We tend to think of neurons as either excitatory or inhibitory, but some neurons chemically inhibit their downstream targets while electrically exciting their neighbors. What is gained by having an inhibitory neuron excite its neighbor?

Acute Loss of Tactile Input Leads to General Compensatory Changes in Eyeโ€“Hand Coordination during Object Manipulation Current models of motor control emphasize the critical role of sensory feedback, as demonstrated by movement coordination deficits following sensory impairment. When both vision and touch are available for object-oriented manual behaviors, they serve distinct roles; vision guides the execution of planned movements, while touch provides more direct feedback on handโ€“object interactions. The impact of losing somatosensory feedback on eyeโ€“hand coordination during dexterous object manipulation tasks has not been thoroughly studied. Conceivably, vision is recruited to compensate for the feedback lost when touch is abolished based on the dexterity demands of the behavior. To investigate this, we tested healthy participants of either sex on a manual dexterity task requiring the movement of small metal pegs, both before and after the administration of digital anesthesia, which selectively abolished cutaneous sensations in the fingertips while preserving motor function. We recorded participants' gaze and hand positions. Despite loss of cutaneous feedback, participants successfully completed the pegboard task. However, they exhibited significantly longer trial times and altered force profiles. Notably, acute somatosensory loss triggered a rapid shift in visual behavior, characterized by a tighter coupling between gaze and hand positions across all task actions, even those not directly involving object manipulation. These changes, which occurred with anesthesia of the dominant and nondominant hands, were not evident with sham (saline) injections. Our findings underscore the contributions of sensory feedback to force control in service of dexterous object manipulation and reveal the nonselective nature of compensatory gazeโ€“hand coordination processes.

How does the brain decide? ๐Ÿง 

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

We attempt to survey the two different universes of motor learning research: basic (meetings like NCM, MLMC) and applied (e.g. NASPSA), and consider what these fields can learn from each other and what the future might look like if they can be better integrated.

This suggests a previously unrecognized connection between eye movement control and postural reflexes. The findings point to potential links between visual tracking systems and the neural circuits that help maintain balance.

Smooth pursuit eye movements contribute to long-latency reflex modulation in the lower extremity

We investigated how eye movements might influence reflexes during balance tasks. We found that when people tracked a moving object with smooth pursuit versus keeping their gaze fixed, their leg muscle reflexes were enhanced during perturbations.
