In common with pacemakers, implantation of baroreflex activation therapy devices carries risks of bleeding, bruising and infection. [2] High stimulation voltages can cause an appreciable sensation which can be unpleasant. In typical use the device output voltage is adjusted to below the level that causes unpleasant sensations.

Flowchart showing baroreceptor reflex. The baroreflex or baroreceptor reflex is one of the body's homeostatic mechanisms that helps to maintain blood pressure at nearly constant levels. The baroreflex provides a rapid negative feedback loop in which an elevated blood pressure causes the heart rate to decrease. Decreased blood pressure decreases ...
Hormone secretions that target the heart and blood vessels are affected by the stimulation of baroreceptors. At normal resting blood pressures, baroreceptors discharge with each heart beat. If blood pressure falls, such as on orthostatic hypotension or in hypovolaemic shock , baroreceptor firing rate decreases and baroreceptor reflexes act to ...
High pressure receptors or high pressure baroreceptors are the baroreceptors found within the aortic arch and carotid sinus.They are only sensitive to blood pressures above 60 mmHg.
The carotid sinus baroreceptor can be oversensitive to manual stimulation from the pressure applied at the carotid sinus at the carotid bifurcation. It is a condition known as 'carotid sinus hypersensitivity' (CSH), 'carotid sinus syndrome' or 'carotid sinus syncope', in which manual stimulation causes large changes in heart rate and blood ...
Three patients whose lower bodies were left completely paralyzed after spinal cord injuries were able to walk, cycle and swim using a nerve-stimulation device controlled by a touchscreen tablet ...
The device stimulates the nerve, which in turn sends electrical pulses to areas of the brain associated with mood regulation. In the 12-month randomised control study, the device was implanted in ...
To ward off dementia, older adults may want to spend more time reading, praying, crafting, listening to music and engaging in other mentally stimulating behaviors, a new study says.
