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
Sarah provides a spring update on where she's at with cancer. It's been a year since her metastatic cancer diagnosis. More scans, treatment protocols, surgeries, emotions, and science.Read More
Join me for a sitting meditation. Find your comfortable sitting position, close your eyes, focus on your breath, listen to me talk about impermanence and expectations in the context of anxiety. Then stay for silence together.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
This is a guided meditation practice with a focus on breath awareness. It's one of several basic introductory meditations to help build concentration skills with a focus on the breath.

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
I’m going to invite people into the process of my next project related to human intelligence and the need to rethink the way we see intelligence. In this first episode about it, I talk about Multiple Intelligence according to Howard Gardner and also about VIA Character Strengths. At the end, I invite people to take my in-progress screening survey on multiple intelligence and the VIA survey. The link for those are both listed below.
Take the VIA survey first so you can tell me what your top 5 character strengths are in my survey.
My First Draft of a Multiple Intelligence Survey:
My goal with all of this is to use a combination of questionnaire, interview by a trained coach, and if possible, field assessments. I will be looking for volunteers for the initial pilot testing. If you want to be considered, please do both the VIA survey followed by my survey and you may be contacted for follow-up.
Please note, this survey is not about identifying people as intelligent or not but rather about the hope of identifying individual’s dominant intelligence and strength.
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
In this episode, originally sent as a voice memo to Mandy and Mike, Sarah recounts the immediate aftermath of being kept up overnight by side effects of one of her treatments. This was back in September 2018, before recording the first podcast we published with Sarah on Mandyland. But she wants to share this note as it captures feelings of vulnerability, frustration, confusion, and exasperation that arise in dealing with cancer treatment. It's happened a few times now that a new symptom pops up and spurs a chain of medical appointments, scans, and tests. Figuring out what is going both in her own experience in her body, and from the perspective of multiple doctors, has proven to be one of the most challenging types of cancer experience. At present, Sarah's happy to report the small probably benign lesion for which this episode is named has not grown or caused any significant problems since it showed up, and her brain remains entirely healthy and tumor-free.Read More
Sarah and I are in San Diego, at the Society for Neuroscience Annual Meeting, a place we have been together many times. We had many slow(er than normal) days and quiet nights in our hotel room. And then we got a chance to really dive into what her new normal is. The conference was a perfect place to compare what use to be, with what is now.Read More
Mike and I got into a conversation about The Interoceptive Mind, a way of feeling our inner body provoked partially by a book that I picked up at the Society for Neuroscience back in November. According to the authors Interoception is “the body-to-brain axis of signals originating from the internal body and visceral organs (such as gastrointestinal, respiratory, hormonal, and circulatory systems).”Read More
Clearly, I have more important things to do with my time than creating episodes. Here’s a little snapshot into that. Note, this was recorded by Mike at the end of our date night, on Dec 1st. I only found out about it yesterday (Dec 9th). Apparently he sent it to me but I didn’t even see it or listen to it.
An introduction to focusing on the breath, a basic concentration practice that sets a foundation for meditating and for deepening your practice. Mostly instruction and practice, with a little bit of commentary on why we are meditating.
I reconnected with one of my favorite students from Ryerson. He was that super engaged student who asked good critical-thinking questions and really took things to another level. So when he contacted me to say he developed a game on scientific thinking, I was super excited to meet up and learn more about his game. And what he showed met my expectations. Jon is reflective, intelligent, a deep critical thinker, and a social justice advocate. All of these elements came out clearly in our conversation about his game “Think Like A Scientist!”. In an age where information is both a commodity and exploited, learning how to think like a scientist is even that much more important! It was a fun conversation where I decided to mostly keep my scientist hat on. I did challenge him a little bit on his bias against natural and the conflict of interest in science. We broached the topic but didn’t go to deep, because it was simply beyond the scope of this audio. ;)Read More

In this monologue, Sarah recounts her feelings over the past 3 years of dealing with cancer both how it looked from the outside and how it felt from the inside. At the beginning, she wondered "how am I going to come out the other side?” It felt like she was walking through a doorway in Alice in Wonderland and then suddenly stumbled upon the strange universe. She realized that the way that you look at the world shifts. And a big theme for her, is that cancer is slow.Read More
Today... I felt my existential depression... and am so glad I happened upon that term recently.
For reference, I was reading from the book A Parent's Guide to Gifted Children, by James Webb, Janet Gore, Edward Amend, and Arlene DeVries.
