Assessing human brain impedance using simultaneous surface and intracerebral recordings

Highlights • 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 ki...

Description
Summary:Highlights • 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.
