“…Di Giacomo et al (2018) found no change of theta band on the Fp1 channel when noninvasive brain stimulation was applied over the brain front-parietal area in subjects performing cognitive demand tasks. Lee et al (2020) maintained the amplitude of the low alpha band on left-dlPFC when a-tDCS was applied for 20-min over the F3 channel in subjects performing dual-task.…”

“…To explore the specificity of these regions coding for motor intention, the dorsolateral prefrontal cortex (DLPFC), a large brain region not usually considered to be involved in motor tasks, was included in the analysis. The posterior cingulate cortex [19] and fronto-polar cortex [20] were also included because of their involvement in the preparation for overt motor execution. The somatosensory area was included based on findings from neural recordings in monkeys, which demonstrated that neural activity in the postcentral cortex precedes active limb movement [21].…”

Motor intention is a high-level brain function related to planning for movement. Although studies have shown that motor intentions can be decoded from brain signals before movement execution, it was unclear whether intentions relating to mental imagery of movement could be decoded. Here, we investigated whether differences in spatial and temporal patterns of brain activation were elicited by intentions to perform different types of motor imagery and whether the patterns could be used by a multivariate pattern classifier to detect such differential intentions. The results showed that it is possible to decode intentions before the onset of different types of motor imagery from functional MR signals obtained from fronto-parietal brain regions, such as the premotor cortex and posterior parietal cortex, while controlling for eye movements and for muscular activity of the hands. These results highlight the critical role played by the aforementioned brain regions in covert motor intentions. Moreover, they have substantial implications for rehabilitating patients with motor disabilities.
