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:
“It was a time of madness, the sort of mad-hysteria that always presages war. There seems to be nothing left but warwhen any population in any sort of a nation gets violently angry, civilization falls down and religion forsakes its hold on the consciences of human kind in such times of public madness.”
—Rebecca Latimer Felton (18351930)
