It was pretty surprising when in 2014's study published in the American Journal of Preventive Medicine, Raji and his colleagues discovered consuming fish can enhance the physical size of the brain. Examining 260 subjects in their late 70s with no cognitive defects, the researchers found that the hippocampus-the learning centre of the brain-was 14% larger in those who ate fish weekly than in those who did not. The omega-3 fatty acids contained in fish also improved the performance of neurons in the brain's frontal lobe, an area that is crucial for executive functions like short-term memory and task planning. Now, fish may be the secret to heftier brains, but variety remains to be the spice of life. Here's how the latest research findings on human brain will help you improve your learning ability! Writing longhand trumps over typing on a keyboard
Though advances in technology have encouraged us to veer away from such old-fashioned analogue techniques, when it comes to absorbing new information, jotting things down by hand is markedly more effective than pounding away on a keyboard. According to published findings, the physical act of writing activates both our brain's sensorimotor and language centres. That element of motor memory is involved in recognizing the words on a page by sight; possibly meaning that the note you're making will leave a lasting visual impression in your brain. Writing "Pick up chicken" on a paper grocery list also takes longer than, say, tapping a chicken emoji on your smartphone, and that could affect retention as well. Your primary-school teacher may have been onto something when she made you write lines!Getting caffeinated boosts long-term memory
Mainlining espresso will keep you very alert, but recent research suggests that it'll also help your long-term memory. In 2014, scientists from Johns Hopkins University published the results of a test in which participants were given either a placebo or 200 milligrams of caffeine once they finished studying a series of pictures. The next day, after being shown more photos, the caffeinated group fared much better than their non-jittery peers at recognizing details that were similar (not identical) to the old series. That skill-known as pattern separation-suggests "a deeper level of memory retention," the researchers said. So the moment you learn something new, consider making a beeline for the a cafe around.
