Torque Measurements 24-27.2.2026

on Monday, March 2nd, 2026 4:39 | by Fridrik Kjartansson

Results from tethered flight in torque meter. Fly fixed to hook and flight torque measured while laser punishes either left or right turning. Higher PI score indicates longer stay in unpunished domain, orange colored periods are punished. Higher scores in period 9, 12 and 13 indicates learning. Fly genotype is Wild type Berlin, N=16.

Same as above, with PI adjusted to factor in initial domain preference.

A low P-score indicates that the result is statistically significant and the flies indeed learned.

Pie charts indicate efficiency of experiment success. Blue wedge represents flies that completed trial, other colors represent flies that failed. Efficiency still low, using laser at 100% duty cycle often causes flies to stop flying unless directed at exactly the right position on their antennae.

Torque measurements 12.02.2026

Torque results 12.02.2026, learning is abolished and many of the flies died. Think improper feeding is to blame. Granulated sugar had become encrusted and possibly inaccessible to the flies, potentially resulting in starvation. In the future, I’ll resolve to use less sugar and to clean more frequently to prevent this kind of buildup.

Torque measurements 10.02.2026

on Friday, February 13th, 2026 12:31 | by Fridrik Kjartansson

Results for 10.02.2026, 24 flies, 7 completed trial. Main source of failure was flies stopping flight and refusing to resume. Had some difficulty getting flightless torque on the unpunished domain.
