Visual Salience Controls the Speed of Evidence Accumulation in Value-Based Decisions by Rats

This study shows that visual salience affects decision speed in rats, with intermediate salience cues reducing choice preference and slowing evidence accumulation.

Active Sampling and Sex Differences in Perceptual Decision Making in Rats

This study examines sex differences in perceptual decision making in rats, finding that females sample longer and show a negative association between sampling duration and drift rate.

Learning to Choose: Behavioral Dynamics Underlying the Initial Acquisition of Decision Making

This study investigates how decision-making evolves during initial learning in rats, finding that choice performance improves with experience while response slowing persists.

The role of rat prelimbic cortex in decision making

This study investigates the role of the rat prelimbic cortex in decision-making, finding it influences decision thresholds and reveals sex-based differences in learning.

An ancient subcortical circuit decides when to orient to threat in humans

The paper identifies a subcortical circuit involved in switching between threat vigilance and reward foraging in humans using fMRI.

The rostral medial frontal cortex is crucial for engagement in consummatory behavior

This study investigates the role of rostral medial frontal cortex in consummatory behavior using reversible inactivation and opioid receptor stimulation in rats.

Noradrenergic Regulation of Two-Armed Bandit Performance

This study investigates how noradrenergic system perturbations affect reversal learning by using a block-based reversal design, finding that choice accuracy is independent of win-stay behavior and noradrenergic control influences sensitivity to positive feedback.

Coherent theta activity in the medial and orbital frontal cortices encodes reward value

This study shows that theta rhythms in medial and orbital frontal cortices track reward magnitude and value during consumption, with MFC showing stronger coupling and top-down control.

An open source platform for presenting dynamic visual stimuli

The paper describes an open-source, low-cost platform for presenting dynamic visual stimuli in operant behavior experiments, demonstrating its use in training rats to discriminate visual cues.

Medial frontal theta is entrained to rewarded actions

The paper investigates how reward value is encoded by medial frontal cortex theta rhythms in rats during licking tasks, finding that theta rhythms are synchronized with rewarded actions and persist beyond fluid delivery.
