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 ...
Examples of such cross-modal functions are emotional regulation strategies such as emotional suppression [1] and emotional reappraisal, [1] [2] the effect of mood on cognitive tasks, [3] and the effect of emotional stimulation of cognitive tasks. [4]
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans. [2]
The uncinate fasciculus is a bi-directional pathway between the temporal lobe and frontal lobe; it is traditionally considered to be part of the limbic system. [2] It has been proposed that the uncinate fasciculus allows mnemonic representations stored in the temporal lobe to interact with and guide decision making in the frontal lobe. [4]
The volume of the human BA10 is about 14 cm 3 and constitutes roughly 1.2% of total brain volume. This is twice what would be expected in a hominoid with a human-sized brain. By comparison, the volume of BA10 in bonobos is about 2.8 cm 3, and makes up only 0.74% of its brain volume. In each hemisphere, area 10 contains an estimated 250 million ...
In human anatomy, the piriform cortex has been described as consisting of the cortical amygdala, uncus, and anterior parahippocampal gyrus. [1] More specifically, the human piriform cortex is located between the insula and the temporal lobe , anteriorly and laterally of the amygdala.
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. [2]
The parietal lobe is located directly behind the central sulcus, superior to the occipital lobe and posterior to the frontal lobe, visually at the top of the back of the head. [18] The make up of the parietal lobe is defined by four anatomical boundaries in the brain, providing a division of all the four lobes. [18]
