Investigation of Neuron Latency Modulated by Bilateral Inferior Collicular Interactions Using Whole-Cell Patch Clamp Recording in Brain Slices

Figure 4

Variation in response latency in recording neurons under current strength step after induction of synaptic input from the contralateral IC. (a) Variation in the mean latency in 16 neurons exhibiting shortened latency under current strength that was above threshold. indicates the number of neurons. (b) The variation in the mean latency in 24 neurons that exhibited prolonged latency under current strength that was above threshold. indicates the number of neurons. (c) The variation in the mean latency in 13 neurons that did not exhibit any change in latency under current strength that was above threshold. indicates the number of neurons. In (a–c), the black line represents the mean latency of the control group under current strength that was above threshold. The red line represents the mean latency under current strength that was above threshold when the synaptic input from the contralateral IC neuron was induced. The green line indicates the mean latency under current strength that was above threshold in recovery. The response latency after or before stimulation was analyzed statistically. ; ; (paired -tests).
