Fungi anaesthesia

  title={Fungi anaesthesia},
  author={A. Adamatzky and Antoni Gandia},
Electrical activity of fungus Pleurotus ostreatus is characterised by slow (hours) irregular waves of baseline potential drift and fast (minutes) action potential likes spikes of the electrical potential. An exposure of the mycelium colonised substrate to a chloroform vapour lead to several fold decrease of the baseline potential waves and increase of their duration. The chloroform vapour also causes either complete cessation of spiking activity or substantial reduction of the spiking frequency… Expand


On spiking behaviour of oyster fungi Pleurotus djamor
It is demonstrated that the fungi generate action potential like impulses of electrical potential, and it is shown that non-stimulated fruit bodies of a cluster react to the thermal stimulation, with a single action-potential like spike, faster than the stimulated fruit body does. Expand
"Action potentials" in Neurospora crassa, a mycelial fungus.
Identification of action potential-like disturbances in fungi means that such behavior has now been found in all major biologic taxa which have been probed with suitable electrodes. Expand
Studies on microplasmodia of Physarum polycephalum V: electrical activity of different types of microplasmodia and macroplasmodia.
The investigation favours the hypothesis that ion fluxes across the cell membrane and perhaps between intracellular compartments may act as a trigger mechanism for a still unknown oscillator-system which controls cell movement phenomena in the acellular slime molds. Expand
It is clear that electrophysiology is an important aspect of many plant movements, and bears a remarkable similarity to excitation in animal nervous systems. Expand
Bioelectric phenomena in the myxomycete plasmodium and their relation to protoplasmic flow
Abstract 1. 1. Potential differences between the two loci of the slime mold ( Physarum polycephalum ) connected with a single strand of protoplasm were determined successively and the mode of theirExpand
The effect of inhalational anaesthetics on the swimming velocity of Tetrahymena pyriformis.
The effect of 6 inhalational anaesthetics on speed of swimming (produced by ciliary movement) has been studied in Tetrahymena pyriformis. There was no evidence of stimulation at low dose levels andExpand
Control of phloem unloading by action potentials in Mimosa
In the sensitive plant, Mimosa pudica, action potentials arise when the leaves are touched and they trigger a sudden decrease in turgor of the pulvinar motor cells, which causes the leaf to close, and it is suggested that it also triggers phloem unloading of sucrose in the pulvini. Expand
Mimosa pudica: Electrical and mechanical stimulation of plant movements.
The hydroelastic curvature mechanism closely describes the kinetics of M. pudica leaf movements and is related to stimulus perception, electrical signal transmission and induction of mechanical, hydrodynamical and biochemical responses. Expand

Rapid bendings of the pulvinus inMimosa pudica, of the trap lobes inDionaea muscipula andAldrovanda vesiculosa, and of the tentacle in Drosera are triggered by action potentials in their motor cells.Expand
Action of Narcotics on the Ameba by Means of Microinjection and Immersion.
Comparative studies were made on the influence of the narcotics: ethyl alcohol, chloretone, ether, and chloroform on the protoplasm of Amoeba dubia, with special reference to their action on theExpand
