title: Electrophysiological characterization of human subcortical structures by frequency spectrum analysis of neural noise (field potential) obtained during stereotactic surgery. Preliminary presentation of frequency power spectrum of various subcortical structures.
abstract: Neural noise, or field potential, was recorded during stereotactic thalamotomy in 46 cases of various involuntary movement disorders. Frequency power spectrum analysis of neural noise from various anatomical substrates was performed, and the relationship between resultant frequency power spectrum and anatomical substrates, as defined by Schaltenbrand-Bailey's atlas, was examined. Frequency power spectrum was fairly characteristic for each subcortical structure.
