The Podcast for Everyone with a Brain
Modern life can estrange us from what truly matters. We chase goals that look like success but feel hollow – and before we know it, we’re overwhelmed, reactive and disconnected from our own internal compass.
In this episode of Super Brain, Sabina Brennan explores meaning and purpose through a neuroscience lens and offers a powerful practical tool: make an appointment with yourself.
You’ll learn why your sense of self is essentially a story your brain constructed from data (some brilliant, some expired), why memory isn’t a recording device and how clarity changes what your brain notices.
By the end, you’ll have a simple, repeatable ritual to audit the story of you, update limiting beliefs and take one small action aligned with what matters most.

Episode Summary:
Why do some people seem to attract good fortune? In this episode, I explore the neuroscience of serendipity – those chance discoveries and happy accidents that change everything. From Alexander Fleming’s mouldy petri dish to the role of the brain’s default mode network in connecting unrelated ideas, this episode uncovers the science behind what we call “luck.”
You’ll learn how curiosity, openness, and cognitive flexibility make us more likely to notice opportunity when it crosses our path – and how to train your brain to do just that.

In this episode, Dr Sabina Brennan explores how generative AI changes learning. She looks at why effortful thinking is the engine of mastery, how AI can create an illusion of competence and practical ways to use AI as a tutor rather than a crutch.
Key takeaway: Learning sticks when it’s hard – AI works best when it helps you reach insights, not when it replaces the work.

If New Year’s resolutions leave you inspired one day and flattened the next, it’s not a willpower problem – it’s a nervous system problem. In this episode, Sabina shares three tiny, science-backed “micromoment” resets that help your brain feel safe enough to begin, plus a menu of quick interventions for common January traps like overthinking, doomscrolling, self-doubt, catastrophising, comparison, over-planning, worry and procrastination

Episode summary
What happens when you close your eyes and try to “see” something in your mind? For some people it’s a full-colour mental movie. For others it’s hazy, fleeting or completely blank. In this episode, Dr Sabina Brennan explores the neuroscience of mental imagery, including eigengrau (that grainy ‘intrinsic grey’ most people notice in darkness), the spectrum from aphantasia to hyperphantasia and why visualisation is less about forcing pictures and more about learning how your brain constructs experience.
In this episode, Sabina covers
Why “seeing nothing” when you visualise doesn’t mean you’re bad at imagination
Eigengrau – what that smoky grey tells us about baseline visual activity
Aphantasia and hyperphantasia – two ends of the imagery vividness spectrum
Mental imagery in brain terms: top-down simulation meeting bottom-up perception
Why worry is often a “mental movie” and how imagery can amplify emotion
How imagery is used in sport, performance, rehab and therapy
Tools in Three: how to work with imagery whatever your baseline
Key takeaways
Imagery varies hugely between people and it’s normal.
Visualisation isn’t just visual – sound, touch, movement, emotion and language can carry imagination too.
The goal isn’t perfect pictures, it’s intentional rehearsal that shapes attention, expectation and behaviour.
The most effective visualisation tends to be process-focused, not just outcome-focused.
Tools in Three
1. Know your baseline – stop forcing a cinema screen. Work with your strongest channel (words, sensation, sound, movement).
2. Build a multisensory practice – start with a real object, then recreate it with eyes closed. Add texture, temperature, weight, sound. Pair calming imagery with slow breathing.
3. Apply imagery intentionally and aim for process – rehearse the steps, the likely wobble moments and how you’ll recover, not just the “trophy scene”.
Memorable lines (pull quotes)
“Imagination isn’t about pictures. It’s about possibility.”
“Worry is often imagery too – the brain running mental movies of what might go wrong.”
“Aphantasia is not an imagination failure. It is a different format for thinking.”

Have you ever walked into a room and thought, “Any minute now they’re going to realise I’ve no idea what I’m doing”?
In this episode of Super Brain, psychologist and neuroscientist Sabina Brennan unpacks what’s often called imposter syndrome – and why the original researchers actually called it the impostor phenomenon instead.
Drawing on brain science and real-world examples, Sabina explores what’s happening in your threat circuits, reward system and perfectionist wiring when you’re constantly bracing for the “fraud police” to knock on the door. You’ll hear how early messages about being “the smart one” – or never quite smart enough – can set up a lifelong gap between how others see you and how you see yourself.
Most importantly, you’ll learn three practical tools to add to your Super Brain kit:
– Name it, don’t shame it – shifting from “I am a fraud” to “I’m having an impostor moment”
– Rewire the self-doubt circuits – using neuroplasticity, self-compassion and “good enough” experiments
– Change the context, not just yourself – noticing when your discomfort is data about an exclusionary system
The impostor phenomenon isn’t proof that you’re a con artist. It’s a protective brain story that you can gently update. You’re allowed to be a work in progress – and you’re allowed to be here while you’re learning.

Episode summary:
“Brain rot” was named the Oxford Word of the Year 2024 – a tongue-in-cheek term for that fried feeling after too much scrolling or streaming. But what’s really going on in the brain when constant digital stimulation leaves us feeling empty and unfocused?
In this episode, Dr Sabina Brennan unpacks the neuroscience of brain rot – how dopamine loops, cognitive overload and attention fatigue are reshaping our mental landscape – and what you can do to reclaim your focus and creativity.

Summary (short version):
Why does winter feel heavier for some of us? In this episode, we explore the neuroscience of Seasonal Affective Disorder — from circadian rhythms and serotonin pathways to evolutionary quirks and the strange possibility that humans may still carry traces of ancient hibernation biology. Learn why your brain struggles with short days, how morning light acts as a natural antidepressant, and practical strategies to help your winter self thrive.
I share my own experience with winter mood shifts, what the science says about why they happen, and — most importantly — the tools we can use to reclaim our energy and wellbeing during darker months.

Why are we so much harsher on ourselves than we are on others? In this episode of Super Brain, I explore the neuroscience of self-compassion — what it is, what it isn’t, and why it’s the antidote to self-criticism.
Drawing on the work of Dr Kristin Neff and Buddhist philosophy, we’ll look at self-compassion as a three-part skill: self-kindness, mindfulness, and social connection. I’ll share research showing how self-compassion reduces stress, quiets the amygdala, and activates brain regions linked to empathy and emotional regulation.
I’ll also explain why self-criticism is a form of self-harm, and why self-compassion is a foundation for flourishing and manifesting happiness, resilience, and contentment.

Psilocybin — the psychedelic compound in so-called “magic mushrooms” — has exploded into headlines and social media feeds. Some call it a miracle cure for depression, others dismiss it as hype. In this episode, I take a clear-eyed look at what the science really says.
I’ll start with Sarah’s story — a young scientist whose life was turned upside down by a cycling accident and who found hope again through a psilocybin clinical trial at Johns Hopkins. Her words: “This trial changed my life.”
From there, I explore:
Finally, I’ll share my Tools in Three so you can separate the real promise from the hype.
