Lateral septum stimulation disinhibits dopaminergic neurons in the antero-ventral region of the ventral tegmental area: Role of GABA-A alpha 1 receptors
(2018)
The mechanisms commanding the activity of dopaminergic neurons of the ventral tegmental area (VTA) and the location of these neurons are relevant for the coding and expression of motivated behavior associated to reward-related ...
Organization of ventral tegmental area projections to the ventral tegmental area-nigral complex in the rat
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The ventral tegmental area (VTA) is a nodal link in reward circuitry. Based on its striatal output, it has been subdivided in a caudomedial part which targets the ventromedial striatum, and a lateral part which targets the ...
Exposure to repeated immobilization stress inhibits cocaine-induced increase in dopamine extracellular levels in the rat ventral tegmental area
(2015)
A higher vulnerability to drug abuse has been observed in human studies of individuals exposed to chronic or persistent stress, as well as in animal models of drug abuse. Here, we explored the effect of repeated immobilization ...
Ghrelin Recruits Specific Subsets of Dopamine and GABA Neurons of Different Ventral Tegmental Area Sub-nuclei
(Pergamon-Elsevier Science Ltd, 2018-11)
Ghrelin is a stomach-derived hormone that regulates rewarding behaviors and reinforcement by acting on the ventral tegmental area (VTA). The VTA is a complex midbrain structure mainly comprised of dopamine (DA) and ...
Prevention of social stress-escalated cocaine self-administration by CRF-R1 antagonist in the rat VTA
(Springer, 2011-11-01)
Intermittent exposure to social defeat stress can induce long-term neural plasticity that may influence escalated cocaine-taking behavior. Stressful encounters can lead to activation of dopamine neurons in the ventral ...
Prevention of social stress-escalated cocaine self-administration by CRF-R1 antagonist in the rat VTA
(Springer, 2011-11-01)
Intermittent exposure to social defeat stress can induce long-term neural plasticity that may influence escalated cocaine-taking behavior. Stressful encounters can lead to activation of dopamine neurons in the ventral ...
Relationship between the afferent innervation pattern and the spontaneous and aversive stimulus driven activity of individual vta dopaminergic neuronsRelación entre el patrón de inervación aferente, la actividad espontánea y en respuesta a un estímulo aversivo en neuronas individuales dopaminérgicas del VTA
(2019)
Activity of ventral tegmental area (VTA) dopaminergic (DA) neurons has been involved in memory, behavioral reinforcement and motivation and also in several neural disorders such as drug addiction, attention deficit ...
Relationship between the afferent innervation pattern and the spontaneous and aversive stimulus driven activity of individual VTA dopaminergic neurons.
(2019)
Ventral tegmental area (VTA) dopaminergic (DA) neurons have been implicated in several
brain functions such as attention, memory, behavioral reinforcement and motivation. Dysfunction
of these neurons has been associated ...
Dopamine Neurotransmission in the Ventral Tegmental Area Promotes Active Forgetting of Cocaine-Associated Memory
(Humana Press, 2019-09)
Dopamine (DA) neurons in the ventral tegmental area (VTA) are well-known components of the brain involved in reward-related behaviors and participate in the generation of new memories. Much attention has been focused to ...
Corticotropin-releasing factor type-2 receptor and corticotropin-releasing factor-binding protein coexist in rat ventral tegmental area nerve terminals originated in the lateral hypothalamic area
(2016)
There is significant functional evidence showing that corticotropin-releasing factor type-2 receptor (CRF2R) and corticotropin-releasing factor-binding protein (CRF-BP) regulate glutamatergic synapses onto ventral tegmental ...
