Let’s Get To Know The Vagus Nerve

What does the Vagus Nerve Affect?
Anatomy of the Vagus Nerve
Organs connected to the Vagus Nerve
Changes in the activity of the vagus nerve have long been associated with the onset of dementia and general cognitive decline. But recent studies have further show that stimulation of the nerve in healthy people improved memory performance; because stimulation activates regions of the brain which are important in the consolidation memories.
The vagus nerve plays an active role in regulating your heart rate. Other parts of the nervous system accelerate your heart rate while the vagus nerve is responsible for returning your body to a calm and relaxed state. Under activity in the nerve can lead to hypertension and depression.
Signals from the brain pass along the vagus nerve and control the action of your lungs as you breath. This is why you can stimulate your vagus nerve naturally with deep breathing.
Inflammation is a natural and necessary reaction to injury or illness, but excessive inflammation can cause many dangerous or harmful conditions such as rheumatoid arthritis or sepsis. The vagus nerve works to prevent excessive inflammation by alerting the brain to the presence of cytokines which then triggers the release of anit-inflammatory molecules that reduce the inflammation and maintain a healthy balance.
The expression "gut reaction" comes from the strong link between your intestine and your brain. However, the extent of this connection is only now being fully understood through scientific research. Communication between the guts and the brain obviously plays an important role in managing appetite and reducing obesity; but recent science has demonstrated that it also regulate general mood, cognition and immune function.
