Article Synopsis
- - Breathlessness is processed in the brain, particularly in regions like the insular cortex and amygdala, indicating that it involves more than just physical symptoms.
- - Treatments like inhaled L-menthol and blowing cool air on the face can relieve breathlessness without improving breathing patterns, suggesting they may work through brain mechanisms rather than just physiological ones.
- - A review of 29 studies found that stimulation of the trigeminal nerve activates several brain regions associated with breathlessness, supporting the idea that these treatments may help by changing how the brain processes the sensation of breathlessness.
The perception of breathlessness is mechanistically linked to the awareness of increased inspiratory neural drive (IND). Stimulation of upper airway cold receptors on the trigeminal nerve (TGN) with TGN agonists such as menthol or cool air to the face/nose has been hypothesized to reduce breathlessness by decreasing IND. The aim of this systematic scoping review was to identify and summarize the results of studies in animals and humans reporting on the impact of TGN stimulation or blockade on measures of IND.

It is unclear if high-intensity-interval-training (HIIT) elicits moderate-intensity continuous training (MICT) or resistance training (RT). We hypothesized that HIIT would augment executive function more than MICT and RT.
