Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.

A novel motor task reveals the principle of how the motor system coordinates the redundant body for motor adaptation.

Humans retrospectively localize touch after deciding on which limb it occurred, challenging the mainstream idea that tactile location in space is the basis for assigning touch to a body part.

An electrode-wise encoding model based on physiological recordings from the cortical surface revealed a striking hemispheric asymmetry where the encoding of ipsilateral movement was stronger in the left hemisphere compared to the right hemisphere.

An energetic cost related to force rate is quantified in human arm movements, and minimizing this cost predicts smoothness without minimizing variance, unifies motor-planning of smoothness and movement duration, and may help resolve motor redundancies.

When making two decisions about one object, two streams of information can be acquired in parallel but must be incorporated into the two decisions serially, consistent with a central bottleneck.

The brain continuously updates the learned temporal relationship between motor commands and their associated somatosensory feedback, which determines the perceived intensity and ticklishness of self-touch.

Neural recordings demonstrate how information about the contralateral limb can be isolated from the ipsilateral limb in motor cortex.

The brain continues to represent individual fingers in primary somatosensory cortex decades after the amputation of a hand, indicating that cortical maps do not require ongoing sensory input from the body.

Brain imaging reveals frequency-dependent lateralized rhythmic finger tapping control by the auditory cortex with left-lateralized control of relative fast and right-lateralized control of relative slow rhythms.
