Cortical reorganization produces an interhemispheric asymmetry in auditory evoked brain potentials associated with sound stimulation after unilateral implantation.
Under these one-dimensional assumptions, the data of Fig. 7 indicate that Deiters' cells change length (cyclically) during sound stimulation by ~2× as much as OHCs do.
This is a model of neurons in the brainstem superior paraolivary nucleus (SPN), which produce very salient offset firing during sound stimulation.
To study when and how such rhythm emerges in infancy, we examined electroencephalogram (EEG) recordings in infants 4 and 12 months of age during sound stimulation and silence.
We validated sound stimulation via the headphones in ferrets trained previously in a free-field task to localize stimuli presented from one of two loudspeakers.
We designed a set of devices for generating sound fields and studied the effect of sound stimulation on Dendranthema morifolium callus growth.
We came to a conclusion that the promotion effect was most obvious in a frequency of 1000 Hz and a strength of 100 dB sound stimulation.
It was found in our experiment that sound stimulation of a frequency of 1000 Hz and a strength of 100 dB obvious promoted the soluble protein and sugar in cytoplast, which is a sigh of high metabolism level and vigorous divide state in strong sound stimulation administrated D. morifolium callus.
c, The mice exposed to the combined light and sound stimulation had strengthened excitatory neural connections (blue arrows) in the brain between the superior colliculus and the mediodorsal thalamus, and between the mediodorsal thalamus and the basolateral amygdala.
Furthermore, the comparison of the hemodynamic response of the most anterior and the posterior clusters of activation highlighted differential response patterns to the sound stimulation and to the EPI-noise.
In this arrangement the discontinuity is between the air of the swim bladder and the chain of ossicles in contact with it; the relative motion arising from sound stimulation is communicated through the ossicular (bony) chain and the fluid channels to the macular endings.
