Past studies showed that the motor cortex plays a crucial role in the human ability to translate intentions into actions. Yet the processes via which it enables the execution of precise and ...

The motor cortex homunculus is getting a makeover ... Even at the time of Penfield, evidence from human electrophysiology experiments suggested there was more to the M1. For example, ...

The human motor cortex was initially described as a continually present homunculus. Contrastingly, non-human primate (NHP) studies divided M1 into anterior and posterior regions, with the body ...

While previous experiments had tracked this electrical brain circuit to the motor cortex in mammals, the field has struggled to determine where discharge signals originate in the human motor cortex.

The Penfield-Boldrey research suggests that the primary motor cortex is just made up of the ... taken from several major databases, such as the Human Connectome Project and the UK Biobank, finding ...

The motor cortex is organized in a way that correlates to a distorted representation of the human body called the cortical homunculus, where greater areas of the cortex are dedicated to parts of the ...

Previous experiments had tracked this electrical brain circuit to the motor cortex in other mammals, but the field has struggled to determine where discharge signals originate in the human motor ...
