Puberty Triggers Brain Rewiring in Genetic Condition Tied to Autism

UTSW researchers used a technique called optogenetic circuit mapping in which they inserted a gene into targeted neurons, allowing their activity to be controlled by light. By stimulating neurons that deliver inputs to the HVC, an area of the avian brain involved in birdsongs, then measuring the electrical activity of outputting neurons, the team could see which neurons communicated with one another.

Researchers at WashU Medicine identified a direct connection between cancer-related inflammation and the loss of motivation characteristic of advanced cancer. In a mouse study they describe a brain pathway that starts with neurons (labeled in green, above) that sense inflammation signals, and the researchers were able to treat the loss of motivation by blocking this pathway.

Nk3R antagonism decreases fear memory consolidation. (A) Experimental procedure of fear memory consolidation after stress. Created with Biorender. (B) Fear acquisition and expression in mice administered with Osanetant. (C) Effect in the fear memory consolidation after administration of Osanetant (5 mg/kg, ip) or Vehicle 30 min after stress (IMO) in adult females (n = 12 per group) (p = 0.038, η2 = 0.798). Analyzed by Generalized Linear Model with least significant difference (LSD) correction.
