Auditory Brainstem Response (ABR) measurement for Akt2tm1e(KOMP)WtsiMGP Pipeline 2
Results Summary
ABR thresholds normal
Methods Summary
Auditory Brainstem Responses (ABRs) are recorded via subcutaneous needle electrodes placed at the vertex and behind the left ear, as an average of 256 responses to presentation of freefield stimuli [clicks (10us) or tone pips (5ms tone pips, 1ms rise/fall time)], presented at 42.2/sec.
ABR Thresholds are determined and plotted as a function of stimulus. Mean Threshold is plotted (+/- population standard deviation). The green shaded area indicates the mean threshold (+/- 1SD and +/- 2SD) of a large population of wildtype mice of this genetic background.
Click-Evoked ABRs waveforms were analysed. Amplitudes and Latencies for waves P1, N1, P3 and N3 were recorded and are plotted as a function of absolute sound pressure level (SPL) and SPL relative to threshold. Means are plotted (+/- population standard deviation).
