Development of prefrontal cortex [PDF]

Neuropsychopharmacology, 2021
AbstractDuring evolution, the cerebral cortex advances by increasing in surface and the introduction of new cytoarchitectonic areas among which the prefrontal cortex (PFC) is considered to be the substrate of highest cognitive functions. Although neurons of the PFC are generated before birth, the differentiation of its neurons and development of ...

The whole prefrontal cortex is premotor cortex [PDF]

Philosophical Transactions of the Royal Society B, 2021
Abstract We propose that the entirety of the prefrontal cortex (PFC) can be seen as fundamentally premotor in nature. By this, we mean that the PFC consists of an action abstraction hierarchy whose core function is the potentiation and depotentiation of possible action plans at different levels of granularity.

Propofol Modulates Fear Memory Reconsolidation by Inhibiting D2 Receptor-Expressing Neurons in the Medial Prefrontal Cortex. [PDF]

Adv Sci (Weinh)
This study shows that propofol modulates fear‐memory reconsolidation in mice. It works by suppressing D2 receptor‐expressing neurons within the medial prefrontal cortex and their connections to the basolateral amygdala. D2‐receptor agonists reproduce this fear‐reducing effect, offering potential non‐anesthetic therapeutic strategies for trauma‐related ...

Alcohol and the Prefrontal Cortex [PDF]

, 2010
The prefrontal cortex occupies the anterior portion of the frontal lobes and is thought to be one of the most complex anatomical and functional structures of the mammalian brain. Its major role is to integrate and interpret inputs from cortical and sub-cortical structures and use this information to develop purposeful responses that reflect both ...

Prefrontal involvement in imitation learning of hand actions : effects of practice and expertise. [PDF]

, 2007
In this event-related fMRI study, we demonstrate the effects of a single session of practising configural hand actions (guitar chords) on cortical activations during observation, motor preparation, and imitative execution.

Functional specialization within rostral prefrontal cortex (Area 10): a meta-analysis [PDF]

, 2006
One of the least well understood regions of the human brain is rostral prefrontal cortex, approximating Brodmann's area 10. Here, we investigate the possibility that there are functional subdivisions within this region by conducting a meta-analysis of ...

Neural coding of tactile decisions in the human prefrontal cortex [PDF]

, 2006
The neural processes underlying tactile decisions in the human brain remain elusive. We addressed this question in a functional magnetic resonance imaging study using a somatosensory discrimination task, requiring participants to compare the frequency of
