Neurons in the Motor Cortex Are Broadly Tuned and Show

question 1

Essay

Neurons in the motor cortex are broadly tuned and show selectivity for a direction of movement. There is evidence that movement is coded by the activity of a population of neurons. One of the experiments that provided evidence for this used a multi-electrode array. Why is this a good method for studying this type of coding and why would a local field potential or intracellular recording not have provided the evidence needed to show a population code?
