MBON screen progress 18.05.2026

PI- values for world learning torque experiments. As usual the flies were tethered and subjected to adverse stimuli by laser dependent on torque domain, which also controlled arena color. Flies that show positive PI at the end indicate premature habit formation as WT flies don’t learn under these conditions in this time frame.

Same as above except the pretest preference has been subtraced

Current p-values for all the tested groups. Should be 25-30 flies at trial end.

Trans-tango repeat from previous week

on Monday, May 18th, 2026 12:21 | by Ipek Subay

I was not able get any trans-tango signal from my reciprocal MB399B crosses so I repeated the experiment with anti-RFP antibody instead of anti-HA antibody

77124xMB399B (MBON02 reciprocal cross) stained with rabbit anti-GFP (2nd: anti-rabbit 488), rat anti-RFP (2nd: anti-rat 555), nc82 (2nd: anti-mouse 650)

MBON screen progress 11.05.2026

on Monday, May 11th, 2026 12:25 | by Fridrik Kjartansson

PI-values unsubtracted:

Results from premature habit formation torque measurements of four drosophila crosses: MB399B, MB050B & MB027B gal4 driver lines crossed with UAS-Tetanus toxin lines and Wild type Berlin crossed with UAS-TnT as control. Which line is which is still unknown as the screen is incomplete and researcher must remain blind. It appears two crosses strongly form habits prematurely, one doesn’t and one is still on the borderline.

PI-values subtracted:

Same results as above except with pretest bias subtracted.

p-values:

p-values for the different groups
