Light-sensitive cells needed to keep long-term memory in fruit flies

AI simplified

Abstract

Circadian photoreceptors are essential for maintaining long-term memory in fruit flies.

  • Light is necessary for long-term memory maintenance in Drosophila melanogaster.
  • The Pigment dispersing factor (Pdf) is crucial for the light-dependent maintenance of courtship long-term memory.
  • Pdf neurons can directly sense light through circadian photoreceptors Rhodopsin 7 (Rh7) and Cryptochrome (Cry).
  • Circadian photoreceptors in Pdf neurons are required for the maintenance of courtship long-term memory.
