to threat and may be disrupted in anxiety and post-trauma psychopathology. Here we review …

Medial prefrontal cortex encoding of stress and anxiety

DS Jacobs, B Moghaddam - International review of neurobiology, 2021 - Elsevier
The prefrontal cortex (PFC) is involved in adaptive control of behavior and optimizing action
selection. When an organism is experiencing an aversive event, such as a sustained state of …

Stress-driven potentiation of lateral hypothalamic synapses onto ventral tegmental area dopamine neurons causes increased consumption of palatable food

LE Linders, L Patrikiou, M Soiza-Reilly… - Nature …, 2022 - nature.com

How stress influences the dynamic plasticity of the brain's extracellular matrix

BJ Laham, E Gould - Frontiers in Cellular Neuroscience, 2022 - frontiersin.org
Diffuse and structured extracellular matrix (ECM) comprise∼ 20% of the brain's volume and
play important roles in development and adult plasticity. Perineuronal nets (PNNs) …

Medial prefrontal cortical control of reward‐and aversion‐based behavioral output: Bottom‐up modulation

V Pastor, JH Medina - European Journal of Neuroscience, 2021 - Wiley Online Library
How does the brain guide our actions? This is a complex issue, where the medial prefrontal
cortex (mPFC) plays a crucial role. The mPFC is essential for cognitive flexibility and …

Paraventricular thalamus dynamically modulates aversive memory via tuning prefrontal inhibitory circuitry

T Wang, R Yan, X Zhang, Z Wang, H Duan… - Journal of …, 2023 - Soc Neuroscience
The impact of stress on the formation and expression of memory is well studied, especially
on the contributions of stress hormones. But how stress affects brain circuitry dynamically to …

[HTML][HTML] Longitudinal monitoring of prefrontal cortical ensemble dynamics reveals new insights into stress habituation

S Patel, K Johnson, D Adank, LE Rosas-Vidal - Neurobiology of stress, 2022 - Elsevier
The prefrontal cortex is highly susceptible to the detrimental effects of stress and has been
implicated in the pathogenesis of stress-related psychiatric disorders. It is not well …

Inducible Nitric Oxide Synthase Inhibition in the Medial Prefrontal Cortex Attenuates the Anxiogenic-Like Effect of Acute Restraint Stress via CB1 Receptors

AA Coelho, C Vila-Verde, AG Sartim, DL Uliana… - Frontiers in …, 2022 - frontiersin.org

Dopaminergic and noradrenergic modulation of stress-induced alterations in brain activation associated with goal-directed behaviour

P van Ruitenbeek, CWEM Quaedflieg… - Journal of …, 2021 - journals.sagepub.com
Background: Acute stress is thought to reduce goal-directed behaviour, an effect purportedly
associated with stress-induced release of catecholamines. In contrast, experimentally …

Learning of probabilistic punishment as a model of anxiety produces changes in action but not punisher encoding in the dmPFC and VTA

DS Jacobs, MC Allen, J Park, B Moghaddam - Elife, 2022 - elifesciences.org
