How fruit flies see love: An AI model of the male’s visual neurons during courtship

Written by Payel Chatterjee for the Princeton Neuroscience Institute

For fruit flies, love is not blind. During courtship, a male fruit fly relies on his sense of vision to pursue a female fruit fly—if she is far away, he will speed up; if she is to the left, he will turn left; if she is close, he will serenade her with a complex acoustic signal generated by vibrating his wings. But how does the visual…

Written by Alaina O'Regan, Office of the Dean for Research

A new study shows that social isolation changes the behavior and brain development of bumblebees, but not in the way researchers expected.

The study explored how bumblebees, which depend largely on their social instincts for survival, were impacted by being socially isolated during a key developmental period.

The researchers…

Author
Written by Sharon Waters for the Office of Engineering Communications

Gabbie Acot started off on a pre-med track at Princeton before broadening her studies to include structural engineering and then neuroscience. Her senior thesis project brought together all of these interests, combining video analysis, neuroimaging and numerical modeling to perform a forensic reconstruction of college football head impacts.
