The team's next steps, he adds, are to evaluate and expand the list of procedures for which a transpalpebral orbitofrontal
craniotomy is best suited.
The research focuses special attention on the medial orbitofrontal
(11) areas of the frontal lobe.
The brain areas involved in satiety include the hypothalamus, orbitofrontal
cortex (OFC), insula, inferotemporal cortex, NAC, ventromedial prefrontal cortex (vmPFC), and limbic/paralimbic regions.
Importantly, elaborate momentary confabulations often involve damage to ventromedial prefrontal lobes and the diencephalon, while the behaviorally spontaneous confabulations involve damage to the posterior orbitofrontal
cortex or related anterior limbic structures.
Usando una metodologia similar, Bechara y colaboradores describieron la existencia de deficits especificos de los procesos de toma de decisiones en pacientes con danos selectivos en la corteza prefrontal ventromedial, que incluye la seccion medial de la corteza orbitofrontal
, seccion subgenual del giro cingulado y polo frontal (Bechara et al.
The cerebral blood-flow was bilaterally increased in the orbitofrontal
and subcallosial cingulate cortices, the right thalamus, and the left inferior parietal cortex, and was decreased bilaterally in the cingulate cortex.
Center for more primitive needs that enable the survival is concentrated in the evolutionary older brain areas (nucleus accumbens, orbitofrontal
cortex, anterior cingulate).
Chapter topics include: the role of prefrontal cholinergic receptors in the pathology of schizophrenia; participation of the prefrontal cortex in the processing of sexual and maternal incentives; the orbitofrontal
cortex and emotional decision-making; the role of the prefrontal cortex in cognitive impairment in Parkison's disease, and noradrenergic actions in prefrontal cortex as they relate to AD/HD.
The early perceptual processing of faces rely on occipital and temporal cortices that help in constructing a detailed representation from the available configuration of facial features while the subsequent facial expression recognition depends upon structures like amygdala and orbitofrontal
cortex that in turn link the perceptual representation of faces, built in the first phase, to the knowledge about emotions (Adolphs, 2002).
The main finding is that in people with obsessive compulsive disorder and their unaffected relatives, part of the orbitofrontal
cortex didn't kick in on line as it should have," said Samuel Chamberlain, a neuroscientist at the University of Cambridge, who led the study.
For instance, the brain imaging studies showed that dopamine partly regulates metabolic activity in the orbitofrontal
cortex, or OFC, a part of the brain that is key to controlling and planning behavior.
A traves de la estria terminal, se dirigen al nucleo hipotalamico paraventricular, el cortex orbitofrontal
y la circunvolucion del cingulo.
