Control of chemotaxis in Physarum polycephalum.

Control of chemotaxis in Physarum polycephalum

Plasmodia migrate towards those situations which increase the frequency of their alternations in streaming, and away from those which decrease the frequency. Therefore peristalsis-like waves in Physarum move in the direction opposite from the net movement of the organism. The mechanism is fundamentally related to other known types of chemotaxis.

Logical Modelling of Physarum Polycephalum

In the paper we proposed a novel model of unconventional computing where a structural part of computation is presented by dynamics of Plasmodium of Physarum polycephalum, a large single cell. We sketch a new logical approach combining conventional logic with process calculus to demonstrate how to employ formal methods in design of unconventional computing media presented by Physarum polycephalu...

Physarum polycephalum Histones

Physarumpolycephalum is an acellular slime mould whose histones are of general interest because they allow comparisons to be made between lower eukaryote and higher eukaryote histones and, perhaps more importantly, they provide a unique opportunity for the study of histone changes in the mitotic cycle, which is naturally synchronous in P. polycephalum plasmodia, and during differentiation. Stud...

Physarum Polycephalum changes polyaniline properties

Physarum polycephalum slime mould can modify polyaniline (PANI) features due to its internal activity. We created networks with different conductivity made by the slime mould on PANI substrates. Thus, Physarum’s growth results in changing the conductivity state of PANI layers, providing negative and positive patterning of the samples. A spectrophotometric scanner is here exploited to investigat...
