Unraveling the complexity of 'Long-COVID' and its impact on breathing

More than a third of COVID-19 patients experience long-lasting symptoms, known as post-COVID-19 condition or long COVID, with breathlessness being a commonly reported symptom. Pulmonary complications, such as fibrosis and thromboembolic disease, require careful assessment, and non-pharmacological interventions like pulmonary rehabilitation can help manage breathlessness.

Researchers study canine brain networks in detail

A study on canine brain networks reveals that during mammalian brain evolution, the role of the cingulate cortex, a bilateral structure located deep in the cerebral cortex, was partly taken over by the lateral frontal lobes, which control problem-solving, task-switching, and goal-directed behavior.
