In recent years, there has been a major increase in publications on the PFC, especially using mice. Synaptic density increases throughout the juvenile period, peaking at the onset of puberty, where pruning of synapses yields an overall decrease in synaptic number in the mature brain. It is one of the last brain structures to develop in the course of evolution. However, inconsistencies in the nomenclature and anatomical boundaries of PFC areas has made it difficult for researchers to compare data and interpret findings across species. It is one of the most recently derived parts of the human brain.

One complication with this definition is that the electrically "silent" frontal cortex includes both granular and non-granular areas. The findings suggest that bilateral HD-tDCS on the dorsolateral prefrontal cortex improves cycling TT performance without altering the physiological and perceptual response at moderate intensity, indicating that an upregulation of the prefrontal cortex could enhance endurance exercise performance. The cerebral cortex, which is the outer surface of the brain, is associated with higher level processes such as consciousness, thought, emotion, reasoning, language, and memory. Table of Contents1 The Prefrontal Cortex and Planning2 Prefrontal Cortex and Self Control3 Prefrontal Cortex […] The neocortex is that part of the cerebral cortex (maybe 90% of it) that is the modern, most newly ("neo") evolved part. Motivated by the hypothesis that these functions provide a form of out-of-distribution Patients with damage to this region may exhibit 'cognitive' difficulties in organizing a behavioral response, memory retrieval, maintaining and shifting behavioral sets, generating motor programs . It undergoes a prolonged period of maturation which lasts until adulthood. Prefrontal cortex (in yellow). The prefrontal cortex matures lastly. For example, if loud noises distract the person, they might need to work in their own quiet room. For him, the prefrontal area was restricted to the anterior-most part of the frontal lobe (approximately corresponding to the frontal pole). In this study, the effects of high-definition transcranial direct current stimulation (HD-tDCS) on resting-state brain networks in the human prefrontal cortex were .
