A new study reveals that mice instinctively display rescue-like behaviors toward anesthetized peers, offering powerful evidence that prosociality may be hardwired in mammals.

Techniques such as optogenetics, chemogenetics, and fiber photometry are used to monitor and manipulate cell types within the mouse brain while the animal engages in motivated behaviors. The objective ...

Using a technique called fiber photometry, light can be used to trigger and then measure fluorescence fluctuations from a biosensor like GRAB, whenever serotonin is detected. The team was able to ...

and fiber photometry. They discovered that oxytocin (OXT) neurons in the paraventricular nucleus of the hypothalamus are activated when the observer mouse detects distress signals from a peer.

Cohorts underwent short training sessions in which lever presses earned food pellets. Fiber photometry recorded neuronal ...

In response, the observer mouse engaged in allogrooming and allolicking ... optogenetics, and fiber photometry. Specifically, the pathway through the central amygdala is responsible for decoding ...
