The Private Life of a Brain SurgeonThe Private Life of a Brain Surgeon
All In The Mind
Katrina Firlik's business is brains. Carving into the 'flesh of the soul' is her day job. The first woman admitted into one of the most prestigious neurosurgery programs, she's just penned an insider's account of her world. Part mechanic - part scientist, her intimate encounters of diseased and damaged brains offer a unique, and grisly, lens onto our most mysterious and wondrous organ.

Brains, Banter and Big Questions with Katrina Firlik
Episode Overview
- Neurosurgeons work as both scientists and mechanics, relying on feel, routine and tools as much as theory.
- Brain texture and consistency help distinguish normal tissue from damaged areas such as tumours or stroke.
- Major ethical decisions arise around elderly or severely impaired patients, where outcomes and quality of life are uncertain.
- Personality and behaviour can worsen or improve after surgery, highlighting how closely identity is tied to brain function.
- Future brain stimulation techniques may be used not just for disease, but potentially to enhance cognitive abilities in healthy people.
“"The brain is the individual. That's what makes us a person. And so if we're missing the thinking part of our brain, we're not left with much."”
What makes a recovery story truly inspiring? Here, the focus isn’t alcohol or drugs, but the organ that shapes every habit, craving and decision: the human brain. This episode of *All In The Mind* follows neurosurgeon Katrina Firlik into her operating theatre, where "the brain is my business" and everyday work involves what she calls the "flesh of the soul". You’ll hear Katrina describe brain surgery as part scientist, part mechanic.
She talks frankly about drills, tubes and "bone dust", alongside big questions about identity, personality and what makes someone truly themselves. Her anecdotes range from light-hearted moments, like a colleague being told off for playing Eminem during surgery, to unsettling cases involving maggots, massive strokes and babies born without the thinking parts of the brain. Host Natasha Mitchell keeps the tone surprisingly relaxed and witty, even while the conversation brushes against death, disability and ethical grey areas.
Katrina explains how routine and repetition are crucial for brain surgeons, why texture and feel matter when distinguishing healthy tissue from tumour, and how she sometimes meets her patients only as anonymous bodies on a stretcher before learning who they are later from family photos. For anyone interested in addiction and recovery, this is a reminder that behaviour and choice sit on top of fragile biology.
Katrina’s stories about personality changes from frontal lobe tumours, her scepticism about life after death, and her vision of future "brain enhancement" raise awkward but important questions: if we could tweak the brain like we tweak our appearance, what might that mean for people fighting compulsive behaviours? This episode suits curious listeners who enjoy science mixed with human stories, who aren’t squeamish about medical detail, and who like their big questions about the mind grounded in real-life hospital experience.
It might leave you asking: if the brain shapes everything you do, how are you looking after yours today?
