Microstimulation in a spiking neural network model of the midbrain superior colliculus
Fig 1
Responses of three SC model neurons to different microstimulation parameters.
The three neurons differed in their adaptation time constants (A: τq = 84.6ms, B: τq = 70.95ms, and C: τq = 52.4ms). Each row shows the membrane potentials, V(t), for the same electrical stimulus, at a particular intensity (see color code for the different lines, top), and delivered at a particular stimulus duration, DS. Note the clear differences in neuronal membrane responses. Stimulus timings and durations are indicated above the traces by black lines, ranging from DS = 25 ms (bottom) to DS = 225 ms (top). Symbols x, o, and +: selected responses, further analyzed in Fig 2.
