Classical conditioning of the eyelid reflex has been used for a long time to study associative learning in animals and humans. A new experimental procedure for rabbit?s eyelid conditioning was constructed and described. A phonopneumatic stimulator generated conditioned and unconditioned stimuli and a photoelectric transducer acting in close infrared converted movements of rabbits? eyelid to electric signals. An example of acquisition and extinction training is illustrated. This method of eyelid movement monitoring is noninvasive. It may be useful for chronic studies of learning processes in rabbits when used with headpieces for microdialysis probes, electrodes or cannulas which could be implanted into brain structures

Influence of thyrotropin-releasing hormone (TRH) dialyzed into the hippocampus on memory processes in rabbit

There are conflicting reports on the influence of thyrotropin-releasing hormone (TRH) on the process of learning. We decided to study this problem using the paradigm of classical eyeblink conditioning as the animal model of learning processes. During the extinction training TRH in its natural form of pGluTRH was applied into the rabbit hippocampus through a chronically implanted microdialysis probe. A Glu1TRH, analog with less biological potency than TRH as the control of specificity for TRH and a 0.9% NaCl solution as the control for both substances were applied by the same way as pGluTRH. We found that pGluTRH extended the process of extinction and enhanced the further acquisition of the reflex. The analog of TRH, Glu1TRH, was ineffective. Finally, it may be stated that TRH acting in the hippocampus prolonged process of forgetting and improved succeeding learning. The effect was specific and long lasting.
