Tackling the science of [heterosexual] love is an interesting endeavour indeed. Lauren starts us off with the idea of three phases of love (lust, attraction, and attachment), the hormones and neurotransmitters associated with some of these phases, differences between men and women* and an evolutionary perspective on love. We then spend a good deal of time talking about attachment and what that kind of love means in parenting and with pet animals. We even talk about how the brain is affected by a break-up. Unfortunately, all we covered was heterosexual love.Read More
In a (school) year when marijuana became legal, how could we resist the temptation to discuss the neuroscience side of this popular drug. With this change in legislation here in Canada, it granted us the ability to have an open conversation about it, including some of our own personal experiences along with research related to two psychoactive ingredients: CBD (cannabidiol) and and THC (tetrahydrocannabinol). We covered both sides of this in terms the benefits and the negative side effects.Read More
In this week’s episode, we explore one of the most crucial aspects of the human experience; memory. We start off with a phenomenon Lauren finds particularly interesting: Highly Superior Autobiographical Memory, in which individuals can recall specific, extremely detailed aspects of their daily lives spanning years and even decades in the past. From there we discuss How do we store memories? What different facets and types of memory are there? What is going on with Alzheimer’s and Dementia. We also discuss some historical figures in memory research (e.g., H.M.), eye witness testimonies, place cells, and erasing memories.

Humans experience and observe some of the most extravagant wonders and marvelous sights the world has to offer using the sense many of us sometimes take for granted ; Vision! How do eyes work? What role does the brain play in all of it ? Can we trust what we see ? Find out in this week’s episode of the neuroscience podcast. Quite literally, there is more than meets the eye!Read More
For the second week of our Conversations with Neuroscience Students series, we discuss Nutrition and the Brain, which is a nice extension from what we talked about last week regarding Exercise and the Brain. There were many places we could have gone with this. What we did get into included the role of brain-derived neurotrophic factor (referred to as simply ‘BDNF' in the episode… and in neuroscience). We talked about toxins and diets and inflammation and even meandered into a discussion about social factors like food security and Canada’s new food guide.Read More
In this episode, we dive into the world of health and wellness and how exercise affects the brain. We explore concepts such as CBR (cerebral blood flow) and BDNF (brain derived neurotropic factor) to see how these are affected by exercise. We also talk about how exercise can affect different demographics and what significance it holds for illnesses like dementia and Alzheimer’s disease. We also share some of personal experiences with exercise and how it affects us and our studies.Read More
After a few years of students from the second-year neuroscience class I teach at the University of Guelph-Humber asking for how they can learn more neuroscience, I decided to take some of them on as part of their placement requirements. Here we will be exploring various topics in neuroscience. This is our first formal audio meeting where we hear from them, what they are interested in and give us some idea of how to proceed for the next couple of months working together.Read More
Sarah and I have been talking for a long time about her cancer but this conversation was planned as a way of starting her series of episodes for Mandyland. We had a bunch of ideas planned but realized early that it was hard to figure out where to start. So we started with why she has been hesitant to share this, despite her desire to. That got us talking about her career and the impact cancer has had on her career. From there we talk about where she is now and a brief introduction to her cancer. We end with how valuable it is to talk about stuff.Read More
Greer (another neuroscientist) and I began talking after I posted something on facebook about how I wanted to honour the female brain. She replied to my post with something like “YES!” and so we planned a conversation without any idea of where it would actually go. We went around and around and covered much ground including: 1) what does a woman leader looks like?, 2) valuing women in the workplace, 3) the female stress response of “tend and defend”and the maternal brain, 4) the difference between rearing boys' and girls’ brains and emotional brain development, 6) women’s intuition, and 7) the validation of #MeToo and #TimesUp. We wrap up with asking what are the characteristics of a female brain? We probably should have started with that, but we didn’t. We even tie in cryptocurrency. It ends a bit abruptly mostly because I deleted about 12 more minutes where we come up with a women's circle plan, which was interesting but a bit TOO much of a tangent. ;)Read More
