Stamos J, Ma S, Pawlak A, Engelhard N, Horvitz J, West M
Eur J Neurosci
. 2022 May;
56(1):3570-3590.
PMID: 35491443
The nucleus accumbens (NAc) core plays an important role in processing of events related to food reward, such as conditioned cues, approach or consumption. Nonetheless, there is lack of clarity...

Vega-Villar M, Horvitz J, Nicola S
Nat Commun
. 2019 Sep;
10(1):4429.
PMID: 31562332
Learning associations between environmental cues and rewards is a fundamental adaptive function. Via such learning, reward-predictive cues come to activate approach to locations where reward is available. The nucleus accumbens...

Dobrovitsky V, West M, Horvitz J
Eur J Neurosci
. 2019 Jul;
50(9):3403-3415.
PMID: 31340074
Nucleus accumbens dopamine plays a key role in reward-directed approach. Past findings suggest that dopamine's role in the expression of learned behavior diminishes with extended training. However, little is known...

Crossley M, Horvitz J, Balsam P, Ashby F
J Neurophysiol
. 2015 Oct;
115(1):240-54.
PMID: 26467514
The basal ganglia are a collection of subcortical nuclei thought to underlie a wide variety of vertebrate behavior. Although a great deal is known about the functional and physiological properties...

Coffey K, Barker D, Ma S, Root D, Martinez L, Horvitz J, et al.
Behav Brain Res
. 2012 Oct;
237:256-62.
PMID: 23022752
Long Evans rats (n=32) were trained for 2 weeks to respond to an auditory conditioned stimulus (CS) which signaled the delivery of a 20% sucrose unconditioned stimulus (US) with varying...

Choi W, Campbell C, Balsam P, Horvitz J
Behav Neurosci
. 2011 Sep;
125(5):705-13.
PMID: 21942433
Various lines of evidence suggest that disruptions in brain dopamine (DA) transmission produce behavioral impairments that can be overcome by salient response-eliciting environmental stimuli. We examined here whether D1 receptor...

Ashby F, Turner B, Horvitz J
Trends Cogn Sci
. 2010 Mar;
14(5):208-15.
PMID: 20207189
In the 20th century it was thought that novel behaviors are mediated primarily in cortex and that the development of automaticity is a process of transferring control to subcortical structures....

Choi W, Morvan C, Balsam P, Horvitz J
Behav Neurosci
. 2009 Dec;
123(6):1279-87.
PMID: 20001111
Experimentally induced and parkinsonian disruptions in dopamine (DA) transmission are associated with motor abnormalities that include a reduced likelihood of behavioral response initiation and an increased duration of executed responses....

Horvitz J
Behav Brain Res
. 2009 Jan;
199(1):129-40.
PMID: 19135093
While midbrain DA neurons show phasic activations in response to both reward-predicting and salient non-reward events, activation responses to primary and conditioned rewards are sustained for several hundreds of milliseconds...

Wickens J, Horvitz J, Costa R, Killcross S
J Neurosci
. 2007 Aug;
27(31):8181-3.
PMID: 17670964
Recent studies suggest new ways to interpret dopaminergic actions in goal-directed performance and habitual responding. In the early stages of learning dopamine plays an essential role, but with extended training...
