Rahul Jandial Quotes
Here is the most powerful Rahul Jandial quotes:
Most of what happened yesterday, let alone last week or last year, is literally deleted from your brain at night.
Rahul Jandial
Rest, you call that? The brain never rests. So essential to life are the myriad activities the brain engages in during sleep that without it, we die.
Rahul Jandial
One thing we know that humans and other mammals do during sleep is to transform short-term memories stacked up during the day into memories that can last a lifetime.
Rahul Jandial
we are left with evidence that is modest, at best, to justify the use of moderate alcohol. What’s beyond doubt, on the other hand, is that more brains and lives are ruined by overuse of alcohol than by any other substance.
Rahul Jandial
Physical activity turns out to be one of the absolute best ways to maintain and even improve cognitive health.
Rahul Jandial
Beginning in early adulthood, dopamine levels, which affect both physical movement and reward-motivated behavior (in addition to a bunch of other things), decline by about 10 percent every decade.
Rahul Jandial
your brain cells use more blood when they’re hard at work, just like your muscle cells do when you’re running.
Rahul Jandial
super-agers tend to have stronger social networks on average than people whose cognitive performance declines normally.
Rahul Jandial
the neural basis of grit in the brain identified a tiny region in the right prefrontal cortex, which other studies have found to be involved in self-regulation, planning, goal setting, and thinking about how past failures could have been turned to successes.
Rahul Jandial
Studying the same material over and over again is far less effective at improving memory than self-testing
Rahul Jandial
the greater danger, by far, is when an older person becomes isolated and disconnected. So by all means, older adults can and should be encouraged to connect online. I’m confident studies will show that social media serves old folks well.
Rahul Jandial
Sleep is not a suppression of brain activity. Quite the opposite. Sleep calls on deep powers of the brain never used during wakefulness.
Rahul Jandial
Sleep is a firestorm of brain activity. Instead of taking in new information, our brain’s subconscious is occupied defragging, deleting, and storing the prior day’s doings for long-term retrieval; cleaning out bits and pieces of discarded brain schmutz; and presenting us with immersive 3-D virtual stories in which we are the star.
Rahul Jandial
the popular notion that sleep is a time for the brain to rest is just wrong. The only people whose brains are truly resting are those who are placed in a chemical coma
Rahul Jandial
fragmented sleep often felt worse than no sleep at all. And the morning after was still a full fourteen-hour work day that required as much focus as one could muster.
Rahul Jandial
high blood pressure in midlife is strongly linked to the risk of developing Alzheimer’s later in life.
Rahul Jandial
Being able to switch between two languages, the researchers concluded, improves a person’s ability to maintain focus and attention.
Rahul Jandial
You might be surprised to learn that fruit juice is almost as bad as soda. In fact, a 12-ounce glass of orange juice contains nearly as much sugar as a can of Coke.
Rahul Jandial
another medical condition known to seriously increase the risk of heart disease is now also known to wreak havoc with the aging brain. Diabetes — in particular the persistently high blood sugar levels of poorly treated diabetes — substantially raises the risk of dementia
Rahul Jandial
People who spoke more than one language developed symptoms of dementia about four years later than people who spoke only one.
Rahul Jandial
No example of the brain’s capacity for self-reinvention is better demonstrated than in how it responds to having its left or right half removed in an operation called a hemispherectomy.
Rahul Jandial
people with early signs of dementia tend to show the opposite problem: When trying to recall a long list of items, they are less good at going through each category. They move to another category before exhausting the first.
Rahul Jandial
the effects of caffeine on learning and memory are unclear, with most studies suggesting no direct benefit.
Rahul Jandial
the brain doesn’t actually sit inside the skull; it floats, protected by a natural shock absorber called cerebrospinal fluid, or CSF for short. CSF is produced at a rate of about two cups per day from inside the brain’s deep, hidden chambers: the ventricles.
Rahul Jandial
Those cells on the outer lining of the brain, by the way, are the most precious ones.
Rahul Jandial
Smokers were three times less likely to develop Parkinson’s disease than nonsmokers.
Rahul Jandial
emotional intelligence is the ability to “rein in emotional impulse; to read another’s innermost feelings; to handle relationships smoothly.” As ethereal and slippery as these qualities might seem, they have their basis in the brain — primarily in the frontal lobe.
Rahul Jandial
Nearly every millimeter of your body is penetrated by nerves that have been sent out from the brain.
Rahul Jandial
Sure, practice improves everybody’s skills, and it’s absolutely essential in some fields. But are gold medals at the Olympics handed out simply on the basis of how long the athletes practiced?
Rahul Jandial

Rahul Jandial
The benefits are due in part to the fact that a bilingual person’s brain must actively suppress one language when speaking another. Being able to handle that extra workload results in stronger overall control of attention.
Rahul Jandial
How do you build a human brain? Given about forty weeks from the time of conception, nature decided eons ago to have a central spot for cranking out the billions of necessary neurons and then sending each of them on their way to migrate outward toward their designated permanent location. This radial migration is an astonishing feat of biological engineering.
Rahul Jandial
Other organs can go hours without blood flow before their cells die, but neurons survive only a few minutes without blood.
