Moving a hand is like sailing: your motor cortex, the captain, receives hand location information to define movement parameters; and throughout the movement, your somatosensory areas, the localization equipment, gather data to ensure your hand is on the correct course, and to guide the captain in further commands. Models of information flow in primates suggest that during volitional movement, the sensory state information in Brodmann Area 3b (Ba3b) is spread to Ba4, then sent to muscles via motor commands, followed by muscle proprioceptive information through the thalamus to Ba2, and finally b

The ability to withhold a response and appropriately time one’s actions is an essential component of goal-directed behavior. Aspects of such cognitive control in rodents are supported by the medial prefrontal cortex (mPFC). The mPFC and its subareas are a site of distinct delay-related activity during motor preparation. However, how mPFC integrates relevant information and exercises the control over behavioral responses remains incompletely understood. Here we characterized local field potentials (LFPs) within mPFC with a focus on the detection of beta bursts – discrete oscillatory events in t
