Article Title: Spectral Changes in Motor Thalamus Field Potentials during Movement
doi: 10.1101/2024.09.11.24313483
Figure Lengend Snippet: (A) Macroelectrode recording from the VIM nucleus of the thalamus during overt hand movement (shown on EMG recording) in subject 15. (B) VIM Ring electrode and EMG recordings during imagined hand movement. (C) Averaged power spectral densities (PSD) from two VIM recording sites during overt and imagined hand movement. Significant low frequency band (LFB; <30 Hz) suppression was observed at both sites during both tasks, whereas broadband power (65-115 Hz) increased at the 5mm above target site, but not during imagined movement. (D) The LFB and broadband frequency r 2 values plotted on sagittal T1 MRI slice.
Article Snippet: Serial thalamic recordings during task performance were obtained at multiple evenly-spaced recording sites (2 or 3 mm apart) as a hybrid microelectrode/macroelectrode (AlphaOmega Sonus STR-009080-00) was advanced towards the inferior border of the thalamus ( ).
