This chapter focuses on different types of biological and nonbiological artifacts in MEG and EEG recordings, and discusses methods for their recognition and removal. Examples are given of various physiological artifacts, including eye movements, eyeblinks, saccades, muscle, and cardiac activity. Nonbiological artifacts, such as power-line noise, are also demonstrated. Some examples are given to illustrate how these unwanted signals can be identified and removed from MEG and EEG signals with methods such as independent component analysis (as applied to EEG data) and temporal signal-space separation (applied to MEG data). However, prevention of artifacts is always preferable to removing or compensating for them post hoc during data analysis. The chapter concludes with a discussion of how to ensure that signals are emanating from the brain and not from other sources.

Objectives: To determine the effect of ovarian autotransplan-tation on decreasing FSH level in Wistarrats late menopause model.Materials and Methods: Experimental analytic research on 27 Wistar rats (Rattus novergicus) was divided into 3 groups. Group 1 (K1) or control. Group 2 (K2) performed bilateral oophorec-tomy without autotransplantation. Group 3 (K3) performed bilateral oophorectomy with autotransplantation. Measurements of FSH levels were performed on the first day, day 28 (four weeks after bilateral oophorectomy, during late menopause) and 56 day (four weeks after autotransplant). Measurement of FSH levels using ELISA. Data analysis used ANOVA and Post Hoc test.Results: The mean FSH level measured on day 56 at K1 = 63.400 ng/mL, at K2 = 78.416 ng/mL and K3 = 31.991 ng/mL. There were significant differences between K1 and K2 (p = 0,000), K1 and K3 (p = 0,000), and between K2 and K3 (p = 0,000).Conclusion: Ovarian autotransplantation decrease FSH levels in Wistar rats late menopause model.

P197 Background: Magnesium sulfate (MgSO4) has attracted interest as a neuroprotective agent during cerebral ischemia. Passage of Mg ion into the CNS has been poorly examined. The present study assessed the passage of ionized (physiologically-active)Mg into the cerebrospinal fluid (CSF) of patients with intracranial hypertension after MgSO4 infusion. Design: After IRB approval, patients requiring CSF drainage received IV MgSO 4 (5g)in 125 cc NS over 30 min. Plasma and CSF samples were taken hourly for 4 hrs. Intraventricular catheter placement was confirmed by CT. Data analysis involved ANOVA followed by Dunnet’s post hoc test for a significant F statistic (p < 0.05). Results: Nine patients (5/4, male/female; mean age=52) with closed head injury (n=3), subarachnoid hemorrhage (n=2), intracerebral hemorrhage (n=2), hydrocephalus (n=1), and subdural hematoma (n=1) were studied. Mean (±SD)Mg values are presented (table). Baseline Mg was higher in CSF. Although plasma Mg increased, CSF Mg was unchanged. Conclusions: Although the CSF to plasma Mg gradient is maintained in patients with intracranial hypertension, intravenous infusion of 5g MgSO4 does not further increase CSF Mg. This suggests systemic infusion of MgSO4 may not be an effective route of administration for neuroprotection.
