Influence
of stimulus intensity and/or a preceding signal on latency and
amplitude of the startle reflex and the auditory cortical evoked
response (ACER) in man
L. Pickenhain & N. Sakano |
If
the acoustic stimulus is preceded by an optic stimulus, the latencies
and amplitudes preceding optic signal elicits a differentiated or
diffuse attention to the acoustic stimulus (pistol-shot or click).
The parallel and inverse changes of the parameters of the startle
blink and the ACER are observed. The differentiated attentive process
reduces the latency and amplitude of the peak N1. In all conditions
there is a positive correlation between the amplitude of the peak
N1 and the subjective startle response (verbal report).
