Paraventricular thalamus mediates context-induced reinstatement (renewal) of extinguished reward seeking.
Paraventricular thalamus (PvTh) is uniquely placed to contribute to reinstatement of drug and reward seeking. It projects extensively to regions implicated in reinstatement including accumbens shell (AcbSh), prefrontal cortex (PFC) and basolateral amygdala (BLA), and receives afferents from other regions important for reinstatement such as lateral hypothalamus. We used complementary neuroanatom...
متن کاملCocaine- and Amphetamine-Regulated Transcript (CART) Signaling within the Paraventricular Thalamus Modulates Cocaine-Seeking Behaviour
BACKGROUND Cocaine- and amphetamine-regulated transcript (CART) has been demonstrated to play a role in regulating the rewarding and reinforcing effects of various drugs of abuse. A recent study demonstrated that i.c.v. administration of CART negatively modulates reinstatement of alcohol seeking, however, the site(s) of action remains unclear. We investigated the paraventricular thalamus (PVT) ...
متن کاملCritical role for the mediodorsal thalamus in permitting rapid reward-guided updating in stochastic reward environments
Adaptive decision-making uses information gained when exploring alternative options to decide whether to update the current choice strategy. Magnocellular mediodorsal thalamus (MDmc) supports adaptive decision-making, but its causal contribution is not well understood. Monkeys with excitotoxic MDmc damage were tested on probabilistic three-choice decision-making tasks. They could learn and trac...
متن کاملProjections of the paraventricular and paratenial nuclei of the dorsal midline thalamus in the rat.
The paraventricular (PV) and paratenial (PT) nuclei are prominent cell groups of the midline thalamus. To our knowledge, only a single early report has examined PV projections and no previous study has comprehensively analyzed PT projections. By using the anterograde anatomical tracer, Phaseolus vulgaris leucoagglutinin, and the retrograde tracer, FluoroGold, we examined the efferent projection...
متن کاملThe anterior paraventricular thalamus modulates neuronal excitability in the suprachiasmatic nuclei of the rat.
The suprachiasmatic nucleus (SCN) in mammals is the master clock which regulates circadian rhythms. Neural activity of SCN neurons is synchronized to external light through the retinohypothalamic tract (RHT). The paraventricular thalamic nucleus (PVT) is a neural structure that receives synaptic inputs from, and projects back to, the SCN. Lesioning the anterior PVT (aPVT) modifies the behaviora...
