Amygdaloid projections to the ventral striatum in mice: direct and indirect chemosensory inputs to the brain reward system
Frontiers (2011-08-22)Rodents constitute good models for studying the neural basis of sociosexual behavior. Recent findings in mice have revealed the molecular identity of the some pheromonal molecules triggering intersexual attraction. However, ... -
Efecto de la modulación dopaminérgica en la preferencia por reforzadores activos en ratones con una mutación en el factor de transcripción Pitx3
Publicacions de la Universitat Jaume I. Servei de Comunicació i Publicacions (2022)La conducta motivada está caracterizada por altos niveles de activación, vigor y persistencia. La dopamina del núcleo accumbens (nacb) está implicada en regular este componente energizante de la motivación, incluida la ... -
Effect of repeated administration of a dopaminergic precursor on the preference for active reinforces in Pitx3-aphakia KO mice of both sexes
Universitat Jaume I (2022-06-17)Motivated behavior is characterized by high levels of activation, vigor and persistence. Effort-related decision-making is regulated by dopamine (DA) in the nucleus accumbens (Acc). The transcription factor Pitx3 is required ... -
Energizing effects of bupropion on effortful behaviors in mice under positive and negative test conditions: modulation of DARPP-32 phosphorylation patterns
Springer (2021-09-09)Motivational symptoms such as anergia, fatigue, and reduced exertion of effort are seen in depressed people. To model this, nucleus accumbens (Nacb) dopamine (DA) depletions are used to induce a low-effort bias in rodents ... -
Hippocampal dopamine receptors modulate cFos expression in the rat nucleus accumbens evoked by chemical stimulation of the ventral hippocampus
Elsevier (2005-12)Recently, we have shown that D1 and D2 receptors in the ventral hippocampus (VH) modulate both the locomotor activation and the increase in dopamine (DA) levels in the rat nucleus accumbens (NAc) induced by NMDA stimulation ... -
Neural correlates of cocaine-induced conditioned place preference in the posterior cerebellar cortex
Frontiers Media (2023)Introduction: Addictive drugs are potent neuropharmacological agents capable of inducing long-lasting changes in learning and memory neurocircuitry. With repeated use, contexts and cues associated with consumption can ... -
The Neurobiology of Activational Aspects of Motivation: Exertion of Effort, Effort-Based Decision Making, and the Role of Dopamine
Annual Reviews (2024)Motivational processes are complex and multifaceted, with both directional and activational aspects. Behavioral activation and exertion of effort are functions that enable organisms to overcome obstacles separating them ...
