Dopamine depletion causes fragmented clustering of neurons in the sensorimotor striatum: evidence of lasting reorganization of corticostriatal input.

Persistent cue-evoked activity of accumbens neurons after prolonged abstinence from self-administered cocaine.

Differences between accumbens core and shell neurons exhibiting phasic firing patterns related to drug-seeking behavior during a discriminative-stimulus task.

Changes in activity of the striatum during formation of a motor habit.

Dose- and rate-dependent effects of cocaine on striatal firing related to licking.

Evidence for habitual and goal-directed behavior following devaluation of cocaine: a multifaceted interpretation of relapse.

Decreased firing of striatal neurons related to licking during acquisition and overtraining of a licking task.

Acute effects of cocaine on movement-related firing of dorsolateral striatal neurons depend on predrug firing rate and dose.

Dose-dependent differences in short ultrasonic vocalizations emitted by rats during cocaine self-administration.

Evidence for learned skill during cocaine self-administration in rats.

Slow phasic and tonic activity of ventral pallidal neurons during cocaine self-administration.

Differential roles of ventral pallidum subregions during cocaine self-administration behaviors.

Effects of varying reinforcement probability on pavlovian approach behavior and ultrasonic vocalizations in rats.

Amphetamine's dose-dependent effects on dorsolateral striatum sensorimotor neuron firing.

Rat ultrasonic vocalizations demonstrate that the motivation to contextually reinstate cocaine-seeking behavior does not necessarily involve a hedonic response.
