nervous system
• prior to and after the onset of hearing, mice exhibit reduced rate of recovery of the fast releasing synaptic vesicle pool in the calyx of Held compared with wild-type mice
• after the onset of hearing, mice exhibit reduced rate of recovery of the fast and slow releasing synaptic vesicle pool in the calyx of Held compared with wild-type mice
• slower recovery after excitatory postsynaptic currents depression, more pronounced after 300 Hz trains
• after the onset of hearing, mice exhibit aberrant short-term synaptic depression in the calyx of Held compared with wild-type mice
• however, short-term depression prior to the onset of hearing is normal
