Retrosplenial cortical reorganization during late adolescence introduces instability of contextual memory circuits

Hui Zhang, Zorica Petrovic, Elizabeth M. Wood, Ana Cicvaric et autres

Hippocampal and cortical memory circuits, which enable the capacity to remember details from one's past, are believed to reach maturity by early adolescence. Here, we demonstrate that the transition from early to late adolescence involves extensive reorganization of the retrosplenial (RSP) cortex …

Median Raphe projection into the dorsal dentate gyrus modulates anxiety behavior and coping with learning under stress

J. Quan, M. Kriebel, R. Anunu, M. Snippe-Strauss et autres

The Median Raphe (MR) provides a major, mainly serotonergic, input to the hippocampus, particularly influencing the dentate gyrus (DG), but its specific role remains unclear. Here, focusing on the dorsal DG, we investigated its contribution to anxiety-like behavior and learning under stress, …

Effects of TrkB-related induced metaplasticity within the BLA on anxiety, extinction learning, and plasticity in BLA-modulated brain regions

Joyeeta Dutta Hazra, Kuldeep Shrivastava, Lisa-Sophie Wüstner, Rachel Anunu et autres

BACKGROUND: Neuronal plasticity within the basolateral amygdala (BLA) is fundamental for fear learning. Metaplasticity, the regulation of plasticity states, has emerged as a key mechanism mediating the subsequent impact of emotional and stressful experiences. After mRNA knockdown of synaptic plasticity-related TrkB, we …

Behavioural profiling following acute stress uncovers associations with future stress sensitivity and past childhood abuse

Sharona L. Rab, Lisa M. Simon, Rani Amit Bar-On, Gal Richter‐Levin et autres

Background: Individuals greatly differ in their responses to acute stress, ranging from resilience to vulnerability that may yield stress-related psychopathology. Stress-related psychopathologies involve, by definition, substantial modifications across multiple behavioural domains, including impaired cognitive, affective and social functioning. Nevertheless, and despite extensive …

Intra-BLA alteration of interneurons’ modulation of activity in rats, reveals a dissociation between effects on anxiety symptoms and extinction learning

Rinki Saha, Lisa-Sophie Wüstner, Darpan Chakraborty, Rachel Anunu et autres

The basolateral amygdala (BLA) is a dynamic brain region involved in emotional experiences and subject to long-term plasticity. The BLA also modulates activity, plasticity, and related behaviors associated with other brain regions, including the mPFC and hippocampus. Accordingly, intra-BLA plasticity can be …

Selective knockdown of GABAA‐α2 subunit in the dorsal dentate gyrus in adulthood induces anxiety, learning and memory deficits and impairs synaptic plasticity

Kuldeep Kumar Tripathi, Somoday Hazra, Joyeeta Dutta Hazra, Silvia A. Mandel et autres

Animal studies and clinical trials suggest that maintenance of gamma-aminobutyric acid (GABA)-ergic activity may be crucial in coping with stressful conditions, anxiety and mood disorders. Drugs highly efficient in promoting anxiolysis were shown to activate this system, particularly via the α2-subunit of …

Distinct Neural Representations and Cognitive Behaviors Attributable to Naturally Developed Active Avoidance or Reactive Escape Strategies in the Male Rat

Liang Jing, Chen Ma, Lin Xu, Gal Richter‐Levin

BACKGROUND: The high individual variability in coping with stress is often attributed to genetic background differences, sustained environmental conditions, or a combination of both. However, the neural mechanisms underlying coping style variability are still poorly understood. METHODS: Here we examined the impact …
