Population vector

Definition

The neuronal population vector is the outcome of a computation by which weighted neural activities of individual elements in a population yield an estimate of the population’s functional operation.

Detailed Description

The neuronal population vector is the outcome of a computation. It requires a behavioral measure in multidimensional space, a neuronal population, and an orderly variation of neural activity of the constituent elements in the population with the behavioral measure. The computation is a weighted vectorial sum of neural activities that yields an estimate of the behavioral measure. In the original application (Georgopoulos et al. 1983), the behavioral measure was the direction of arm movement in 2-D space, the neuronal population consisted of cells recorded extracellularly in the monkey motor cortex during movements of different directions, and the orderly variation of neural activity was the directional tuningof rate of firing of...
