title: Signal processing methodology to study the cutaneous vasodilator response to a local external pressure application detected by laser Doppler flowmetry.
abstract: The existence of a cutaneous pressure-induced vasodilation (PIV) has recently been reported. This paper proposes a signal processing methodology to improve PIV knowledge. Temporal variations of laser Doppler signals rhythmic activities are first analyzed on anesthetized rats. The results lead to a method that provides a better PIV understanding.
