was no depletion of the non-protein sulfhydryl levels in the liver or the kidneys (Rampy et al., 1977).
		The mean numbers of affected fetuses per litter, all litters considered, were 0.33 (3% of the fetuses in the litter), 1.27 (12% of the fetuses in the litter), and 1.41 (13% of the fetuses in the litter), respectively.
		Because a dosimetric adjustment was used, the default value of 3 for toxicokinetic differences was reduced to 1; the default value of 3 for toxicodynamic differences was retained.

		Appreciation of the image is done in a variety of association areas, particularly on the parietal and temporal lobes of the hemisphere.
		The cortex of area 17 is a mixture of simple and complex fields, and their interaction draws both the outlines (including stopping points) and relative movement of visual images.
		The midbrain tectum also receives axons from Brodmann area 19 of the cerebral cortex--the part of the primary occipital lobe cortex devoted to conscious direction of the gaze based on reception and appreciation of images.

		They are illuminations, revelations, full of significance and importance, all inarticulate though they remain; and as a rule they carry with them a curious sense of authority for after-time <3>.
		The two-fold key to this implication is: (1) appreciating the major role that the limbic brain plays in synesthesia; and (2) considering newer non-hierarchical models of brain organization.

		One main path for verifying specific hypotheses about the way in which limited capacity affects cognitive functioning is to compare individuals or groups that are presumed to differ in WM capacity.
		In recent years, the role of the PFC and more specifically its dorsolateral region (Brodmann areas 9, 10 and 46) has been studied extensively by various researchers.
		Deterioration in performance is found even with delays of only a few seconds, and even if the lesion is in certain parietal, hippocampal and sub-cortical regions, which are significantly interconnected with the PFC at a neural level (Koch and Fuster, 1989; Kojima and Goldman-Rakic, 1982, 1984).

		The deduction condition resulted in activation of the left inferior frontal gyrus (Brodmann areas 45, 47).

		Induction was distinguished from deduction by the involvement of the medial aspect of the left superior frontal gyrus (Brodmann areas 8, 9).
