Electrophysiology + TS Series

A consortium of researchers aimed to understand binocular encoding within the Damselfly Pre-motor Target Tracking Systems. Paloma Bellido of the University of Minnesota worked with Herzan to remove vibration noise from the electrophysiology testing setup created. Ultimately, the testing setup helped record intracellularly from neurons in damselflies.

Interesting Application Highlights*

The end result proved successful, including some highlights:

  • Demoiselles align their prey frontally during predatory flights
  • Target-selective descending neurons are homologous in dragonflies and damselflies
  • TSDN reference frame is binocular-fused in damselflies but sagittal in dragonflies
  • Summation to threshold explains binocular responses of demoiselle TSDNs
