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, F , takes the following form: F = \frac{\sum_j m_j F_j}{\sum_j m_j} Where m_j is the activity of cell j , and F_j is the preferred input for cell j . Note that the vector F encodes the input direction, F_j , in terms of the activation of a population of neurons.
