Anticipation of appetitive operant action induces sustained dopamine release in the nucleus accumbens

This study compares Pavlovian and operant conditioning in rats to show that operant action anticipation induces sustained dopamine release in the nucleus accumbens, distinct from reward prediction error signals.

Nucleus-accumbens dopamine tracks aversive-stimulus duration and prediction but not value or prediction error

A novel automated approach for improving standardization of the marble burying test enables quantification of burying bouts and activity characteristics

This paper introduces an automated method to quantify burying bouts and activity characteristics in the marble burying test using machine learning, revealing differences in behavior across mouse models of neurodevelopmental disorders.
