The central nucleus of the amygdala (CeA) is considered to be involved in different affective, sensory, regulatory, and acquisition processes. This study analyzed whether electrical stimulation of the PB-CeA system induces preferences in a concurrent place preference (cPP) task, as observed after stimulation of the parabrachial-insular cortex (PB-IC) axis.(More)
The role of opiate systems has been extensively studied in relation to learning and memory. Naloxone (Nx), an opiate antagonist, was administrated in concurrent (Experiment 1) and sequential (Experiment 2) flavor aversion learning (FAL) tasks. The outcomes demonstrate that Nx impairs the acquisition of concurrent but not sequential FAL. In the concurrent(More)
Sensory information from the gastrointestinal system can be transmitted to the brain through the vagus nerve, the intermediate-caudal region of the nucleus of the solitary tract (NST), and various subnuclei of the parabrachial complex, notably the external lateral subnucleus (LPBe). The objective of the present study was to examine the relevance of this(More)
Marine organisms in Antarctica are adapted to an extreme ecosystem including extremely stable temperatures and strong seasonality due to changes in day length. It is now largely accepted that Southern Ocean organisms are particularly vulnerable to global warming with some regions already being challenged by a rapid increase of temperature. Climate change(More)
The amygdala is considered a crucial brain nucleus in different modalities of aversive conditioning, including flavor aversion learning (FAL). The importance attributed to the amygdala and its subnuclei has frequently depended on the different stimuli and procedures used in FAL tasks. In this study, FAL was impaired only in animals that had lesions in the(More)
The Register of Antarctic Marine Species (RAMS) is a marine species database that manages an authoritative taxonomic list of species occurring in the Southern Ocean. RAMS links with several other initiatives managing biogeographic or genomics information. The current paper aims to briefly present RAMS and provides an updated snapshot of its contents, in the(More)
