Concurrent activation of striatal direct and indirect pathways during action initiation

…, X Jin, MD Pham, SS Vogel, DM Lovinger, RM Costa - Nature, 2013 - nature.com
The basal ganglia are subcortical nuclei that control voluntary actions, and they are affected
by a number of debilitating neurological disorders 1 , 2 , 3 , 4 . The prevailing model of basal …

Chronic stress causes frontostriatal reorganization and affects decision-making

…, P Morgado, AR Mesquita, JJ Cerqueira, RM Costa… - Science, 2009 - science.org
The ability to shift between different behavioral strategies is necessary for appropriate
decision-making. Here, we show that chronic stress biases decision-making strategies, affecting …

Dynamic reorganization of striatal circuits during the acquisition and consolidation of a skill

…, MI Davis, AC Hansson, DM Lovinger, RM Costa - Nature …, 2009 - nature.com
The learning of new skills is characterized by an initial phase of rapid improvement in
performance and a phase of more gradual improvements as skills are automatized and …

Mechanism for the learning deficits in a mouse model of neurofibromatosis type 1

RM Costa, NB Federov, JH Kogan, GG Murphy, J Stern… - nature, 2002 - nature.com
Neurofibromatosis type I (NF1) is one of the most common single-gene disorders that causes
learning deficits in humans 1 . Mice carrying a heterozygous null mutation of the Nf1 gene (…

Start/stop signals emerge in nigrostriatal circuits during sequence learning

X Jin, RM Costa - Nature, 2010 - nature.com
Learning new action sequences subserves a plethora of different abilities such as escaping
a predator, playing the piano, or producing fluent speech. Proper initiation and termination of …

[HTML][HTML] Orbitofrontal and striatal circuits dynamically encode the shift between goal-directed and habitual actions

CM Gremel, RM Costa - Nature communications, 2013 - nature.com
Shifting between goal-directed and habitual actions allows for efficient and flexible decision
making. Here we demonstrate a novel, within-subject instrumental lever-pressing paradigm, …

Basal ganglia subcircuits distinctively encode the parsing and concatenation of action sequences

X Jin, F Tecuapetla, RM Costa - Nature neuroscience, 2014 - nature.com
Chunking allows the brain to efficiently organize memories and actions. Although basal
ganglia circuits have been implicated in action chunking, little is known about how individual …

Matrix metalloproteinase-9 is required for hippocampal late-phase long-term potentiation and memory

…, P Okulski, J Dzwonek, RM Costa… - Journal of …, 2006 - Soc Neuroscience
Matrix metalloproteinases (MMPs) are extracellular proteases that have well recognized roles
in cell signaling and remodeling in many tissues. In the brain, their activation and function …

Dopamine neuron activity before action initiation gates and invigorates future movements

JA Da Silva, F Tecuapetla, V Paixão, RM Costa - Nature, 2018 - nature.com
Deciding when and whether to move is critical for survival. Loss of dopamine neurons (DANs)
of the substantia nigra pars compacta (SNc) in patients with Parkinson’s disease causes …

[HTML][HTML] Neurofibromin regulation of ERK signaling modulates GABA release and learning

Y Cui, RM Costa, GG Murphy, Y Elgersma, Y Zhu… - Cell, 2008 - cell.com
We uncovered a role for ERK signaling in GABA release, long-term potentiation (LTP), and
learning, and show that disruption of this mechanism accounts for the learning deficits in a …
