A somato-cognitive action network alternates with effector regions in motor cortex - Nature - Nature
TL;DR Functional MRI studies reveal that the classic homunculus in the human motor cortex is in fact discontinuous, alternating with action control-linked regions termed the somato-cognitive action network.

Using precision functional magnetic resonance imaging methods, researchers found that the classic homunculus in the motor cortex is interrupted by regions with distinct connectivity, structure, and function, alternating with effector-specific areas. These regions exhibit decreased cortical thickness and strong functional connectivity to each other as well as to the cingulo-opercular network, critical for action and task set implementation.

Functional MRI studies across ages show that the classic homunculus of the motor cortex in humans is in fact discontinuous, alternating with action control-linked regions termed the somato-cognitive action network.
