In the present article, the principle of the peak-scaled fluctuation analysis is described in the context of synaptic transmission between neurons. Furthermore, this fluctuation analysis is applied to glutamate receptor channnel in order to investigate the properties of AMPA receptor channels which underlay long-term change in synaptic strength, which is thought to be substrate of memory and learning in the brain, observed in cerebellar Purkinje cell. Whole cell patch clamp technique was used to measure the synaptic currents from Purkinje cell by parallel fiber activation. The decay phases of the postsynaptic currents were approximated by a single exponential function. The mean current and variance relationship was fitted with the parabolic curves to estimate the single channel conductance. It was suggested that no change in single channel conductance was observed before and during LTD.}, pages = {51--74}, title = {NON-STATIONARY NOISE ANALYSIS AND SYNAPTIC TRANSMISSION}, volume = {2013}, year = {2013} }
