We measured in WT and PACAP-deficient mice the hearing thresholds, amplitudes and latencies of auditory brainstem responses ABRs ; quantified the neuronal activation in the nuclei of the auditory pathway after acoustic stimulation; and performed proteome profile analysis of cochlear duct lysates to explore the molecular mechanisms of the impairing effect of endogenous PACAP deficiency on hearing. Cells with well-defined nuclei and nucleoli were counted to exclude glial cells from the measurement. Neuroreport 14—8 WT values at the corresponding stimulus frequency. Figure 7.

The outer bony wall of the cochlea was removed and the apical part of the cochlear duct was separated from the modiolus. In mice and humans alike, sound-evoked potentials from the auditory brainstem appear as a series of consecutive peaks and valleys of ABR waves. Lajko, A.
Deafness and hearing loss Causes, symptoms, and treatments
Peptides 6651—7 We assume that there is a greater possibility for this compensation in the central nuclei of the auditory pathway as those obtain more complex connection patterns with several neuronal types releasing numerous neurotransmitters in these areas. For publication purposes, representative images were contrasted and in some cases the brightness was adjusted to correct the uneven illumination in peripheral areas.
