The ability to execute precise movements depends on transforming visuospatial information about the goal of the movement into a movement plan. In the nonhuman primate, discrete parts of premotor frontal and parietal cortex appear to code for movements of different effectors. However, the evidence regarding homologous effector selectivity within the human brain remains inconclusive. Here, we aimed to ask how human brains code spatial information during the motor planning process for eye and hand movements and test whether spatial-specific planning is effector-dependent.
Continue readingDecoding working memory (WM) contents from visual cortex has been widely found in human neuroimaging studies, demonstrating the idea that visual WM storage uses similar encoding mechanism as visual perception in the visual cortex. However, researchers have found evidence both support and against this hypothesis. Most of these studies, no matter for or against the hypothesis, relied on decoding the orientation of gratings with fMRI voxel responses.
