文摘

Original experimental method for assessing the head tissues’ frequency responses. Similar frequency responses (gain excluded), independent of source–sensor distances. Fractional computational models with few parameters for the synaptic current sources. Favorable comparison with kinetic/computational models for different synapses. Simulated LFP signals having the frequency characteristics reported in the literature.
