The rhythmicity in upper-limb tracking movements and associated population dynamics in primary motor cortex is explained by a feedback controller incorporating optimal state estimation.
The 'Optoclamp' is a feedback control technology that enables precise, continuously updated, closed-loop optical control of neural firing both in vitro and in vivo.
Central vestibular regions in the brainstem and cerebellum perform dynamic Bayesian inference to combine motor commands and sensory signals into an optimal estimate of self-motion.
Down regulation of the gain from the vestibular sensory sources prior to the initiation of movement is a motor control solution to overcome the reflex-stabilizing mechanisms to enable motion from a postural orientation.
Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.
Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.
In the Drosophila central brain, synaptic connectivity extracts visual-spatial information from the axons of looming sensitive LC6 neurons that terminate in a glomerulus with minimal retinotopy.
Neural computations necessary for efficient control of saccades capture the phenomenon of saccadic suppression, which suggests that neural resources are shared for perception and control.
Central thalamus relay neurons dynamically switch the activity of cortical and subcortical networks at distinct frequencies, providing a mechanism for this region's role in arousal regulation.
A brain–computer interface for real-time identification of transient neural activity patterns enables causal inference of the role of these patterns in cognition through closed-loop manipulation.
