[Pavan Ramdya @ramdya]

This is a really heroic experiment recording associative learning neurons in the fly brain over two hours while two flies interact with one another. This device and this approach can generally enable many more kinds of social interaction experiments

[Victor Lobato Rios @VLobatoRios]

We recorded the activity of neurons within this network during 2 hours of social interactions. Interestingly, as the animals became more sociable the baseline and locomotor-related activity greatly diminished in MBONs previously implicated in aversive learning.

[Pavan Ramdya @ramdya]

I found @VLobatoRios's experiment with a fly and a beetle really clever. It tests whether, when flies becoming sociable towards one another, it is due to a general reduction in behavioral excitability or if it is specific to conspecific (same-species) interactions.

[Victor Lobato Rios @VLobatoRios]

However, single-housed animals can learn to be sociable after spending several hours with other flies, or more specifically, smelling other flies. Importantly, this shift in behavior seems to be tuned to conspecifics since flies never stop evading beetles, for example.

[Pavan Ramdya @ramdya]

When @VLobatoRios first showed me videos like the one the left, with one female fly running way from the other female fly, I was stunned

[Victor Lobato Rios @VLobatoRios]

We found that if we isolate flies before they eclose, and keep them living alone, they’ll display a constellation of fearful reactions the first time they encounter other flies. Contrary to the sociable behaviors shown by flies housed in a group.

[Pavan Ramdya @ramdya]

Watching these animals touch one another reveals just how rich inter-fly social interactions are... @VLobatoRios designed a novel two-photon microscopy recording system that allows us to record one fly's brain while it interacts with another fly

[Victor Lobato Rios @VLobatoRios]

I'm thrilled to share this story! Flies tend to aggregate, as I’m sure you have experienced in your kitchen. They lay eggs around the same places and form clusters even in the absence of food. But, what happens when they meet other flies for the first time? ...

[Pavan Ramdya @ramdya]

@EPFL_en @Brainmind_EPFL @epflSV @EPFL_BioE

[Pavan Ramdya @ramdya]

Being raised alone makes flies afraid of one another!
But exposure to other flies makes them become sociable. @VLobatoRios found and recorded specific learning circuits in the brain that regulate this transition. Read more in our new preprint:
