  • Western neuroscientist Steven Laviolette and post-doctoral fellow Christopher Norris from the Schulich School of Medicine and Dentistry mapped how different regions of the brain produce significantly different reactions to marijuana use.
  • The research explores why some users experience euphoric highs while others experience negative psychiatric side effects including paranoia, cognitive problems and heightened risk of developing schizophrenia for others.
  • According to the research, both these experiences occur in the same part of the brain
  • The scientists looked at the effects of tetrahydrocannabinol (THC) – the psychoactive component of cannabis – on rat brains.
  • They found THC can produce highly rewarding effects in the region of the brain called the nucleus accumbens. THC in this area can also increase the addictive properties of opioid drugs like morphine, while also boosting reward-related activity patterns in the brain’s nerve cells.
  • Meanwhile, THC in the posterior area of the same brain region produced highly adverse effects, including schizophrenia-related cognitive and emotional symptoms and nerve cell activity similar to individuals with the psychiatric disorder.
  • The research shows that a specific area of the nucleus accumbens is more sensitive to THC and that may be a critical indicator of whether the user will experience positive or negative side effects from pot use. 
  • Until now, it was unknown which specific regions of the brain were responsible for these highly divergent effects of marijuana. 
  • Laviolette’s previous research has looked at whether cannabinoids – the more than 100 different compounds found in marijuana plants – can treat pain as effectively as opioids.


  • Yesterday was the last day of London’s Sunfest celebrations at Victoria PArk. 
  • Boosted by a visit from Prime Minister Justin Trudeau and blessed with glorious weather on its closing day, the 25th edition of Sunfest was a smashing success. 
  • Crowds flocked Sunday to Victoria Park to take in the music, food and culture under sunny skies with a high in the mid 20s C, a few degrees lower than the first three days of the world music festival.
  • More than 100,000 people attended the event that featured 40 performances and over 250 vendors. 
  • And if you didn’t get enough fun from Sunfest alone, you’re in luck — festival season is just ramping up in the Forest City.
  • Rock the Park will light up Harris Park this week with headliners such as Snoop Dogg and Pitbull. On July 19, the fun moves back to Victoria Park when the Home County Music and Art Festival kicks off its three-day run. In August, London Ribfest will run through the civic holiday weekend.
