[PDF][PDF] Ventral hippocampal CA1 and CA3 differentially mediate learned approach-avoidance conflict processing

…, FR Villaruel, A Ussling, S Riaz, ACH Lee, R Ito - Current Biology, 2018 - cell.com
Approach-avoidance conflict arises when an animal encounters a stimulus that is associated
simultaneously with positive and negative valences [1]. The effective resolution of approach…

The rodent medial prefrontal cortex and associated circuits in orchestrating adaptive behavior under variable demands

JG Howland, R Ito, CC Lapish, FR Villaruel - … & Biobehavioral Reviews, 2022 - Elsevier
Emerging evidence implicates rodent medial prefrontal cortex (mPFC) in tasks requiring
adaptation of behavior to changing information from external and internal sources. However, the …

Alcohol-seeking and relapse: A focus on incentive salience and contextual conditioning

MD Valyear, FR Villaruel, N Chaudhri - Behavioural processes, 2017 - Elsevier
Environmental stimuli that reliably accompany alcohol intake can become associated with
the pharmacological effects of alcohol through classical (Pavlovian) conditioning. Of growing …

Optogenetic activation of the infralimbic cortex suppresses the return of appetitive Pavlovian-conditioned responding following extinction

FR Villaruel, F Lacroix, C Sanio, DW Sparks… - Cerebral …, 2018 - academic.oup.com
The infralimbic medial prefrontal cortex (IL) is important for suppressing learned behavior
after extinction, but whether this function extends to responses acquired through appetitive …

[HTML][HTML] Individual differences in the attribution of incentive salience to a Pavlovian alcohol cue

FR Villaruel, N Chaudhri - Frontiers in Behavioral Neuroscience, 2016 - frontiersin.org
Individual differences exist in the attribution of incentive salience to conditioned stimuli
associated with food. Here, we investigated whether individual differences also manifested with a …

Learning processes in relapse to alcohol use: lessons from animal models

MD Valyear, MR LeCocq, A Brown, FR Villaruel… - …, 2023 - Springer
Rationale Alcohol use is reliably preceded by discrete and contextual stimuli which, through
diverse learning processes, acquire the capacity to promote alcohol use and relapse to …

Corticostriatal suppression of appetitive Pavlovian conditioned responding

FR Villaruel, M Martins, N Chaudhri - Journal of Neuroscience, 2022 - Soc Neuroscience
The capacity to suppress learned responses is essential for animals to adapt in dynamic
environments. Extinction is a process by which animals learn to suppress conditioned …

Neural correlates of recall and extinction in a rat model of appetitive Pavlovian conditioning

A Brown, FR Villaruel, N Chaudhri - Behavioural Brain Research, 2023 - Elsevier
Extinction is a fundamental form of inhibitory learning that is important for adapting to
changing environmental contingencies. While numerous studies have investigated the neural …

Augmenting glutamatergic, but not dopaminergic, activity in the nucleus accumbens shell disrupts responding to a discrete alcohol cue in an alcohol context

…, A Brown, G Deyab, FR Villaruel… - European Journal of …, 2024 - Wiley Online Library
Discrete alcohol cues and contexts are relapse triggers for people with alcohol use disorder
exerting particularly powerful control over behaviour when they co‐occur. Here, we …

Neural correlates of extinction in a rat model of appetitive Pavlovian conditioning

A Brown, FR Villaruel, N Chaudhri - bioRxiv, 2022 - biorxiv.org
Extinction is a fundamental form of inhibitory learning that is important for adapting to
changing environmental contingencies. While numerous studies have investigated the neural …
