Abstract: The EVOKE program was designed to collect volume
conducted brain stem potentials evoked by auditory
stimuli. Responses are collected over a 30 msec time
frame, 5 msec pre and 25 msec post stimulus. Sampling is
at 10,000 samples/sec. Summed activity is displayed on
line using an oscilloscope and offline on a VT105. Four
runs are maintained active on the system and can be
manipulated using routines for add, subtract, point
smooth, cross correlate and z score transform. Hard copy
plotting is contained in a subroutine which is passed to
the data array. Sampling rate, A/D-D/A address, and
numbers of samples/run are easily modifyable in the
MACRO routine.
 
Notes: Developed on MINC-11, applicable to other PDP-11
systems.
