Researchers discovered that anxious individuals utilize a less optimal region of the forebrain when navigating socially challenging situations compared to their non-anxious counterparts. This was determined through brain scans that mapped regions active during simulated social scenarios.

… During the terminal phase, the cognitive developmental age of JNCL patients is below 2 years. At this stage of mental development individuals act primarily from a concrete world of consciousness and do not have the cognitive ability to encounter a normal anxiety response. Instead, they experience the evolutionary basic emotion of fear, and as
Fluoxetine (Prozac), a common antidepressant, was found to enhance the erasure of learned fear responses and facilitate spatial pattern learning in mice. The study also found the TrkB receptor in PV+ interneurons plays a crucial role in these effects, which may offer new possibilities for the development of psychiatric treatments targeting brain plasticity.
Although the specific role of the uncinate fasciculus (UF) in emotional processing in patients with obsessive–compulsive disorder (OCD) has been investigated, the exact focal abnormalities in the UF have not been identified. The aim of the current study was to identify focal abnormalities in the white matter (WM) microstructure of the UF and to determine
Biological Psychiatry, Volume 93, Issue 8, 2023 Apr 15, Pages 739-750 | Goldway, Noam; Eldar, Eran; Shoval, Gal;…AbstractA central goal of computational psychiatry is to identify systematic relationships between transdiagnostic dimensions of psychiatric symptomatology and the latent learning and decision-making computations that inform individuals’ thoughts,…
Dogs with anxiety have stronger neural connections between the amygdala and other areas of the anxiety network in the brain compared to less anxious dogs.
