Brain-machine-interfaceI requires a set of neurons to change their activity in order to control a cursor on a screen or a robotic arm. Neural activity from the primary motor cortex or the parietal reach region (PRR) is mapped to cursor or robotic arm movements through a decoder. Monkeys can learn to modulate their neural activity to become efficient at that task. In this paper (Hwang et al. 2013), Hwang and colleagues demonstrate that the mod.ulation of neural activity during learning is shaped by the existing neural structure.
