Common time-frequency analysis of local field potential and pyramidal cell activity in seizure-like events of the rat hippocampus.

abstract：OBJECTIVE:The various parameters that define a hand movement such as its trajectory, speed, etc, are encoded in distinct brain activities. Decoding this information from neurophysiological recordings is a less explored area of brain-computer interface (BCI) research. Applying non-invasive recordings such as electroence...
