采用局部场电位小波包熵分析空间频率特性
Analyzing spatial frequency characteristic by using wavelet packet entropy of local field poten-tial
摘要
Abstract
Spatial frequency is one of the basic properties in visual stimuli, to study the response of neurons in visual cortex to the spatial frequency of stimuli, a method based on wavelet packet entropy of local field potential is proposed. By doing experi-ments on Long Evans rats, both statistical analysis based on spike per second and analysis based on wavelet packet entropy of LFP are used, the result is that under stimulus of different spatial frequencies, tuning curves of wavelet packet entropy is consis-tent with tuning curves of spikes in whole, which indicates that the wavelet packet entropy of LFP can be used to measure the spatial frequency selectivity of neurons in visual cortex. The results also suggest better consistency when using wavelet packet entropy of LFP.关键词
