The olfactory nerve otherwise called cranial nerve 1, is the first, and shortest cranial nerve in the body. It helps to send a signal of smell to the brain via its special afferent nerve. The olfactory placode is the origin of the olfactory nerve, and it provides supportive cells called the glial cells to provide […]
The Use of tENS in Pain Management
Transcutaneous Electrical Nerve Stimulation, shortly called TENS, is a procedure that involves electrically stimulating the sensory nervous system to provide a form of symptomatic pain relief through a pathway called the pain gate mechanism (1). Research suggests that the use of TENS brings about significant pain relief, opposing the also popular view that it acts […]
Gastroparesis – Symptoms, Treatment, and Vagus Nerve Stimulation
As you probably know, eating is one of the essential things in life. The ability to enjoy food often keeps us going when we’re feeling down or stressed out, and it can be a source of joy and comfort. However, eating can become frustrating and unpleasant if you have gastroparesis or another digestive disorder affecting […]
The Cranial Nerves
The cranial nerves are made up of twelve pairs of nerves with the origin at the back of the brain while passing the spinal cord (1). The cranial nerves serve as a connection between the brain and other parts of the body performing sensory and motor functions. The sensory functions are responsible for the sense […]
Vagus Nerve Exercise
What is the Vagus Nerve? The vagus nerve is the tenth nerve of the 12 cranial nerves, extending from the left and right side of the medulla oblongata section of the brainstem through the neck and thorax down to the abdomen. It is the longest and most complex of the cranial nerves. It is also […]
Vagus Nerve Diet?
There has not been much research into the relationship between diet and vagal nerve function or vagal tone. The word “vagal tone” refers to the efficiency with which your vagus nerve communicates with the different areas of your body. Electrical vagal stimulation has been the primary focus of most studies examining vagus nerve treatment methods. […]
Vagus Nerve Stimulation For Treatment Of Anxiety
What exactly is the vagus nerve?The Vagus nerve is the 10th and longest cranial nerve that constitutes the main component of the parasympathetic nervous system. This nerve is responsible for a wide range of important bodily functions, including heart rate, control of mood, digestion, immune response, and heart rate variability. Through the afferent fibers, it […]
What is Vagal Inhibition?
Vagal inhibition simply means the reduction of the functions of the vagus nerve to achieve some desired bodily effects. It is a type of neuromodulation which sends stimuli or impulses to inhibit the vagus nerve and hereby reduces the physiological functions of the vagus nerve. This type of treatment is used to alter and reduce […]
Vagal Maneuvers: 7 Techniques Used To Slow Heart Rate
Vagal maneuvers are known techniques used to increase vagal parasympathetic strength when trying to treat and diagnose different arrhythmias. Vagal maneuvers are safe and easily performed techniques mostly done first to differentiate SVT from ventricular tachycardias (VT) or terminate incidents of stable supraventricular tachycardia (SVT). (1) The heart contains two natural pacemakers called the sinoatrial […]
What Is Heart Rate Variability?
What makes the heart rate and its variability very unique? Heart rate variability simply means the measure of the variation in the time interval between each heartbeat in milliseconds. These fluctuations are usually undetectable except with specialized devices. This measure can be a sign of your overall health and well-being. HRV measures how uneven your […]
