Dahl salt-sensitive rats rapidly become hypertensive when exposed to a high salt diet, but Dahl salt-resistant rats maintain normal blood pressure on a high salt diet. A defect in baroreceptor afferents is thought to play a key role in the low sensitivity of baroreceptor reflexes in Dahl salt-sensitive rats even in the prehypertensive stage during low salt treatment. In the present study, we te...

We investigated the distinct ability of various antihypertensive drugs to modulate the extent (%) of rapid (15 minutes) resetting of the baroreceptors of normotensive rats to hypotensive levels. In one protocol, hemorrhage produced a complete resetting to hypotension in rats chronically treated (6 days) with captopril. Also, hemorrhage produced only partial resetting in rats acutely treated (10...

The visual working memory (VWM) resetting process is triggered when the mapping between an object in the environment and its corresponding VWM representation becomes irrelevant. Resetting involves discarding the no longer relevant representations, and encoding novel representations and mappings. We examined how resetting operates on VWM's contents. Specifically, we tested whether losing only pa...

Tubuloglomerular feedback (TGF) and connecting tubule glomerular feedback (CTGF) are mechanisms that control afferent arteriole (Af-Art) tone. TGF, initiated by increased NaCl at the macula densa, causes Af-Art constriction. Prolonged activation of TGF leads to an attenuation or "resetting" of its constrictor effect. The mechanisms of TGF resetting remain incompletely understood. CTGF is initia...

The characteristics and extent of rapid or acute resetting of the aortic baroreceptors were studied in long-term renal hypertensive rats during 30 minutes of sustained hypertension produced by phenylephrine infusion. The aortic baroreceptors of hypertensive rats exhibited complete resetting to hypertension because during the control period the systolic threshold pressure for activation of the b...

Successful approaches to the robot localization problem include Monte Carlo particle filters, which estimate non-parametric localization belief distributions. However, particle filters fare poorly at determining the robot’s position without a good initial hypothesis. This problem has been addressed for robots that sense visual landmarks with sensor resetting, by performing sensorbased resamplin...

Stochastic resetting models diverse phenomena across numerous scientific disciplines. Current understanding stems from the renewal framework, which relates systems subject to global their non-resetting counterparts. Yet, in interacting many-body systems, even simplest scenarios involving give rise notion of local resetting, whose analysis falls outside scope approach. A prime example is that di...

The phase-resetting response of a model of spontaneously active cardiac Purkinje fiber is investigated. The effect on the interbeat interval of injecting a 20-ms duration depolarizing current pulse is studied as a function of the phase in the cycle at which the pulse is delivered. At low current amplitudes, a triphasic response is recorded as the pulse is advanced through the cycle. At intermed...

We investigated the effect of sodium nitroprusside, verapamil, and hemorrhage on the resetting of the aortic baroreceptors of normotensive control rats to hypotension, and the reversal of resetting of baroreceptors of one-kidney, one clip hypertensive rats to normotension. Using whole-nerve recording, the extent (%) of resetting (or reversal of resetting) observed 15 minutes after a maintained ...
