What areas make up the prefrontal cortex?
In mammalian brain anatomy, the prefrontal cortex (PFC) is the cerebral cortex which covers the front part of the frontal lobe. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47.
What areas are in the frontal lobe?
There are at least 4 functionally distinct areas in the frontal lobes:
- the primary motor cortex in the precentral gyrus (located most posteriorly),
- the medial areas,
- the orbital areas,
- the lateral areas (prefrontal areas).
Which lobe contains the prefrontal gyrus?
frontal lobe
The front part of the frontal cortex is covered by the prefrontal cortex. There are four principal gyri in the frontal lobe. The precentral gyrus is directly anterior to the central sulcus, running parallel to it and contains the primary motor cortex, which controls voluntary movements of specific body parts.
What are the executive functions of the prefrontal cortex?
The prefrontal cortex is a key structure for performing executive functions. Top-down signals are used to retrieve specific information stored in long-term memory. The prefrontal cortex sends top-down signals to the posterior cortices to control information retrieval.
Which gyrus lies posterior of the inferior frontal gyrus?
precentral gyrus
The most posterior gyrus is the precentral gyrus, which lies between the Rolandic and the precentral sulci and contains the motor cortex and part of the premotor cortex.
What Brodmann’s areas are in the frontal lobe?
Brodmann areas 44 and 45 – Broca’s area Located within the frontal lobes, Broca’s area is an essential region for the production of language.
Where in the brain is amygdala located?
medial temporal lobe
The amygdala is located in the medial temporal lobe, just anterior to (in front of) the hippocampus. Similar to the hippocampus, the amygdala is a paired structure, with one located in each hemisphere of the brain.
¿Qué es la región prefrontal?
La région préfrontale correspond à la portion inexcitable antérieure du cerveau’ [ 11 ]. Frente a estas aportaciones anecdóticas, el legítimo artífice de la popularización del término prefrontal es, sin lugar a dudas, el médico escocés David Ferrier (1843-1928).
¿Cuál es la referencia más antigua del término prefrontal?
La referencia más antigua que hemos hallado del término ‘prefrontal’ data de 1868 y se encuentra en el tercer volumen de On the anatomy of vertebrates, del biólogo inglés Richard Owen (1804-1892).
¿Qué es la corteza prefrontal ventral?
En cambio, la corteza prefrontal ventral se interconecta con estructuras cerebrales relacionadas e implicadas con los procesos de emoción. Finalmente, cabe tener en cuenta que la corteza prefrontal recibe información de los sistemas de arousal del tronco del encéfalo, y su función es particularmente dependiente de su ambiente neuroquímico.
