trigger a reflex that causes vasoconstriction when the right atrial transmural pressure (RATP) decreases and vasodilation when RATP increases.
The aging process is associated with alterations in autonomic cardiovascular control, leading to reduced vagal tonus, increased sympathetic tone, and attenuation of autonomic regulatory mechanisms such as baroreceptors
(33) and endothelial dysfunction, which may lead to a decrease in vasomotor tone and blood flow due to the dysfunction responding positively to nitric oxide, in addition to its reduced synthesis (1,31).
Incremental evidence indicates that the NTS is involved in mediating the central interaction between baroreceptor
and somatosensory receptor inputs [13,14, 36, 37].
In epileptic patients with drug refractory seizures who underwent intracarotid amobarbital injections (wada test), it was noticed sympathetic tonus predominance in the right hemisphere and parasympathetic predominance and up-regulation of baroreceptor
sensitivity in the left hemisphere .
However, it is extremely rare for multinodular goiter to cause carotid baroreceptor
hypersensitivity leading to symptomatic sinus pauses and bradycardia.

reflex (BRR) is another method that can be used for detecting CAN.

The following description begins with the baroreceptor
reflexes and follows the natural flow of the three sub-systems.
The medication was shown to improve standing heart rate, standing blood pressure, and baroreceptor
sensitivity (Kanjwal et al., 2012).
An implantable device for the bilateral electric baroreceptor
stimulation that decreases the sympathetic tone alleviates the obesity associated hypertension in experimental and clinical settings (Lohmeier et al 2012; Biaggioni 2012).
The MobiusHD System capitalises on the ability of the body's baroreceptor
mechanism to regulate blood pressure.
