	stimuli applied to mirror sites on both hands or to a similarly timed
	auditory tone. Two stimulus patterns appeared with equal probability

	with a superimposed brief amplitude pulse midway in the trial. Uncued
	stimuli always contained amplitude pulses. Monkeys demonstrated whether
	an amplitude pulse at the cued location was present or absent by
	making appropriately rewarded up and down foot pedal movements. Cue
	location and stimulus pattern varied trial-wise and pseudo-randomly.
	Average firing rates to vibrotactile stimuli in 82 of 181 SII cells
	and 13 of 22 area 7b cells differed significantly during at least
	one epoch for trials cued to the contralateral hand when compared
	to trials cued to the ipsilateral hand or auditory stimulus. Predominant
	were relatively suppressed firing rates during times prior to the
	epoch containing the amplitude pulses or enhanced activity during
	and after these pulses. Generally, different cells showed suppression
	early vs enhancement later in a trial. Analyses of the ratio between
	firing rates before and during the amplitude pulses suggested improved
	evoked signals to the amplitude pulses. The discussion considers
	attention as a mechanism for reducing distractions, early in the
	trial through suppressing these signals, or for selectively increasing
	response magnitudes in the cued channel, especially around times
	when amplitude pulses were present or absent.},
