CHAPTER 1
| INTRODUCTION
The ENV-250S Switch is offered as an alternative to the ENV-250A. The ENV-250A is a complete
lickometer unit that will also switch a direct aversive stimulation output to the sipper tube
spout. The ENV-250S Switch does not include the lickometer amplifier and must be used with
one of the standard contact lickometer controllers, ENV-250, ENV-250B or ENV-250C. It will
switch each of the nine leads of the grid harness between the lickometer amplifier and the nine
outputs of the ENV-412 Scrambler. This permits the delivery of scrambled foot aversive
stimulation with any of the three lickometer controllers listed. Lick data collection is
momentarily interrupted during aversive stimulation delivery. For continuous data collection
during aversive stimulation delivery it would be necessary to use one of the photobeam
lickometers (ENV-251L or ENV-251M).
