- A Western-led research study has found a correlation between poor diet and cognitive decline leading to memory loss.
- The study describes the critical importance of perineuronal nets, or PNNs which are structures that enmesh certain neurons in the brain.
- The study looks at how PNNs protect the neuron and regulate how often the brain turns experiences into memories.
- Amy Reichelt, a BrainsCAN Postdoctoral Fellow, along with Schulich School of Medicine & Dentistry neuroscientists Lisa Saksida and Tim Bussey, investigated PNNs to find out what effect they have on the brain and what happens when they’re not working.
- Structurally, PNNs form mesh-like webs around neurons in the brain. When working properly, PNNs protect neurons and synapses from toxins by forming a physical barrier or a shield around the neuron. PNNs also control the plasticity of these neurons by regulating the stimuli that could influence them.
- However, if malfunctioning or nonexistent, neurons without PNNs might be influenced by all experiences, potentially resulting in memories of irrelevant information. This abnormal plasticity has been connected to neurodegenerative and neuropsychiatric disorders including anxiety disorders and drug addiction. Reichelt’s work has shown that PNNs and the neurons they encase can be damaged by poor diets.
- Excessive consumption of junk foods high in saturated fats and refined sugars can cause toxic inflammation and oxidative stress in the brain resulting in cognitive decline and poor memory. This shows that diet and lifestyle may have an impact on other elements of the brain like PNNs, and not just the neurons.
- Reichelt’s research also demonstrates that certain lifestyle factors, including exercise or environmental enrichment, might improve cognition by naturally modifying the PNNs. The study was published this week in the journal Trends in Neuroscience.
- An old tobacco plant in Aylmer is being rebranded as a new cannabis plant. Construction is underway on a $2-million cannabis oil extraction facility in the Elgin Innovation Centre (EIC), located in the former Imperial Tobacco plant on John Street in Aylmer.
- The company, Motif, will occupy a 2,000-square-metre space that will employ up to 50 workers when it’s operational in the fall. Motif will be the 25th business to set up shop in the 93,000-square-metre complex left vacant after Imperial Tobacco moved out in 2008.
- Company co-founders Mario Naric, a former engineer with Imperial Oil, and Ian Haase, the former director of student entrepreneurship at Western University, explored a handful of locations in London before finding the perfect fit in the Elgin Innovation Centre.
- Motif is the second cannabis company to move into in the innovation centre. In 2016, WeedMD started growing marijuana in an 8,000-square-metre building that the company has since bought.
- Marijuana companies across Canada are preparing for the introduction of cannabis-infused edibles, extracts and topicals – products will become legal no later than Oct. 17.
- The market for alternative cannabis products like food, drinks and topicals could be worth as much as $2.7 billion annually.
- Yesterday, Rory McIlroy won the RBC Canadian Open in his first time competing in the tournament. The world number 4 golfer came into the final round tied for the lead at 13-under, and put a masterful final round together, shooting a 9-under 61, and had a chance to shoot a 59 later in the round.
- It is McIlroy’s second win of the season, and his 16th career PGA Tour win. It is also the sixth national championship he has won, having already won the US, British, Hong Kong, Australian and Irish Opens in his career.
- This year’s Canadian Open was a roaring success, seeing increases in ticket sales, attendance, and most importantly, beer sales. Next year’s tournament will be played at St. George’s Golf and Country Club in Toronto, while a handful of the competitors this weekend will have a quick turnaround before the US Open in California this coming weekend.
- Today will see a high of 19 with showers all day long, but it could clear up a bit this evening with the temperature hovering around 14 degrees.
- Tomorrow will be a high of 21 with a mix of sun and cloud.
- Wednesday will be pretty much identical with a high of 21 and partly cloudy.
