Classical approaches to motor systems research (and much of neuroscience) involve measuring the properties of single neurons (Hubel, 1957) and characterizing their responses during complex behaviour. However, with the advent of more sophisticated recording techniques, such as floating microelectrode arrays and optical imaging (O'Shea et al. 2017), we can probe the dynamics of large neural populations by recording thousands, or even 10s of thousands (Pachitariu et al. 2016), of neurons in parallel.
Using these techniques to understand how reaching movements are controlled, we can move away from the neuron doctrine — which posits that the neuron is the functional and perceptual unit of the nervous system, and towards a network view — in which ensembles of distributed neurons form functional units with their own emergent properties.
