Graduate
Miss
Misa Yoshimoto is a student in Ph.D. course of Graduate School of Humanities
and Sciences at Nara Womenfs University.
She graduated from the Faculty of Life Science & Human Technology at
Nara Womenfs University with a Bachelor degree in Food Science and nutrition in
2000. Then she entered the Graduate
School of Humanities and Sciences at the same University and received the degree
of Master of Science in 2002 under the Prof. K. Miki. Her major research interests
are in the neural regulation of cardiovascular function during exercise and
sleep and has published several papers in internationally peer-reviewed
journals.
Acute shift in baroreflex
control of sympathetic nerve activity during exercise and sleep.
The
arterial baroreflex is the primary closed-loop feedback mechanism participating
in short-term control of systemic arterial pressure. We demonstrated that
treadmill exercise shifted the baroreflex control of sympathetic nerve activity
upward and to the right and REM-sleep induced a vertical suppression of the
baroreflex curve. These data
suggest the baroreflex control of sympathetic nerve activity may be altered in
state-dependent manner. Functional organization of the state-dependent changes
in the baroreflex curve will be discussed.
