In noise the onset response to the stop consonant /d/ was reduced or eliminated at each level, to the greatest degree in primary auditory cortex.
Results indicate that noise-exposed auditory-nerve fibers show significantly reduced response latency, increased onset response and percent adaptation, faster adaptation after onset, and slower recovery after offset.
The pitch onset response (POR) evoked by the transition between two regular interval sounds (RIS) with different pitch was studied by recording the neuromagnetic responses with a 122-channel whole head magnetoencephalograph (MEG).
The gene expression data confirmed a strong Type 2 response to T. suis (e.g. marked increase in IL-13, ARG1 and CCL11) and clearly weaker in amplitude and/or delayed onset response to O. dentatum in the single infected group.
This contrasts with hypotheses that either delta and theta reflect their corresponding linguistic levels of analysis or each band is part of a single holistic onset response that tracks global acoustic transitions in the speech stream.
The onset responses were analyzed by computing the RMS amplitude of the onset response peaks.
Interestingly, for coincidences to become relevant, synaptic depression is a necessary ingredient, especially after the temporally more precise onset response.
The HGB onset response was found to be absent, or markedly attenuated during the SV block (Fig. 3B).
Interestingly, the RF onset response was rectified and did not occur at the end of the voltage command step.
