Fig 9. Inhibition in L4 controls the response to L4E neurons.

(a-c) Changing g_IE from 0 to 1.2 mS/cm² (d-f) Changing g_EI from 0 to 1.4 mS/cm². (g-i) Changing g_II from 0 to 1.1 mS/cm². In the top panels, the synaptic connection that its strength is varied is plotted in green. In the middle and bottom panels, curves are plotted for 11 values of the relevant g from 0 (light green) to its maximal value, that is twice the reference parameter value (dark green). (b, e, h) The response of L4E neurons, ν_E, to slowly varying thalamic input, which correlates with the amplitude of whisking. (c, f, i) The response of L4E neurons to spikes, R_E, associated with touch.
