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 ...
In neuroscience, the default mode network ( DMN ), also known as the default network, default state network, or anatomically the medial frontoparietal network ( M-FPN ), is a large-scale brain network primarily composed of the dorsal medial prefrontal cortex, posterior cingulate cortex, precuneus and angular gyrus.
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.

Effects of sleep deprivation on cognitive performance. The effects of sleep deprivation on cognitive performance are a broad range of impairments resulting from inadequate sleep, impacting attention, executive function and memory. An estimated 20% of adults or more have some form of sleep deprivation. [1] It may come with insomnia or major ...
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse') is a major component of the brain of humans and other vertebrates.Humans and other mammals have two hippocampi, one in each side of the brain.
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 ...
Grey matter, or brain matter in American English, is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil ( dendrites and unmyelinated axons ), glial cells ( astrocytes and oligodendrocytes ), synapses, and capillaries. Grey matter is distinguished from white matter in that it contains numerous cell ...
The neocortex then reviews and processes memories, which moves them into long-term memory. When one does not get enough sleep it makes it more difficult to learn as these neural connections are not as strong, resulting in a lower retention rate of memories. Sleep deprivation makes it harder to focus, resulting in inefficient learning.
