A baby's first breath triggers a signaling system in the brainstem that helps support early breathing. The findings shed light on how problems with this neuropeptide system can increase the risk of SIDS.
Researchers say that to date, primary transmission methods of concern for coronavirus have been near field transmission via sneezing and coughing, and hand-to-face transportation of the virus after touching infected surfaces. They warn more attention needs to be paid to the inhalation of aerosols generated from breathing and talking.
On average, women have to work harder to breathe during strenuous exercise than men. The findings not only shed light on how sex may affect exercise dynamics but also the differences in how men and women experience airway disorders, such as asthma and COPD.
A small study of patients with severe COVID-19 symptoms in Wuhan found laying face down was better for the lungs.
Each breath begins with hundreds of individual neurons haphazardly firing at low levels, then quickly synchronizing. The synchronization prompts activity that signals diaphragm and chest muscles to contract, causing expansion and inhalation. As the signal subsides, exhalation occurs.
Researchers say serotonin, a chemical commonly associated with mood regulation, may play in breathing problems associated with epileptic seizures. Those who had higher levels of serotonin following a seizure than before the event were less likely to experience interrupted breathing.
An opinion article reports on a potential common cause for both SIDS and SUDEP. The reason sudden death may occur is due to a person's inability to wake when CO2 levels in the blood rise, as a result of dysfunctional serotonin neurons in the midbrain.
A new study reports acute loss of normal activity in serotonin producing neurons blunts the body's ability to recover from interrupted breathing. Researchers say this could provide an explanation to why some infants die from SIDs, and could someday help with the development of therapies to prevent sudden infant death.
