Broca's area, or the Broca area (/ ˈ b r oʊ k ə /, [1] [2] [3] also UK: / ˈ b r ɒ k ə /, US: / ˈ b r oʊ k ɑː / [4]), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain [5] with functions linked to speech production. Language processing has been linked to Broca's area since Pierre Paul Broca ...
The subcallosal area (parolfactory area of Broca) is a small triangular field on the medial surface of the hemisphere in front of the subcallosal gyrus, from which it is separated by the posterior parolfactory sulcus; it is continuous below with the olfactory trigone, and above and in front with the cingulate gyrus; it is limited anteriorly by the anterior parolfactory sulcus.
Map of Color of Skin: Figures indicate tint in Broca's scale Broca is known for making contributions towards anthropometry —the scientific approach to measurements of human physical features. He developed numerous instruments and data points that were the basis of current methods of medical and archeological craniometry .
Broca named the limbic lobe in 1878, identifying it with the cingulate and parahippocampal gyri, and associating it with the sense of smell - Treviranus having earlier noted that, between species, the size of the parahippocampal gyrus varies with the size of the olfactory nerve. [2]
The human brain has two hemispheres, and each one looks similar to the other; that is, it looks like one hemisphere is a mirror image of the other. However, Foundas, et al. found that the pars triangularis in Broca's area is actually larger than the same region in the right side of the brain. This "leftward asymmetry" corresponded both in form ...
The French anatomist Paul Broca, for whom Broca's area in the frontal lobe of the brain is named, died in 1880. His own brain became part of the collection of brains held by the Musée de l'Homme. Carl Sagan wrote about holding the brain in his hands in his 1979 book Broca's Brain. The brain is kept in a low cylindrical bottle, fragmented, and ...
Human skin is similar to most of the other mammals' skin, and it is very similar to pig skin. Though nearly all human skin is covered with hair follicles, it can appear hairless. There are two general types of skin: hairy and glabrous skin (hairless). The adjective cutaneous literally means "of the skin" (from Latin cutis, skin).
The limbic system was originally defined by Paul Broca as a series of cortical structures surrounding the boundary between the cerebral hemispheres and the brainstem. The name "limbic" comes from the Latin word for the border, limbus, and these structures were known together as the limbic lobe. [6]
