“…Thus, the cortical thickness of the primary motor cortex is greater than that of the somatosensory cortex. Likewise, according to Brodmann, von Economo, and Koskinas, area 1 has similar regions to the premotor cortex in area 6 [ 1 , 5 ].…”

“…Brodmann’s cytoarchitectural analysis found the internal granular layer absent in the PMC and SMA but not in the PSC. Immediately following Brodmann’s discovery, Von Economo and Koskinas classified the neocortex into five parts: agranular, frontal, parietal, polar, and granular [ 1 ]. Based on these classifications, the PMC was considered part of the agranular cortex.…”

The cerebral cortex, comprising six layers known as the neocortex, is a sheet of neural tissue that contains regions for neurosurgical planning, including the primary motor cortex (PMC), the supplementary motor cortex (SMA), and the primary somatosensory cortex (PSC). However, knowledge gaps persist concerning the transition points between areas 3 to 4 and 4 to 6 and the SMA's extent. This study aims to develop a noninvasive protocol using T1/T2 weighted imaging to identify crucial anatomic borders around the primary and supplementary motor cortex for neurosurgical planning. A comprehensive literature search on the cytoarchitectonic borders of Brodmann's areas 3a, 4, and 6 was conducted, and relevant articles were selected based on their examination of these borders. The primary motor cortex was found to be the thickest region in the human brain, with discernible differences in thickness between areas 4 and 6. T2-weighted images revealed significant cortical thickness differences between the precentral and postcentral gyrus. Various methods have been employed to parcellate borders between cortical regions, including Laplace's equation and equi-volume models. A triple-layer appearance in the primary motor cortex and a novel method based on myelin content demonstrated consistent agreements with historically defined cytoarchitectonic borders. However, differentiating areas 4 and 6 from MR imaging remains challenging. Recent studies suggest potential methods for pre-surgically identifying the primary motor cortex and examining differences in cortical thickness in diseases. A protocol should be established to guide neurosurgeons in accurately identifying areas 4 and 6, possibly using imaging modalities superimposed on myelin maps for differentiation and determining area 6's anterior extent.

La encefalitis letárgica de von Economo es un trastorno neuropsiquiátrico de posible origen autoinmunitario, en el cual se afectan los ganglios basales. Esta reacción puede ocurrir luego de una infección aguda por diversos agentes virales o bacterianos. Dado que aparece cuando ya se ha resuelto el cuadro agudo, se ha propuesto el mecanismo del mimetismo molecular para explicar la lesión autoinmunitaria. Se han reportado diversos casos a lo largo del tiempo, pero fue con la pandemia de influenza de 1918, conocida como la gripe española, que la encefalitis letárgica alcanzó niveles de epidemia, con casos reportados hasta 1923 en diversos países.La pandemia de la gripe española se extendió a Colombia durante los últimos meses de 1918 y afectó varias ciudades, principalmente Bogotá, donde se reportó el mayor número de enfermos y muertos. Con este trabajo se busca rememorar, cien años después, el ingreso de la gripe española a nuestro país y sus principales complicaciones, entre las que se describieron algunos casos de encefalitis letárgica.
