Gray matter heterotopia is a neurological disorder caused by gray matter being located in an atypical location in the brain. [ 1] Grey matter heterotopia is characterized as a type of focal cortical dysplasia. The neurons in heterotopia are otherwise healthy; nuclear studies have shown glucose metabolism equal to that of normally positioned ...
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]
Dorsolateral prefrontal cortex. The dorsolateral prefrontal cortex ( DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. [ 1] The DLPFC is not an anatomical structure, but rather a ...
224850. Anatomical terms of neuroanatomy. [ edit on Wikidata] In mammalian brain anatomy, the prefrontal cortex ( PFC) covers the front part of the frontal lobe of the cerebral cortex. It is the association cortex in the frontal lobe. [ 2] The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45 ...
Cognitive deficits have been linked to greater lesion load, white matter lesion location, microstructural injury, gray matter lesions, cortical and subcortical gray matter brain atrophy, and discrepant patterns of cerebral activation. [67] Measures of tissue atrophy are well correlated with, and predict, cognitive dysfunction.
Spinal cord presents grey matter lesions, that can be confirmed post-mortem and by high field MR imaging. Spinal cord grey matter lesions may be detected on MRI more readily than GM lesions in the brain, making the cord a promising site to study the grey matter demyelination. [45] Myelin Water Fraction (MWF) shows lesions under MRI [46]
Neuroscience of sleep. The neuroscience of sleep is the study of the neuroscientific and physiological basis of the nature of sleep and its functions. Traditionally, sleep has been studied as part of psychology and medicine. [ 1] The study of sleep from a neuroscience perspective grew to prominence with advances in technology and the ...
The study, undertaken by scientists at the Max Planck Institute, challenges long-standing views and could lead to new treatment approaches for the disease. Although Alzheimer’s disease remains ...
