Table 1. Number of neurons recorded in each monkey and across various memory periods.

Neurons separated by the number of memory periods in which they are tested (left side, e.g. if a neuron was recorded with objects from two memory periods, it would be counted under column labeled two) and total number of neurons recorded in each memory period (right side, e.g. if a neuron was recorded with objects in days and months memory periods, it would be counted once under each corresponding column)
