The role of neuron and dopamine loss in Parkinson's Disease (PD) has long been recognized by neuroscientists. However, how dopaminergic modulation affects brain regions involved in the control of ...

For almost a century, budding neuroscientists have been taught that the headband-like strip of brain tissue over our ears ...

David A. Leopold is in the Section on Cognitive Neurophysiology and Imaging, National Institute of Mental Health, Bethseda, Maryland 20814, USA. In the 1930s, the neurosurgeon Wilder Penfield ...

Gliomas grow and invade along white matter fiber tracts. This study assessed the effects of motor cortex gliomas on the cerebral white matter fiber bundle skeleton. The motor cortex glioma group ...

In a recent study published in the Nature Journal, researchers performed precision functional mapping (PFM) and functional magnetic resonance imaging (fMRI) to map the functional organization of the ...

Researchers have discovered that the dorsal premotor cortex serves a 'meta-learning' function, overseeing and regulating physical movements. Once believed to be limited to movement planning, this ...

Researchers discover rotating spiral brain waves that travel across cortical networks, acting as a space-and-time clock for ...

For decades, scientists have wondered why specific cells in the brain that control movement fire when people simply plan or imagine making a movement, or observe someone else making a movement - but ...

The classical view of how the human brain controls voluntary movement might not tell the whole story. That map of the primary motor cortex — the motor homunculus — shows how this brain region is ...

Scientists found evidence of two interleaved systems, which may help explain the connection between what's going on in our bodies and what's going on in brain areas involved in thoughts and emotions.

Optogenetics is a recently developed technique that can control cellular functions by illuminating lights to the cells in which light-sensitive proteins are expressed by gene transfer. Optogenetics ...

Scientists have discovered that signals in the motor cortex act like a series of clutches when it comes to moving, and that these signals can be disrupted to slow the brain's initiation of movement.
