Transfer of learned behaviour. (a) Schematic of set-up for three slime moulds. (b) Photographs illustrate the fusion of two slime moulds. Close up of the point of contact between two slime moulds. Veins between the two slime moulds are apparent after 2 h. (c) Transfer of learned behaviour experiment where the merged entity resulted from the fusion of two habituated slime moulds (H) located at the periphery and one unhabituated slime mould (U) located at the centre of the merged entity. In this example, the pseudopod crossing the bridge comes from the unhabituated slime mould. (Online version in colour.)
