Acute and Long-Term Effects of Noise Exposure on the Neuronal Spontaneous Activity in Cochlear Nucleus and Inferior Colliculus Brain Slices

Figure 2

Example of filtered and amplified spike trains of DCN neurons from a control (a) and a 14-day group (b) animal, recorded with the spike2 software. Single units were classified using the template matching function of the spike2 software and mean spontaneous activity was calculated accordingly from the original recordings. Each diagram represents a one-second frame out of a 3-minute recording with the time in seconds on the -axis and the activity in volt on the -axis. The higher spike rate of the 14-day group neuron indicates the increase in spontaneous firing in the noise-exposed group two weeks after trauma.
