PINTO, J. A.  and  BECERRA, S. A.. Bilateral discrimination of the eyeblink conditioned response in humans. Rev Arg Cs Comp. [online]. 2019, vol.11, n.1, pp.9-15.  Epub Feb 25, 2019. ISSN 1852-4206.

The present investigation aims to determine if the conditioned response of eyeblink is lateralized in humans. For this an experiment was carried out, where the participants received a total of 132 tests consisting of the presentation of auditory stimuli and vibrations, of which 66 trials corresponded to the conditioned stimulus (CS+) associated with an air puff as unconditioned stimulus (US), alternated with 66 tests of the conditioned stimulus (CS-) only. The responses were measured both to the eye that received stimulation (ipsilateral) and to the one that did not receive it (contralateral) during the course of training. The results showed that the responses are bilateral, which would not allow separating the sensory effects of the emotional ones in an CS-US association.

Keywords : conditioning; eyeblink response; sensory responses; emotional responses.
