Show Notes
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. Three Tools for Your Super Brain Kit: Light before screens — Get bright light within 30 minutes of waking (10–20 minutes outdoors or a 10,000-lux lamp). Anchor your day — Keep wake and sleep times consistent to stabilise your circadian rhythm. Reverse-winter habits — Add small dopamine-rich rewards before difficult tasks, not after, to counter low motivation.
Each episode explores what’s really going on inside your brain when you do the things you do — from the everyday to the extraordinary — and gives you three tools for your Super Brain kit.

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. In This Episode Why meaning and purpose aren’t found by doing more How stress pushes your brain into survival mode Why your sense of self is a story built from old data The myth of memory as a “video file” How limiting beliefs are often narrative errors A step-by-step “appointment with yourself” ritual How clarity becomes a neural filter for what you want next Call to Action If this episode landed for you, schedule your appointment with yourself today – even 30 minutes is enough.

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: How the term serendipity was born from a Persian fairy tale What neuroscience reveals about “accidental” discoveries Why “lucky” people simply notice more (Wiseman, 2003) How creative insights emerge from brain network interplay (Beaty et al., PNAS, 2018) Why our digital lives might be shrinking our chances for serendipity – and how to get it back The Three Tools for Your Super Brain Kit to invite more insight, connection, and creative luck into your life Three Tools for Your Super Brain Kit: Expand your input – curiosity feeds connection. Practise attentive openness – notice what others miss. Reframe setbacks as openings – mistakes can be portals to discovery. Referenced research: Beaty, R. E. et al. (2018).

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. Source: Brian W. Stone (2025), The Conversation – “How does AI affect how we learn? A cognitive psychologist explains why you learn when the work is hard”. Support this show http://supporter.acast.com/superbrain.

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.
