Motor control refers to the process by which the nervous system coordinates the muscle and limbs to achieve a desired movement or set of actions. This includes the ability to anticipate, adjust and respond to deviations from the desired action.
This study proposes a spiking neural attractor model with robust winnerless competition, that can perform action selection and reproduce the context dependent dynamic modulation of neuronal and behavioral variability, as analyzed in two behaving monkeys.
Advanced sensory feedback from upper limb prostheses would provide multiple benefits to people with upper limb amputations, but achieving functional and natural-feeling sensation is technologically challenging. Advances are being made with invasive and non-invasive stimulation approaches, but considerable challenges need to be addressed with technological innovation.
Prosthetic embodiment, or the incorporation of a prosthesis into one’s sensory and functional body schema, may be achieved by engineering bionic limbs that leverage a closed-loop mechanoneural–machine interface. However, the subjective experience of embodiment remains difficult to define and assess.
The main direction of motor skill-specific information between rat primary motor cortex and dorsolateral striatum is shown to switch from cortex-predominant before learning to striatum-predominant after learning.
