Some speculate that the tribes of the Americas colonialists encountered so many hundreds of years ago were actually not “technologically behind” - a racist belief still in operation in some quarters, but that in fact in possession of knowledge many years in advance of occidental culture which we are only now catching up with :
Casual Comparison epidermis of tobacco cells and Shapibo art :
Extremely fast action potential recorded today in a plant in response to burning a leaf - sorry vegetable world ! Also learnt how to make agar electrodes, the agar forms a jelly which mixed with high concentration salt solution is conductive - will test these tomorrow
So action potentials may propogate more slowly in some plants - but there is probably evolutionary pressure for fast action potentials such as the ones found in the venus fly trap and others that have not been discovered yet. It is the opinion of the electrophysiologists at LINV that action potentials found in plants of 270m/s are anything but instrumention error however.
It is time to invest in a cheap usb dtat aquisition board and instrumentation amplifier - but which one ? I need to get the signal from the board to max msp . Plant > instrumentation amplifier > data aquisition board (DAQ) > MaxMSP
So if action potentials in animals and nerves are discreet values , like on off , or morse code, with stable voltages, whereas plant action potentials vary more in values what does this imply ? Are subtler ion fluxes in plants more important that such largescale voltage peaks as action potentials ?
