Zusammenfassung:Eight mutants of Drosophila m. have been isolated that fail to display longlasting modification of "choice tube phototaxis". Two different classes of stocks defective in plasticity of phototaxis (dipp) can be discriminated: Mutants which are affected in the stability of the Prolonged Depolarising Afterpotential (PDA) in the peripheral retinula cell R1-R6. Mutants with normal PDA but abnormalities in fast escape phototaxis especially under conditions where only receptor cells R7-R8 serve as input for this behavioural trait.
