UC San Diego researchers discovered that during motor learning, inputs from the motor thalamus play a crucial role in ...

However, the failure of rTMS to interfere with M1 excitability and with early motor consolidation if applied to the dorsolateral prefrontal cortex and ... was the primary outcome measure.

In addition, the study shows that “while M1 [primary motor cortex] may code for limb movement planned by parietal systems, only activity in the latter (but not the former) may mediate conscious ...

For many years, neuroscientists have isolated the brain's primary motor cortex (M1), an area in the frontal lobe region, as a hub for sending out signals related to complex movements during ...

In the latest shift in our view of the brain’s organization, researchers from the Gordon Neuroimaging Lab at Washington University School of Medicine, St. Louis added previously unidentified areas to ...

A landmark study published by scientists at the University of California San Diego is redefining science's understanding of the way learning takes ...

including the secondary somatosensory cortex (S2), the primary motor cortex (M1), and the sensory thalamus (TLM). To investigate how these regions modulate activity in S1, the researchers turned ...

Phototactile' hand stimulation rapidly activates first the somatosensory then the motor cortex, broadly consistent with constraints suggested by the previously described circuit architecture of this ...

Contrastingly, non-human primate (NHP) studies divided M1 into anterior and posterior ... to the homotopic contralateral motor cortex and the adjacent primary somatosensory cortex.
