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.

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, ...

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).

Researchers found that the local release of dopamine – a molecule best known for its role in the brain’s reward system – is a key factor in acquiring new motor skills.

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 motor cortex, the part of the brain involved in the planning, control, and execution of voluntary movements, may play a role in translating vocabulary from foreign languages into a person’s native ...

The primary motor cortex has an important role in the precise execution of learned motor responses. During motor learning, synaptic efficacy between sensory and primary motor cortical neurons is ...

Overall, the research demonstrated that diminished dopamine signaling, whether acute or chronic, has profound effects on the excitability of primary motor cortex neurons.

A new interdisciplinary study by researchers from the Ruth and Bruce Rappaport Faculty of Medicine and the Andrew and Erna Viterbi Faculty of Electrical and Computer Engineering at the Technion ...
