Abstract

This study was conducted at a medical university tertiary care hospital and research center of dedicated Parkinson and movement disorders unit in Hyderabad (South India) with a purpose to optimize projection of STN by applying M.E.R patterns analytically. 52 locally anesthetized Parkinson`s (diseased subjects/patients) underwent bilateral S.T.N-D.B.S. Concurrent M.E.R signal recording was done in a Ben’s-gun pattern setup with a 5core-pentode (5microelectrodes were set in an array scenario). Using spikes and circumstantial (or contextual) background-activity dissimilar parameters plus their phantom estimates in various-frequency-bands which include low-frequency(2Hz–7Hz), :Hz–12Hz, (sub-divided as low-) and superior :21Hz–30Hz and :31Hz-49Hz were computed. The ideal electrode implantation through better clinical-effect/dyskinesia ratio given to the peak spike-rate(S.R) in 86% of the implant. The amplitude mean-background activity in low-chucked frequency-range(FR) was analogous to right depth in 86% and right-hemisphere position in 95% of the implantation.
