Topic: delayed reach

Prevalent dynamical systems view posits that cortical preparatory activity seeds temporal evolution to generate movement, but it remains unclear the neural computation that preparatory activity develops to initialize movements in dynamic sensorimotor contingency, such as interception of motion targets. In the present study, we analyzed neural population dynamics recorded from motor cortex via Utah array while two macaques performed a delayed reach toward a target either static or moving circularly. Principal component analysis (PCA) showed that the directional tuning of preparatory latent fact
