I’m angry. And I’m angry because I wish I knew this when I was younger.
So I’m a neuroscientist and a lecturer. And as a neuroscientist, I study the brain and the nerves that span out into the body. And as a lecturer, I teach the next generation of healthcare professionals.
And look, I see some students struggle with their learning, especially the older ones, but it’s not their fault. You know, we don’t get taught how to learn. We just kind of expect it to happen.
And I think the worst curse of all really is it gets harder to learn as we age.
But what if I told you that there are things that we can do to learn faster and more effectively?
I’m going to take you through the neuroscience behind six critical ingredients that can help you learn faster: attention, alertness, sleep, repetition, breaks, and mistakes.
How we learn: Neuroplasticity
Now, first things first. How do we actually learn? We need neuroplasticity to happen.
Neuroplasticity is the scientific term that essentially means our brain’s ability to physically change in response to experience.
So when we’re learning something, whether it’s learning information or learning a skill, tiny little connections called synapses form between neighboring neurons in the brain. And the more we do that thing, whether it’s information or a skill, the more robust those connections become and the better we get at doing whatever it is.
(Shows video of neurons connecting in a petri dish)
Now, what you’re looking at here are two neurons that I filmed in a petri dish connecting. Actually, this was a petri dish that I was about to throw away, but I saw they were about to connect, so I quickly took this video.
These incredible handlike structures here are called “growth cones,” and every neuron has one. They actively sense the environment around, and they help each and every one of the 86 billion neurons in your brain find the correct place to connect to.
This represents how our brain wires itself during development. When things go wrong with that wiring process, you can end up with issues with learning and memory.
Kids are like sponges — they learn languages, skills, sports quickly. Talent often comes from early and consistent practice (examples: Serena Williams, Beethoven started by age 5).
Our ability to learn goes downhill after age 5, gets harder through teens, and exponentially harder after mid-twenties. But there are things we can do.
1. Attention
In order to learn, we need to pay attention.
(Demonstrates attention by asking audience to focus on feet-floor contact)
We have the ability to choose how much attention we pay to something. Studies show full focus leads to better long-term retention.
We’ve never had to work this hard to pay attention before — social media, multitasking, scrolling causes measurable attention deficits (especially in teens using phone >1 hour/day).
Tips: Reduce phone use. Long-term: focused attention meditation. Short-term: 20 minutes moderate exercise boosts attention for ~2 hours (also increases hippocampus size, new brain cells, improves memory and cognition).
2. Alertness
(Air horn blast for demonstration — laughter)
To learn, you need to be alert. Activating sympathetic nervous system (fight-or-flight) releases adrenaline/noradrenaline, increasing alertness.
Ways: Exercise, Wim Hof breathing, cold shower blast, mild stressors.
Chronic stress harms learning/memory, but acute mild stress helps.
Caffeine before learning or regular use can enhance learning/memory.
Avoid studying after big meal (reduces alertness).
Ultradian rhythms: attention/alertness cycles ~90 minutes.
3. Sleep
Sleep is critical for memory consolidation — during sleep, brain replays and strengthens new connections.
Prioritize good sleep, especially after learning sessions.
4. Repetition
Repeating strengthens connections. Spaced repetition (over multiple days) is better than cramming (massed practice).
Two shorter sessions on different days > one long session.
Some things are learned in one trial if emotionally charged (e.g., traumatic events).
5. Breaks
Take breaks during learning (e.g., Pomodoro: 25-50 min work + break).
After intense learning, take 10-20 minute break (walk, no screens) — brain continues processing offline.
Spaced learning over days is key.
6. Mistakes
Making mistakes is powerful for learning. Errors grab attention, release neuromodulators, open window for neuroplasticity.
Challenge yourself, set up for failure sometimes, learn from errors — leads to better retention.
Don’t fear mistakes; embrace them.
Conclusion
Next time you learn: Minimize distractions, boost attention/alertness (exercise), repeat over spaced sessions, prioritize sleep, take breaks, embrace mistakes.
Thank you for your attention — hope you learned something!
