From: Spatiotemporal dynamics in spiking simulations of superior colliculus fit via MCMC suggest disinhibition responsible for superlinear summation

Figure 1

(A) Experimental setup of [1], showing slice containing excitatory (red) and inhibitory (gray) neurons. Stimulation applied to electrodes at lateral distances while recording from an excitatory neuron. (B) Empirical results (dotted) and model fits. Purple: repetitive stimulation single point, Red: repetitive stimulation two point. (C) Example of a dynamics plot, in this case Inhib→Excit, showing net conductance in circuit as a function of sending and receiving neuron. (D) Difference between dynamics plots. Two-point stimulation minus the linear sum of two single-point stimulation conditions, showing where and when non-linear changes in activity occur.
