Rewarding effects of the electrical stimulation of the parabrachial complex: Taste or place preference? Simón Ferre, María José García, Raquel Puerto, Amadeo The lateral parabrachial complex has been related to various emotional-affective processes. It has been shown that electrical stimulation of the external Lateral Parabrachial (LPBe) nucleus can induce reinforcing effects in place preference and taste discrimination tasks but does not appear to support self-stimulation. This study examined the relative relevance of place and taste stimuli after electrical stimulation of the LPBe nucleus. A learning discrimination task was conducted that simultaneously included both sensory indexes (taste and place) in order to determine the preference of animals for one or the other. After a taste stimulus reversal task, the rewarding effect of stimulation was found to be preferentially associated with place. These results are discussed in the context of the rewarding action and biological constraints induced by different natural and artificial reinforcing agents. 2025-02-26T06:55:32Z 2025-02-26T06:55:32Z 2014-01 journal article Neurobiology of Learning and Memory 107:101-7 https://hdl.handle.net/10481/102685 10.1016/j.nlm.2013.11.010 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
