Unlocking the impact of early-life adversity on brain function
Do adults with a history of childhood trauma have altered brain responses to psychological challenges? Previous studies indicated that this can occur in laboratory animals, but it has been unclear whether it occurs in humans. Now a team of scientists, led by researchers from McGill University, have found evidence that exposure to childhood adversity is associated with an altered ability to process stressful challenges and other emotional material.

Seinfeld provides insight into how our brains understand and appreciate humour
If you have ever laughed at a joke despite not finding it funny, or laughed at something and weren't sure why, you have proven that comprehending and appreciating humour are two very different things. Western University neuroscientists have now discovered that two distinct parts of the brain trigger these reactions, a result that also may shed light on why some patients with Parkinson's disease might have difficulty being 'in' on a joke.

Animals like crickets use the ground to amplify calls: Western study
When animals 'sing' sitting on the ground- such as when crickets chirp- their volume and reach increase dramatically, by as much as ten-fold. This result from a study by Western researchers, published today in the high impact journal PNAS , contradicts long-held beliefs in the field of animal communication, which presume the ground is a hindrance to sound transmission.
