Two main frontal areas have been implicated in the dream process. The first involves the deep white matter of the frontal lobes (just above the eyes). The main systems at work here involve the mesolimbic and mesocortical dopaminergic pathways. There are connecting fibres that run between frontal and limbic structures.
The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is parted from the parietal lobe by a groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral ...
Cortical white matter increases from childhood (~9 years) to adolescence (~14 years), most notably in the frontal and parietal cortices. [8] Cortical grey matter development peaks at ~12 years of age in the frontal and parietal cortices, and 14–16 years in the temporal lobes (with the superior temporal cortex being last to mature), peaking at about roughly the same age in both sexes ...
Frontal release signs are primitive reflexes traditionally held to be a sign of disorders that affect the frontal lobes. The appearance of such signs reflects the area of brain dysfunction rather than a specific disorder which may be diffuse, such as a dementia, or localised, such as a tumor.
Anatomical comparison between the brain of a lizard (A and C) and the brain of a turkey (B and D). Abbreviations: Olf, olfactory lobes; Hmp, cerebral hemispheres; Pn, pineal gland ; Mb, optic lobes of the middle brain ; Cb, cerebellum; MO, medulla oblongata; ii, optic nerves; iv and vi, nerves for the muscles of the eye; Py, pituitary body.
The specific regions that show the most robust correlation between volume and intelligence are the frontal, temporal and parietal lobes of the brain. [ 10 ] [ 11 ] [ 12 ] A large number of studies have been conducted with uniformly positive correlations, leading to the generally safe conclusion that larger brains predict greater intelligence.
Dreamily gazing at the album covers of Elvis Presley was not, statistically speaking, a rare habit among American teen girls in the late 1950s and early ’60s. Priscilla was just 14 years-old ...
The basis for this discovery was the analysis of speech problems resulting from injuries to this brain region, located in the inferior frontal gyrus. Lesions to Broca's Area result primarily in disruptions to speech production. Damage to Wernicke's area, located in the lower part of the temporal lobe, mainly leads to speech reception disruptions.
