Core neurons in the lateral parabrachial nucleus project to the amygdala, an area of the brain associated with fear and emotional processing of pain. Neurons in the shell project to the pre-Bötzinger complex, a region that generates breathing rhythm. Both core and shell neurons influence each other according to inputs from each area, increasing breathing rate when we are in pain or anxious.
For the first time, researchers have successfully stimulated a human amygdala and recorded breathing loss. Their research provides important insight into SUDEP.
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 small study of patients with severe COVID-19 symptoms in Wuhan found laying face down was better for the lungs.
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.
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.
A groundbreaking study from Karolinska Institute researchers reports astrocytes play a key tole in the respiratory center of the brain stem and assist with the regulation of breathing. The findings are significant as they could provide clues to the causes of respiratory diseases.
By transplanting V2a interneurons, researchers improved respiratory function in mice with spinal cord injuries, a new study reports.
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.
