The ventrolateral striatum is found to be recruited during the encoding of cocaine preference, within which Egr2-expressing ensembles are functionally important, as is the expression of Egr2 within them.
Optical recordings reveal previously unknown neuromodulator dynamics in the striatum during animal movements that suggest a new interpretation of the underpinnings of bradykinetic movements exhibited in Parkinson's Disease patients.
Dorsomedial and dorsolateral striatal neural activity differ during early learning of action sequences but do not change with performance improvement across sessions, and become similar after extended training.
The numerous reports in support of action-value representation in the striatum are based on statistical analyses that are subject to two critical confounds and, thus, this long-held belief of striatal action-value representation should be retested using different experiments and analyses.
Analysis of slow wave brain state unravels the functional connectivity and the biological substrate of the rodent dorsolateral and dorsomedial striatum, demonstrating its organization in two non-overlapping circuits.
Dopamine signals in the ventral, dorsomedial, and dorsolateral striatum are modulated by various variables, such as stimulus-associated value, choice, confidence, but these modulations can be inclusively explained by TD errors.
The first comprehensive map of all excitatory inputs to the mouse striatum is presented and used to define and demarcate striatal subdivisions, including a previous unappreciated novel subdivision in the posterior striatum.
