What is the brainstem
The brainstem is a region of the brain that is located between the spinal cord and the cerebral cortex. It is responsible for controlling many of the body’s vital functions, including heart rate, blood pressure, respiration, and the reflexes of the cranial nerves. These brainstem reflexes such as pupil are responses to light, gag reflex, and eye movement with head turns. The brainstem is made up of several different parts, including the midbrain, the pons, and the medulla oblongata. It plays a crucial role in the regulation of the body’s autonomic functions, and damage to the brainstem can have serious consequences for an individual’s overall health and well-being.
HRV as a proxy for brainstem functionality
Heart rate variability (HRV) refers to the fluctuations in the time interval between successive heartbeats. HRV is influenced by the activity of the sympathetic and parasympathetic nervous systems, which are controlled in part by the brainstem. The sympathetic nervous system is responsible for activating the body’s “fight or flight” response, while the parasympathetic nervous system is responsible for the “rest and digest” response. The brainstem plays a role in regulating the balance between these two systems and in turn, influences HRV.
Studies have shown that HRV is related to the health of the brainstem and that individuals with lower HRV tend to have lower brainstem function. HRV can also be used as a marker of brainstem function and has been shown to be reduced in individuals with brainstem injuries or disorders. In general, higher HRV is associated with better overall health and well-being, while lower HRV is associated with an increased risk of health problems.
How we use HRV to optimize the brainstem
Using HRV as a benchmark we want to optimize the brainstem as a form of preventive medicine. This will be achieved through the provision of early diagnosis and digital therapeutic options. In doing so, Brainstem seeks to help to improve health care equity by finding smarter and more efficient ways to do things, while striving to improve health care outcomes for everyone.
