This is a series of experiments investigating the tactile response of the protoplasmic tubes of Physarum polycephalum.
The experiments form the basis for the scientific paper published in the journal Materials Today together with Andrew Adamatzky: http://www.sciencedirect.com/science/article/pii/S136970211400025X
Abstrakt: We demonstrate how logical operations can be implemented in ensembles of protoplasmic tubes of acellular slime mold Physarum polycephalum. The tactile response of the protoplasmic tubes is used to actuate analogs of two- and four-input logical gates and memory devices. The slime mold tube logical gates display results of logical operations by blocking flow in mechanically stimulated tube fragments and redirecting the flow to output tube fragments. The slime mold based gates are non-electronic, simple and inexpensive, and several gates can be realized simultaneously at sites where protoplasmic tubes merge.
