An Investigation of Quantum E ects in the Selectivity Filter of Ion Channel in a Brain Neuron Narges Moradi n moradi@ph iut ac ir 01 11 2015 Department of Physics Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Dr Vahid Salari vahidsalari@cc iut ac irAbstractRecently experimental evidences have strengthened the hypothesis that biological systemsmay use quantum e ects for their e cient functions Here we investigate ion channels in general and then focus on the small nanoscale partof ion channels in the excitable cells which is called selectivity lter First we discussabout the possibility of quantum e ects in the selectivity lter in ion channels that may haveimportant role s to explain di erent aspects of spike generation in excitable cells by usingHodgkin Huxley model with considering real structure of ion channels Here we examineparameters in a generalized model of HH to see that whether any parameter a ects the spikegeneration and then investigate di erent decoherence mechanisms regarding the quantumdynamics and energy transfer in these structures We will show that brain processes maybe derived from quantum e ects in nanostructures in neurons because of large decoherencetime Keywords Ion channel Selectivity lter Spike generation Hodgkin Huxley model Deco herence mechanism
