  2. Hypertension and the brain - Wikipedia

    en.wikipedia.org/wiki/Hypertension_and_the_brain

    In terms of environmental factors, dietary salt intake is the leading risk factor in the development of hypertension. [7] Salt sensitivity is characterized by an increase in blood pressure with an increase in dietary salt and is associated with various genetic, demographic, and physiological factors— African American populations, postmenopausal women, and older individuals carry a higher ...

  3. Electrical brain stimulation - Wikipedia

    en.wikipedia.org/wiki/Electrical_brain_stimulation

    Electrical brain stimulation (EBS), also referred to as focal brain stimulation (FBS), is a form of electrotherapy used as a technique in research and clinical neurobiology to stimulate a neuron or neural network in the brain through the direct or indirect excitation of its cell membrane by using an electric current.

  4. Haemodynamic response - Wikipedia

    en.wikipedia.org/wiki/Haemodynamic_response

    This ultimately leads to a reduction in the haemodynamic response and less blood flow in the brain. This reduced cerebral blood flow not only kills neuronal cells because of shortages in oxygen and glucose but it also reduces the brain's ability to remove amyloid beta. In a healthy brain, these protein fragments are broken down and eliminated.

  5. Vasomotor center - Wikipedia

    en.wikipedia.org/wiki/Vasomotor_center

    G-series nerve agents have their most potent effect in the vasomotor center. [10] Unlike other parts of the body, where continued stimulation of acetylcholine receptors leads to recoverable paralysis , overstimulation of the vasomotor center is often causes a fatal rise in blood pressure.

  6. Electroconvulsive therapy - Wikipedia

    en.wikipedia.org/wiki/Electroconvulsive_therapy

    Placement can be bilateral, where the electric current is passed from one side of the brain to the other, or unilateral, in which the current is solely passed across one hemisphere of the brain. High-dose unilateral ECT has some cognitive advantages compared to moderate-dose bilateral ECT while showing no difference in antidepressant efficacy.

  7. Paralysis is determined by observing the extremity that the blood pressure cuff is placed on. The blood pressure is inflated to stop the effects of the muscle relaxant to a specific part of the body, allowing muscle to contract from the electrical current that is administered to the patient's brain.

  8. Electrophysiology - Wikipedia

    en.wikipedia.org/wiki/Electrophysiology

    Neuronal electrophysiology is the study of electrical properties of biological cells and tissues within the nervous system. With neuronal electrophysiology doctors and specialists can determine how neuronal disorders happen, by looking at the individual's brain activity.

  9. Baroreceptor - Wikipedia

    en.wikipedia.org/wiki/Baroreceptor

    The blood volume determines the mean pressure throughout the system, in particular in the venous side where most of the blood is held. The low-pressure baroreceptors have both circulatory and renal effects; they produce changes in hormone secretion, resulting in profound effects on the retention of salt and water ; they also influence intake of ...
