In neuroscience, a population vector is the sum of the preferred directions of a population of neurons, weighted by the respective spike counts.
The formula for computing the (normalized) population vector, takes the following form:
Where is the activity of cell, and is the preferred input for cell .
Note that the vector encodes the input direction, in terms of the activation of a population of neurons.
Famous quotes containing the word population:
“A multitude of little superfluous precautions engender here a population of deputies and sub-officials, each of whom acquits himself with an air of importance and a rigorous precision, which seemed to say, though everything is done with much silence, “Make way, I am one of the members of the grand machine of state.””
—Marquis De Custine (1790–1857)
