53: Firing and Wiring : An Overview of Neurotransmission

Think Twice Podcast ·

2025/12/12

Ever wonder what’s really happening when your brain ‘fires’? In this episode, we explore neurotransmission, the rapid electrochemical messaging system that lets your neurons talk to each other and to the rest of your body, to allow you to plan, think, move, perceive, etc. We unpack neurotransmitters, receptors, and the multiple layers of complexity in which neurotransmitters shape mood, memory, movement, and more.

Think Twice Podcast ·

2025/11/28

Varsity athletes face hundreds of head impacts each season, some big enough to cause a concussion, others so small they barely register. But science is suggesting that even these quiet hits that don't cause concussions may quietly reshape the brain. In this episode, we dive into the neuroscience of concussive and subconcussive impacts. We unpack what science is revealing about how the athlete brain changes and what this means for the future of sport, safety, and long-term brain health.Coljae Berry

Think Twice Podcast ·

2025/11/14

What if the key to healing the brain wasn’t in a pill or a surgery, but in a headset? By stepping into immersive digital worlds with virtual reality (VR), scientists are discovering new ways to enhance neuroplasticity. But with such power to reshape the mind, VR also raises big questions: how real should “virtual” therapy get, and who can access this kind of therapeutic strategy? Join us as we journey through the science, the promise, and the ethical puzzles of healing in a virtual world.This

48: Interviewing a 1906 Nobel Prize Winner

Think Twice Podcast ·

2025/10/17

Santiago Ramón y Cajal, awarded the 1906 Nobel Prize in Physiology or Medicine, is often called the “father of modern neuroscience.” Using only a microscope and his extraordinary artistic skills, he revealed that the brain is made up of individual neurons that communicate across tiny gaps. This discovery, known as the “neuron doctrine,” transformed how we understand the brain and laid the foundation for all of modern neuroscience. Cajal’s detailed drawings of a wide variety of neurons and

2025/09/05

What happens when you hand the mic to artificial intelligence and ask it to run a journal club? Can it replace us, scientific podcasters, in our efforts to make scientific papers more accessible? In this episode, we explore how AI breaks down a neuroscience paper. We’ll see how it summarizes the research, points out the big takeaways, and even tries to critique the study. Can a computer really capture the curiosity, skepticism, and creativity of human researchers or do scientists still do it better

44 : Neurodiversity : Breaking the Brain Mold

Think Twice Podcast ·

2025/04/25

Neurodiversity refers to the natural variation in human cognitive functioning, encompassing different neurological profiles like autism, ADHD, dyslexia, etc. Rather than thinking of these differences as medical conditions in need of treatment, the idea of neurodiversity shifts this ideology to think about these differences as a form of natural human diversity, each offering distinct perspectives and contributions to society. This framework calls for changes in both clinical and cultural narratives

Think Twice Podcast ·

2025/04/05

When you eat very few carbs or go for a while without eating, your body can change its main energy source. Instead of running on sugar from food, your body starts burning fat, producing another source of energy in the process: ketones. For many years now, ketones have been investigated for multiple health benefits, such as weight loss, but also for boosting energy, improving focus, and supporting brain and heart health. Some research even suggests ketones might help protect against diseases like

2025/03/28

Grad school defenses are the ultimate test of a researcher’s expertise, challenging students to defend their work (sometimes years worth of it!) before a panel of experts. But why are they so important? In this episode, we break down the purpose of various types of defenses, what makes them so nerve-wracking, and how they shape the next generation of scientists.Authors: Eve Racette, Elena Koning, Shima Hassanpour, Golnar Taheri Email: thinktwicepodcast@outlook.com Instagram:

2025/03/03

In neuroscience research, very small details can make a big difference in the results and in the way they are interpreted. If research conditions aren’t carefully optimized, studies can produce inconsistent or unreliable findings, and can stall research in specific fields for months, sometimes even years. By fine-tuning their research parameters, scientists can get clearer, more accurate insights into how the brain really works. In this grad student interview episode, we discuss why optimizing basic

2025/01/17

Brain Computer Interfaces (BCI) allow us to connect the brain directly to an external device. By implanting some electrodes in certain regions of the brain, we can record brain activity and connect it to a computer or prosthetic that can then carry out the action that is being decoded based on the neural activity. Cool, huh? But before we get carried away by all the potential these technologies have, its important to discuss what the current state of research truly is and what ethical considerations
