Influence
of attention and/or are active motor reaction of the subject on
latency and amplitude of the auditory cortical evoked response
(ACER) in man
N. Sakano & L. Pickenhain |
Changing
the difficulty of a task requiring a decision whether to press a
key or not, the latencies and amplitude of peaks N1 and P2 of the
ACER and the startle reflex were measured. The latencies and amplitudes
of peaks N1 and PZ changed independently, i.e., the peak N1 is correlated
with the attentive process (selective or diffuse), whereas the peak
P2 a correlated with the participation of the motor system which
by instruction is connected with the click.
