Life & Non-humans

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.

MIT engineers engineered bacteria to produce hyperspectral signals that can be detected as far as 90 meters away. Their work could lead to the development of bacterial sensors for agricultural to monitor crop health, for example. Credits:Image: Jose-Luis Olivares, MIT; iStock

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.
