In a recent article in The Conversation, Joanna Fong-Isariyawongse, an associate professor of neurology at the University of Pittsburgh, explains that the brain responds to training in much the same way our muscles do. Clear thinking, focus, creativity, and good judgment grow when the brain is asked to stretch beyond its routine instead of running on autopilot.
Prof. Fong-Isariyawongse uses electroencephalograms, or EEGs, to study the brain’s electrical patterns. Research shows that when someone learns a new skill, these rhythms become more organized and coordinated. That slight mental discomfort we feel when trying something new is often a sign the brain is actually being trained, similar to the burn we feel during a good workout.
Below are key highlights from the article:
- Novelty drives growth. Repetition keeps the brain running, but novelty pushes it to adapt. Walking the same park loop every day eventually lets the brain check out, while taking a different path nudges it to pay attention again. Neuroplasticity thrives when the brain is pushed just beyond its comfort zone. Activities such as knitting, crocheting, or learning an instrument can improve cognitive abilities across a lifetime, especially when done in a group setting.
- Rest is part of the work. The brain has limits, and it does not get stronger from endless strain. When pushed too long without a break, attention and decision-making networks slow down while regions tied to rest and reward-seeking take over. This is why mental exhaustion often shows up as cravings for sugary snacks, comfort foods, or mindless scrolling, along with slower thinking and more mistakes.
- Sleep is the most powerful form of recovery. During sleep, the glymphatic system clears out waste and harmful proteins, glycogen stores are restored, and growth hormone surges to support repair. REM sleep helps the brain replay and consolidate the day’s patterns, locking in both mental skills like learning music and physical skills like a sports move.
- The brain stays adaptable for life. Cognitive resilience is not fixed at birth or locked in by early adulthood. It can be shaped at any age through small, consistent choices that signal to the brain that growth is still on the table.
Summing up, Prof. Fong-Isariyawongse highlights that building a sharper, more resilient brain does not call for a perfect plan or a breakthrough drug. The recipe is similar to building muscle: gentle challenge, novelty, and good rest, repeated over time. Even something as small as a different walking route can turn an ordinary routine into real brain training.
