Continuous Attractor Network Model for Conjunctive Position-by-Velocity Tuning of Grid Cells

Figure 7

Weight matrix in four dimensional neural space .

Only the slices at of the outgoing weights (A) from and incoming weights (B) to the example unit are shown. (A) The asymmetry in the outgoing weights is determined by the projecting unit (white dot). The triangle marks the unit that is maximally activated among the units in the slice by the projecting unit. (B) The asymmetry in the incoming weights depends on the velocity labels of presynaptic units. Among the unit in the slice, the unit marked by the triangle has the strongest connection to the example unit (white dot).
