[PDF][PDF] Ventral hippocampal CA1 and CA3 differentially mediate learned approach-avoidance conflict processing
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
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
Environmental stimuli that reliably accompany alcohol intake can become associated with
the pharmacological effects of alcohol through classical (Pavlovian) conditioning. Of growing …

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