Roles for the Dorsal Striatum in Aversive Behavior

Frontiers in Cellular Neuroscience, 2021
The ability to identify and avoid environmental stimuli that signal danger is essential to survival. Our understanding of how the brain encodes aversive behaviors has been primarily focused on roles for the amygdala, hippocampus (HIPP), prefrontal cortex,

Striatal dopamine transmission is subtly modified in human A53Tα-synuclein overexpressing mice [PDF]

, 2012
Mutations in, or elevated dosage of, SNCA, the gene for α-synuclein (α-syn), cause familial Parkinson's disease (PD). Mouse lines overexpressing the mutant human A53Tα-syn may represent a model of early PD.

Modulation of Resting Connectivity Between the Mesial Frontal Cortex and Basal Ganglia

Frontiers in Neurology, 2019
Background: The mesial prefrontal cortex, cingulate cortex, and the ventral striatum are key nodes of the human mesial fronto-striatal circuit involved in decision-making and executive function and pathological disorders.

Altered fronto-striatal fiber topography and connectivity in obsessive-compulsive disorder. [PDF]

PLoS ONE, 2014
Fronto-striatal circuits are hypothesized to be involved in the pathophysiology of obsessive-compulsive disorder (OCD). Within this circuitry, ventral frontal regions project fibers to the ventral striatum (VS) and dorsal frontal regions to the dorsal ...

The organization of midbrain projections to the striatum in the primate: Sensorimotor-related striatum versus ventral striatum

Neuroscience, 1994
In order to examine the organization of nigrostriatal projections in the primate, the retrograde tracers Lucifer Yellow conjugated to dextran amines and horseradish peroxidase conjugated to wheatgerm agglutinin were injected into different regions of the dorsolateral and ventral striatum.

Reply: Differential functions of ventral and dorsal striatum [PDF]

Brain, 2015
Sir, In their letter concerning our recent report, Drs Zeighami and Moustafa discuss several previous studies investigating the functions of the ventral and dorsal striatum and the dissociation between action-value and stimulus-value learning. They note that in light of much of this previous work, our findings regarding Patient XG—who suffered ...

Maladaptive bias for extrahippocampal navigation strategies in aging humans. [PDF]

, 2013
Efficient spatial navigation requires not only accurate spatial knowledge but also the selection of appropriate strategies. Using a novel paradigm that allowed us to distinguish between beacon, associative cue, and place strategies, we investigated the ...

Preferential Reactivation of Motivationally Relevant Information in the Ventral Striatum [PDF]

Journal of Neuroscience, 2008
Spontaneous "off-line" reactivation of neuronal activity patterns may contribute to the consolidation of memory traces. The ventral striatum exhibits reactivation and has been implicated in the processing of motivational information. It is unknown, however, whether reactivating neuronal ensembles specifically recapitulate information relating to ...

Offline ventral subiculum-ventral striatum serial communication is required for spatial memory consolidation [PDF]

, 2019
The hippocampal formation is considered essential for spatial navigation. In particular, subicular projections have been suggested to carry spatial information from the hippocampus to the ventral striatum. However, possible cross-structural communication
