Amygdalo-hypothalamic projections in the lizard Podarcis hispanica: A combined anterograde and retrograde tracing study
Wiley (1997-08)The cells of origin and terminal fields of the amygdalo-hypothalamic projections in the lizard Podarcis hispanica were determined by using the anterograde and retrograde transport of the tracers, biotinylated dextran amine ... -
Attraction to male pheromones and sexual behaviour show different regulatory mechanisms in female mice
Elsevier (2004-05)In rodents, female sexual behaviour is under hormonal control. The attraction females show for male-derived nonvolatile chemicals (pheromones) can be regarded as the first step of this behaviour, but it is unknown whether ... -
Becoming stressed: Does the age matter? Reviewing the neurobiological and socio-affective effects of stress throughout the lifespan
MDPI (2020-08-13)Social and affective relations occur at every stage of our lives. Impairments in the quality of this “social world” can be exceptionally detrimental and lead to psychopathology or pathological behavior, including ... -
Cladistic Analysis of Olfactory and Vomeronasal Systems
Frontiers (2011-01-26)Most tetrapods possess two nasal organs for detecting chemicals in their environment, which are the sensory detectors of the olfactory and vomeronasal systems. The seventies’ view that the olfactory system was only devoted ... -
Differences in resting-state brain activity metrics related to sensitivity to punishment
Universitat Jaume I (2022-06-17)According to Gray’s revised reward sensitivity theory (Gray & McNaughton, 2000), the scenarios where a person faces an aversive stimulus are mediated by two neurobehavioral systems, the behavioral inhibition system (BIS) ... -
Distribution of calcitonin gene-related peptide-like immunoreactivity in the brain of the lizard Podarcis hispanica
Wiley (2002-05)The present work studies the distribution of calcitonin gene-related peptide-immunoreactive (CGRP-li) neurons and fibers in the brain of a reptile, the lizard Podarcis hispanica. CGRP-li perikarya were not present in the ... -
Distribution of corticotropin-releasing factor-immunoreactive neurons in the central nervous system of the domestic chicken and Japanese quail
Wiley (2004-02)In birds, as in mammals, corticotropin-releasing factor (CRF) is present in a number of extrahypothalamic brain regions, indicating that CRF may play a role in physiological and behavioral responses other than the control ... -
Evolution of vertebrate survival circuits
Elsevier (2018-12)Evolution selects those adaptive features that increase reproductive probabilities and facilitate survival. Analysing the brain circuits mediating risk-avoidance (e.g. defense) and those allowing reward-seeking (motivated) ... -
Inhibition of the medial amygdala disrupts escalated aggression in lactating female mice after repeated exposure to male intruders
Nature Research (2022-09-16)Virgin female laboratory mice readily express pup care when co-housed with dams and pups. However, pup-sensitized virgins fail to express intruder-directed aggression on a single session of testing. To study whether repeated ... -
Involvement of the Nucleus Incertus and Relaxin-3/RXFP3 Signaling System in Explicit and Implicit Memory
Frontiers Media (2021-03-18)Telencephalic cognitive and emotional circuits/functions are strongly modulated by subcortical inputs. The main focus of past research on the nature of this modulation has been on the widespread monoamine projections to ... -
Maternal Motivation: Exploring the Roles of Prolactin and Pup Stimuli
Karger Publishers (2020-07-09)Motherhood entails increased motivation for pups, which become strong reinforcers and guide maternal behaviours. This depends on steroids and lactogens acting on the brain of females during pregnancy and postpartum. Since ... -
Neural activity patterns in the chemosensory network encoding vomeronasal and olfactory information in mice
Frontiers Media (2022)Rodents detect chemical information mainly through the olfactory and vomeronasal systems, which play complementary roles to orchestrate appropriate behavioral responses. To characterize the integration of chemosensory ... -
Relaxin-3 Innervation From the Nucleus Incertus to the Parahippocampal Cortex of the Rat
Frontiers Media (2021)Spatial learning and memory processes depend on anatomical and functional interactions between the hippocampus and the entorhinal cortex. A key neurophysiological component of these processes is hippocampal theta rhythm, ... -
Revisión sistemática sobre las diferencias de volumen y densidad celular de la amígdala entre individuos neurotípicos e individuos con trastorno de espectro autista.
Universitat Jaume I (2020-05-27)Introducción: El trastorno del espectro autista (TEA) es un síndrome caracterizado por alteraciones en el reconocimiento y comportamiento social, atención, interés y comorbilidades como la ansiedad. La amígdala telencefálica ... -
Underlying differences in resting-state activity metrics related to sensitivity to punishment
Elsevier (2023-02-02)Reinforcement sensitivity theory (RST) of personality establishes the punishment sensitivity trait as a source of variation in defensive avoidance/approach behaviors. These individual differences reflect dissimilar sensitivity ... -
Understanding emotions: origins and roles of the amygdala
MDPI (2021-05-31)Emotions arise from activations of specialized neuronal populations in several parts of the cerebral cortex, notably the anterior cingulate, insula, ventromedial prefrontal, and subcortical structures, such as the amygdala, ...
