Spatial mapping reveals multi-step pattern of wound healing in Physarum polycephalum
Wounding is a severe impairment of function, especially for an exposed organism like the network-forming true slime mould Physarum polycephalum. The tubular network making up the organism’s body plan is entirely interconnected and shares a common cytoplasm. Oscillatory contractions of the enclosing tube walls drive the shuttle streaming of the cytoplasm. Cytoplasmic flows underlie the reorganiz...
متن کاملLogical 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...
متن کاملPhysarum 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...
متن کاملOn electrical correlates of Physarum polycephalum spatial activity: Can we see Physarum Machine in the dark?
Plasmodium of Physarum polycephalum is a single cell visible by unaided eye, which spans sources of nutrients with its protoplasmic network. In a very simple experimental setup we recorded electric potential of the propagating plasmodium. We discovered a complex interplay of short range oscillatory behaviour combined with long range, low frequency oscillations which serve to communicate informa...
متن کاملPhysarum 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...
