Correlation.between.MEG an. BOLD fMRI sign.ls in.uced by visual flicker stimuli

引用

仪器仪表学报 2007年第4期28卷 577-582页

作者： Chu Ren.in.Holroyd tom Duyn.Jeff Departmen. of Radiology Harvard Medical School Boston Massachusetts USA MEG Core Facility National Institute of Mental Health National Institutes of Health Bethesda Maryland USA Advan.ed MRI section LFMI National Institute of Neurological Disorders and Stroke National Institutes of Health Bethesda Maryland USA

The goal of this work was to in.estigate how the MEG sign.l amplitude correlates with that of BOLD fMRI. To in.estigate the correlation.between.fMRI an. macroscopic electrical activity, BOLD fMRI an. MEG was performed on.the same subjects (n.5). A visual flicker stimulus of varyin. temporal frequen.y was used to elicit n.ural respon.es in.early visual areas. A stron. similarity was observed in.frequen.y tun.n. curves between.both modalities. Although, averaged over subjects, the BOLD tun.n. curve was somewhat broader than.MEG, both BOLD an. MEG had maxima at a flicker frequen.y of 10 Hz. Also, we measured the first an. secon. harmon.c compon.n.s as the stimuli frequen.y by MEG. In.the low stimuli frequen.y (less than.6 Hz), the secon. harmon.c has comparable amplitude with the first harmon.c, which implies that n.ural frequen.y respon.e is n.n.in.ar an. has more n.n.in.ar compon.n.s in.low frequen.y than.in.high frequen.y.

The presen. study evaluates the poten.ial of a bio-in.pired pulsation.damper in.a van. pump used in.mobile hydraulic ap- plication.. Pressure pulsation. caused by such positive displacemen. pumps can.lead to malfun.tion. an. n.ise in.a hydraulic system. A common.measure to reduce pressure pulsation. is the in.egration.of pressure pulsation.dampers down.tream of the pump. This type of dampin. measure can.also be foun. in.biology as e.g. in.the human.blood circulatory system. such workin. prin.iples foun. in.livin. organ.sms offer a high poten.ial for a biomimetic tran.fer in.o techn.cal application.. The n.wly developed bio-in.pired damper con.ists of cellular rubbers with n.n.lin.ar viscoelastic material properties. In.order to evaluate the n.w dampin. method, pressure pulsation. were measured at two differen. back pressures an. at a wide en.in. speed ran.e of the van. pump. For further assessmen., differen. setups, varyin. the stiffn.ss of the cellular rubber materials an. the damper volume, were tested. Within.the tested back pressures, the pressure pulsation. could be reduced by up to 40%. The developed in.egrated pulsation.damper offers a high poten.ial to dampen.pressure pulsation. of positive displacemen. pumps used in.mobile hydraulic application. ooeratin. below 10 bar.
