  • RE: Majorana fermions in brain qubits

    Majorana fermions could possibly contribute to qubit systems in mammalian brain,associated with astrocyte.
    Brain of mammals is richly endowed with astrocyte endfeet,which has more complex organisation linked to neurons in human brain,particularly.
    Astrocyte end feet have ultrastructures with an electron dense layer,EDL,so that they would conform to models of topological insulator,with a thin conducting layer,to be found in the electron dense membrane,in the end foot region close to the Extra Cellular Space,ECS,as a dielectric special medium in the cytoplasm environment.
    The interphase between the ECS and EDL,electron dense layer,of membraneous material in astrocytic end feet ultrastructure has proton channels.
    Some of the proton channels are found to exhibit proton tunneling effects based on deuterium currents.
    This can correspond to superconducting layer for proton currents,with proton pairing.
    Hence we have Josephson junction like EDL,ECS interfaces in brain which could account for quasiparticle like excitations, as Majorana fermions in brain,for implementing qubit systems.
