Parvalbumin immunoreactivity in the auditory cortex of a mouse model of presbycusis.

Abstract

Age-related hearing loss (presbycusis) affects ∼35% of humans older than sixty-five years. Symptoms of presbycusis include impaired discrimination of sounds with fast temporal features, such as those present in speech. Such symptoms likely arise because of central auditory system plasticity, but the underlying components are incompletely characterized. The rapid spiking inhibitory interneurons that co-express the calcium binding protein Parvalbumin (PV) are involved in shaping neural responses to fast spectrotemporal modulations. Here, we examined cortical PV expression in the C57bl/6 (C57) mouse, a strain commonly studied as a presbycusis model. We examined if PV expression showed auditory cortical field- and layer-specific susceptibilities with age. The percentage of PV-expressing cells relative to Nissl-stained cells was counted in the anterior auditory field (AAF) and primary auditory cortex (A1) in three age groups: young (1-2 months), middle-aged (6-8 months) and old (14-20 months). There were significant declines in the percentage of cells expressing PV at a detectable level in layers I-IV of both A1 and AAF in the old mice compared to young mice. In layers V-VI, there was an increase in the percentage of PV-expressing cells in the AAF of the old group. There were no changes in percentage of PV-expressing cells in layers V-VI of A1. These data suggest cortical layer(s)- and field-specific susceptibility of PV+ cells with presbycusis. The results are consistent with the hypothesis that a decline in inhibitory neurotransmission, particularly in the superficial cortical layers, occurs with presbycusis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
