Lobe frontalLe lobe frontal est une région du cerveau des vertébrés. Il est situé à l'avant des lobes pariétal et temporal. Dans le cerveau humain, le sillon central (ou scissure de Rolando) sépare le lobe frontal du lobe pariétal tout au long de la surface du cortex cérébral. Le sillon latéral (ou scissure de Sylvius) sépare le gyrus (ou circonvolution) frontal inférieur du lobe temporal.
Lateral prefrontal cortexIn human brain anatomy, the lateral prefrontal cortex (LPFC) is part of the prefrontal cortex (PFC). According to Striedter the PFC of humans can be delineated into two functionally, morphologically, and evolutionarily different regions: the ventromedial PFC (vmPFC) present in all mammals and the LPFC present only in primates. The LPFC contains the Brodmann areas BA8, BA9, BA10, BA45, BA46, and BA47. Some researchers also include BA44.
History of neuroimagingThe first neuroimaging technique ever is the so-called 'human circulation balance' invented by Angelo Mosso in the 1880s and able to non-invasively measure the redistribution of blood during emotional and intellectual activity. Then, in the early 1900s, a technique called pneumoencephalography was set. This process involved draining the cerebrospinal fluid from around the brain and replacing it with air, altering the relative density of the brain and its surroundings, to cause it to show up better on an x-ray, and it was considered to be incredibly unsafe for patients (Beaumont 8).
