Changes in brain activity in two-way traffic

Changes in brain activity in two-way traffic

Dutch researchers said on Tuesday that inhaling diesel exhaust caused a stress response in the brain that could cause long-term damage to brain function.

  Previous research has found that very small particles of soot, or nanoparticles, can pass from the nose and stay in the brain.

However, this is the first time researchers have shown that this can alter brain activity.

  ”We can only speculate that these effects could mean long-term exposure to polluted air when entering the city, with high concentrations of particulates in the air.

“Professor Paul said.

  ”It is conceivable that the effects of long-term exposure to nanoparticles in traffic may interfere with normal brain function and information processing.

“Paul and his research team placed 10 volunteers in an diesel-filled room for an hour and observed their EEG and EEG.

Diesel exhaust levels are similar to burning roads and garages.

  After about 30 minutes, the brain wave pattern showed a stress response, illustrating changes in the processing of information in the cerebral cortex.

  Further research is needed to assess the clinical effects of reducing this stress response and whether it affects verbal and non-verbal comprehension or memory in the long run.

  However, the results do not seem to show yet another disadvantage of nanoparticles in vehicle exhaust, which is associated with an increased incidence of respiratory and cardiovascular diseases.
