Neural structures mediating expression and extinction of platform-mediated avoidance

C Bravo-Rivera, C Roman-Ortiz… - Journal of …, 2014 - Soc Neuroscience
Individuals use both passive and active defensive responses to environmental threats. Much
is known about the neural circuits of passive defensive responses (eg, freezing), but less is …

Infralimbic D2 receptors are necessary for fear extinction and extinction-related tone responses

D Mueller, C Bravo-Rivera, GJ Quirk - Biological psychiatry, 2010 - Elsevier
BACKGROUND:: Fear extinction is dependent on plasticity in the infralimbic prefrontal cortex,
an area heavily innervated by midbrain dopaminergic inputs. Dopamine D2 receptors are …

[PDF][PDF] Opposing contributions of GABAergic and glutamatergic ventral pallidal neurons to motivational behaviors

M Stephenson-Jones, C Bravo-Rivera, S Ahrens… - Neuron, 2020 - cell.com
The ventral pallidum (VP) is critical for invigorating reward seeking and is also involved in
punishment avoidance, but how it contributes to such opposing behavioral actions remains …

[HTML][HTML] Persistent active avoidance correlates with activity in prelimbic cortex and ventral striatum

C Bravo-Rivera, C Roman-Ortiz… - Frontiers in behavioral …, 2015 - frontiersin.org
Persistent avoidance is a prominent symptom of anxiety disorders and is often resistant to
extinction-based therapies. Little is known about the circuitry mediating persistent avoidance. …

Active avoidance requires inhibitory signaling in the rodent prelimbic prefrontal cortex

MM Diehl, C Bravo-Rivera, J Rodriguez-Romaguera… - Elife, 2018 - elifesciences.org
10.7554/eLife.34657.001 Much is known about the neural circuits of conditioned fear and its
relevance to understanding anxiety disorders, but less is known about other anxiety-related …

The study of active avoidance: A platform for discussion

MM Diehl, C Bravo-Rivera, GJ Quirk - Neuroscience & Biobehavioral …, 2019 - Elsevier
Traditional active avoidance tasks have advanced the field of aversive learning and memory
for decades and are useful for studying simple avoidance responses in isolation; however, …

Prefrontal circuits signaling active avoidance retrieval and extinction

FJ Martínez-Rivera, C Bravo-Rivera… - …, 2019 - Springer
Objective Neurons in PL and IL project densely to two areas implicated in active avoidance:
the basolateral amygdala (BLA) and the ventral striatum (VS). We therefore combined c-Fos …

[HTML][HTML] Stress, associative learning, and decision-making

J Giovanniello, C Bravo-Rivera, A Rosenkranz… - Neurobiology of learning …, 2023 - Elsevier
Exposure to acute and chronic stress has significant effects on the basic mechanisms of
associative learning and memory. Stress can both impair and enhance associative learning …

Fear signaling in the prelimbic-amygdala circuit: a computational modeling and recording study

S Pendyam, C Bravo-Rivera… - Journal of …, 2013 - journals.physiology.org
The acquisition and expression of conditioned fear depends on prefrontal-amygdala circuits.
Auditory fear conditioning increases the tone responses of lateral amygdala neurons, but …

[HTML][HTML] The effect of repeated exposure to ethanol on pre-existing fear memories in rats

…, MY Hernández-Rodríguez, C Bravo-Rivera… - …, 2015 - Springer
Rationale There is a high degree of comorbidity between alcohol use disorder and post-traumatic
stress disorder (PTSD), but little is known about the interactions of ethanol with …
