The motor cortex homunculus is getting a makeover. New research has essentially redrawn the motor cortex and constitutes one of the most substantial shifts in our topographical knowledge of a sensory ...

Since the 1930s, the so-called homunculus map has shown how different parts of the brain's motor cortex may control movement to different parts of the body. But it may be missing an important ...

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 ...

The idea of the homunculus dates to the late nineteenth century, when researchers noticed that electrically stimulating the primary motor cortex corresponded to specific body parts twitching.

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).

Study: A somato-cognitive action network alternates with effector regions in motor cortex. Image Credit: r.classen/Shutterstock.com. Background. The human motor cortex was initially described as a ...

Volitional motor control involves not only the initiation of desired movements but also the suppression of undesired movements. In this Opinion article, Ebbesen and Brecht argue that motor cortex ...

It's a depiction of the motor homunculus, which is essentially a "map" of the body located in the brain.The image shows how different spots of the primary motor cortex control different parts of the ...
