  • Title: [Recording of synaptic currents with extracellular electrodes].
    Author: Chizhov AV, Pokrovskiĭ AN, Terry J, Sargsian A.
    Journal: Biofizika; 2009; 54(3):495-9. PubMed ID: 19569512.
    Abstract:
    Recordings made by multielectrodes distributed in depth of the cortex are used for the system level study of the brain. The distribution of the extracellular potential obtained contains information about the input signals of pyramidal neurons in the cortex, the synaptic currents. A method of the estimation of the synaptic current distribution is described, which is based on the solution of the reverse problem for a system of homogeneously distributed parallel cylinders as a model of dendrites of the pyramidal neurons. The estimations are compared to the data both known from literature and obtained by an independent model.
