The LN model approach and the TCS approach represent two distinct ways of characterizing MEC responses. LN method: P = position-encoding cells, H = head direction-encoding cells, S = speed-encoding cells. TCS method: G = grid cells, B = border cells, HV = head direction cells, SC = speed cells. Lines within the chart signify which response profiles are captured by each approach. (See also Figure S1)
