Time-varying excitatory and inhibitory synaptic inputs govern activity of neurons and process information in the brain. The importance of trial-to-trial fluctuations of synaptic inputs has recently been investigated in neuroscience. Such fluctuations are ignored in the most conventional techniques because they are removed when trials are averaged during(More)
Neuron transforms information via a complex interaction between its previous states, its intrinsic properties, and the synaptic input it receives from other neurons. Inferring synaptic input of a neuron only from its membrane potential (output) that contains both sub-threshold and action potentials can effectively elucidate the information processing(More)

complies with the regulations of the University and meets the accepted standards with respect to originality and quality. The discrete wavelet transform (DWT) has been widely used in many fields, such as image compression, speech analysis and pattern recognition, because of its capability of decomposing a signal at multiple resolution levels. Due to the(More)
