“…Studies discuss the issues that were already discussed in 1996 [31][32][33] . In a study carried out with fMRI in monkeys, the author identified that during hand and mouth movement, the level of cortical activation was higher, awakening about 532 neurons in the rostral part of inferior area 6 (area F5), where mirror neurons are located 34 .…”

“…In 2019, another study with 16 participants and recognized a complementary cortical activation area located in the medial parietal area of the parietal lobe 19 . This area is called precuneiform and it is a supplementary motor area that is mirrored to the primary motor area, having What is understood about the somatotopic condition of the brain then, is that the precentral cortex is not the only one to have activity during the performance of body functions, but that there are other areas that contribute to movement or sensory performance, as is defended by scholars 32,33 . Therefore, the brain works in an integrated way with several areas when performing a motor or sensory activity 34 .…”

Objective. To analyse the relationship between the level of brain activity during the hand motor act and swallowing in studies that used Functional Magnetic Resonance Imaging (FMRI). Method. A narrative literature review was carried out, and the data sources were obtained from Pubmed, BVS, and Google Scholar platforms. Results. Few studies were found that investigated the neurological activation correlated to the movement of hands and swallowing through FMRI, but all studies show a topographic relationship between the main areas for activity of hands and swallowing, as well as some studies showing some neurofunctional relationship between both concurrent activities. Conclusion. It is known that the precentral gyrus has significant areas innervating the hands and oral cavity, which are in nearby areas, being subject to questions about function interactions. The findings already described may encourage studies and discussions, but more research is needed to describe and measure the relationship between the motor areas of the hands and swallowing.

Electrocorticogram (ECoG) is an electrophysiological signal that results from the summation of neuronal activity near the cortical surface. To record ECoG signals, the scalp and skull are surgically opened and electrodes are placed on the cortical surface, either epidurally or subdurally. Owing to its improved spatiotemporal resolution and signal quality compared with electroencephalography, it is widely used to diagnose and treat neurological disorders in clinical settings for several decades, despite the invasiveness of ECoG. Recently, ECoG is applied in research to explore brain functions and connectivity, brain‐computer interfaces, and brain‐machine interfaces. In addition to the need for ECoG in neuroscience research, ECoG devices have advanced in terms of materials, fabrication, and function to overcome the limitations of commercially available ECoG arrays. Here, the conventional use of ECoG in clinical medicine, the new applications of ECoG in basic neuroscience research, and the future challenges in translating recent developments in ECoG devices for clinical use are described.
