This organization decreases upstream from primary motor cortex, ... we reconstructed neuronal activity specific to the button-press near the hand representation of left and right primary motor cortex.

Textbooks show the primary motor cortex as a continuous ribbon with sections devoted to specific muscle ... What they were seeing "just didn't make sense if the textbooks were right," Dosenbach says.

Textbooks show the primary motor cortex as a continuous ribbon with sections devoted to specific muscle groups, from tongue to toe. That view dates back to the 1930s, when Canadian neurosurgeon ...

Nico Dosenbach says one day they noticed something odd in the primary motor cortex, an area that controls muscles. NICO DOSENBACH: It just didn't make sense if the textbook was right.

That map of the primary motor cortex — the motor homunculus — shows how this brain region is divided into sections assigned to each body part that can be controlled voluntarily (SN: 6/16/15).

The CON “is one of the ‘smartest’ areas of the brain, and we’re seeing it connect very strongly with these regions of primary motor cortex.” This alters our perception of the primary motor cortex's ...

The homunculus map of the primary motor cortex (left), compared to the updated map (right). The new map includes regions that control whole-body movements. Gordon, et al. via Nature under CC BY 4.0 ...

University of Alberta researchers have identified a neurochemical marker related to the loss of motor function and communication breakdown between the primary motor cortex—the part of the brain ...

The motor cortex is a part of the mammalian brain and is known to support the planning and control of voluntary body movements. Some past neuroscience studies, however, found that the motor cortex ...
