Researchers put brain training to the test.

Researchers from The University of Queensland have shown for the first time that “brain training” for specific tasks can also improve broader brain performance, in findings with major implications for ageing brains.

The team from the Queensland Brain Institute  and UQ’s School of Psychology studied the benefits ofbrain stimulation devices that deliver transcranial direct current stimulation (tDCS) via electrodes on the scalp.

QBI’s Professor Jason Mattingley said experiments applying tDCS to the left prefrontal cortex of the brain showed increased performance in both trained and untrained tasks.

Toxic air pollution nanoparticles discovered in the human brain.

Tiny magnetic particles from air pollution have for the first time been discovered to be lodged in human brains – and researchers think they could be a possible cause of Alzheimer’s disease.

Researchers at Lancaster University found abundantmagnetite nanoparticles in the brain tissue from 37 individuals aged three to 92-years-old who lived in Mexico City and Manchester. This strongly magnetic mineral is toxic and has been implicated in the production of reactive oxygen species (free radicals) in the human brain, which are associated with neurodegenerative diseases including Alzheimer’s disease.
