Link between inflammation and mental sluggishness – Study

Scientists at the University of Birmingham in collaboration with the University of Amsterdam have uncovered a possible explanation for the mental sluggishness that often accompanies illness.

An estimated 12M UK citizens have a chronic medical condition, and many of them report severe mental fatigue that they characterize as ‘sluggishness’ or ‘brain fog’. This condition is often as debilitating as the disease itself.

A team in the University’s Center for Human Brain Health investigated the link between this mental fog and inflammation – the body’s response to illness. In a study published in Neuroimage, they show that inflammation appears to have a particular negative impact on the brain’s readiness to reach and maintain an alert state.

Dr Ali Mazaheri and Professor Jane Raymond of the University’s Centre for Human Brain Health, are the senior authors of the study. Dr Mazaheri says: “Scientists have long suspected a link between inflammation and cognition, but it is very difficult to be clear about the cause and effect. For example, people living with a medical condition or being very overweight might complain of cognitive impairment, but it’s hard to tell if that’s due to the inflammation associated with these conditions or if there are other reasons.” Continue reading

AI Examines how music makes us feel

Artificial intelligence helps shed light on how people’s brains, bodies, and emotions react to listening to music. Music influences parts of the auditory cortex, including the Heschl’s gyrus and superior temporal gyrus, specifically responding to pulse clarity. Changes in dynamics, rhythm, timbre, and the introduction of new instruments cause an uptick in the response. The study also identified the best song types for the perfect workout, sleep, and study.

Your heart beats faster, palms sweat and part of your brain called the Heschl’s gyrus lights up like a Christmas tree. Chances are, you’ve never thought about what happens to your brain and body when you listen to music in such a detailed way.

But it’s a question that has puzzled scientists for decades: Why does something as abstract as music provoke such a consistent response? In a new study, a team of USC researchers, with the help of artificial intelligence, investigated how music affects listeners’ brains, bodies and emotions.

The research team looked at heart rate, galvanic skin response (or sweat gland activity), brain activity and subjective feelings of happiness and sadness in a group of volunteers as they listened to three pieces of unfamiliar music. Continue reading
