There is growing evidence that estradiol (E2) enhances fear extinction memory consolidation. However, it unclear how E2 influences the nodes of network to enhance memory. This study begins delineate neural circuits underlying influence on acquisition and consolidation in female rats. After conditioning (day 1), naturally cycling rats underwent learning 2) a low‐E2 state, receiving systemic administration either or vehicle prior training. Extinction recall was then tested 24 hr later 3). We...
Glutamatergic projections of the thalamic rostral intralaminar nuclei thalamus (rILN) innervate dorsal striatum (DS) and are implicated in dopamine (DA)-dependent incubation drug seeking. However, mechanism by which rILN signaling modulates reward seeking striatal DA release is unknown. We find that activation inputs to DS drives cholinergic interneuron burst-firing behavior D2 receptor-dependent post-burst pauses firing. In vivo, optogenetic this pathway reinforcement a D1 manner,...
The basal ganglia play a key role in visual perceptual decisions. Despite being the primary target for inputs from cortex, posterior striatum′s (PS) involvement behavior remains unknown rodents. We reveal that PS direct pathway is largely segregated dorsomedial striatum (DMS) pathway, other major striatal cortex. investigated of decisions by optogenetically stimulating medium spiny neurons (D1-MSNs) mice performing change-detection task. D1-MSN activation robustly biased manner dependent on...
Extinction of conditioned fear has been extensively studied in male rodents. Recently, there have an increasing number studies indicating that neural mechanisms for certain behavioral tasks and response behaviors are different females males. Using research can represent a challenge because the variation gonadal hormones during their estrous cycle. This protocol describes well-established procedures useful investigating role estrogen extinction memory consolidation female rats. Phase cycle...
Substance use disorder is a chronic disease and leading cause of disability around the world. The NAc major brain hub mediating reward behavior. Studies demonstrate exposure to cocaine associated with molecular functional imbalance in medium spiny neuron subtypes (MSNs), dopamine receptor 1 2 enriched D1-MSNs D2-MSNs. We previously reported repeated induced transcription factor early growth response 3 ( Egr3 ) mRNA D1-MSNs, reduced it Here, we report our findings male mice inducing MSN...
The dorsal striatum (DS) mediates the selection of actions for reward acquisition necessary survival. Striatal pathology contributes to several neuropsychiatric conditions, including aberrant specific rewards in addiction. A major source glutamate driving striatal activity is rostral intralaminar nuclei (rILN) thalamus. Yet, information that relayed support action unknown. Here, we discovered rILN neurons projecting DS are innervated by a range cortical and subcortical afferents rILN→DS...

Abstract Substance use disorder is a debilitating chronic disease and leading cause of disability around the world. The nucleus accumbens (NAc) major brain hub that mediates reward behavior. Studies demonstrate exposure to cocaine associated with molecular functional imbalance in two NAc medium spiny neuron subtypes (MSNs), dopamine receptor 1 2 enriched D1-MSNs D2-MSNs. Our previous reports showed repeated induced transcription factor early growth response 3 (Egr3) mRNA D1-MSNs, while...

A major source glutamate driving striatal activity is rostral intralaminar nuclei thalamus (rILN). Yet, information that relayed support action unknown.
