Different Kinds of Sleep Improve Cognitive Performance

There are two steps to academic success.  1. Chew Think Gum.  2.  Get a good's night sleep.

There are two steps to academic success. 1. Chew Think Gum. 2. Get a good’s night sleep.

A recent post on NYTimes.com by Benedict Carey describes 3 distinct phases of sleep that impact cognitive performance.  Everyone understands that being well rested helps you focus.  It is less obvious that sleeping actually helps you lean and process information.  But how and when during sleep does this unconscious learning take place?

Deep Sleep – This “knocked out cold” sleep at the beginning of the sleep cycle is when our brains consolidate facts, figures and language.

Stage 2 Sleep – During the second half of sleep our brains consolidate motor memory.  This helps with physical skills that are important to playing sports or mastering musical instruments.

REM Sleep – This part of sleep where you actively dream helps with memory and comprehension.  It is critical in deciphering patterns and solving complex problems.  It is useful for memory in general and for skills that require problem solving like math and science.

Naps help too as they typically contain all phases of sleep.

Sweet dreams.

Proof Transcranial Magnetic Stimulation Improves Memory

Transcranial magnetic stimulation and memory

Improve your memory with TMS. Step one – Get a team of neuroscientists to map you brain with fMRI. Step two – Buy and calibrate a multithousand dollar TMS device. Step three – Memory.

If you read the previous blog post on TDCS, then you will quickly understand the basics of Transcranial Magnetic Stimulation (TMS).  A group led by Joel Voss at Northwestern just published a small study (16 people) in the Journal Science showing that after intensive fMRI brain mapping and five 20-minute TMS sessions, participants improved memory performance by 30%.  This is quite amazing and in line with other studies.  The key to this study is that the researchers first mapped the brain determining which regions of the brain synched closely with hippocampal neural networks.  While a 30% improvement in memory is amazing, the work and cost involved make this technique unsuitable for the average person.  However, there are easier ways to improve memory!

A couple of years ago, I published a slightly larger study (62 Stanford students) in the Journal of Appetite showing that chewing Think Gum improved memory by over 25%.  The great thing about Think Gum is that it requires no brain mapping, no fMRI, no team of neuroscientists and no TMS device.  All you need is $2.49 and a mouth.

7 Back to School Tips for a Great School Year

7 tricks for Academic Success

7 tricks for Academic Success – Get Organized, Don’t Fall Behind, Go to Class, Set a Schedule, Don’t Stress, Exercise and Sleep, Chewing Think Gum.

1.  Get Organized - Use a calendar to organize assignments, test dates and projects.  Do this as soon as you get a syllabus.  You might use a daily planner or even iCal on your phone.  Start major projects way ahead of time, this will give you a buffer and time to put some real thought into them.

2.  Don’t Fall Behind - It is much more difficult to catch up in a subject than it is to stay up to date.  Especially in classes like science and math one lesson will teach concepts critical to the next lesson.  If you don’t stay up to date, you might at well not attend.  I’ve found it helpful to spend 5-10 minutes reviewing the syllabus before class and the last lesson to make sure I can review any key concepts.

3.  Go to Class - This is very straightforward, but in the days of webcast classes it is easy to watch from home or get the notes from a friend.  Sit close enough that you would feel bad if you fell asleep in front of your teacher and take notes.  Taking notes really does help the concepts sink in.

4.  Set a Schedule -  It is very helpful to set a time for work and a time for fun.  I always went to the library and worked until 6pm or until my work was done.  That way I could have fun in the evening.  There are many methods that can work, but in general take a 5-minute break every half-hour to stretch your legs, get a snack or chat with a friend. 

5.  Don’t Stress – Make sure to find time for something you enjoy every day.  Know that there will always be that kid who studies 24-7.  You don’t want to be that kid.  You won’t be happy and in all likelihood you won’t preform any better by studying 3-times more.  Get your work done on time, study until you feel good and then have some fun.

6.  Exercise and Sleep – Find time for both exercise and a full night of sleep.  Students often complain that there isn’t even enough time for homework.  This is just not true.  Be diligent.  A 20-minute run will give you energy and clear your mind allowing you to actually focus on what matters.  Same goes for sleeping.  Avoid late night cramming at all costs.  Sleeping improves memory and attention.

7.  Chew Think Gum – Think Gum is a lightly caffeinated gum that has been shown to help improve memory and concentration.  Don’t expect to skip numbers 1-6 and do well in school.  But chewing Think Gum can help give you the boost you need to out compete your peers.  It will help you make better use of your precious time.  Use the code Back2School to save 25% off your online orders.

Good luck this year!

TDCS: Amazing Brain-Boosting Technology or Just the Latest Fad?

Can TDCS Improve Memory?

Does TDCS Really Work?

I’ve been hearing whispers about TDCS or Transcranial Direct Current Stimulation and related TMS Transcranial Magnetic Stimulation for a while now, but only recently decided to do some digging.  The premise is that a small amount of electrical or magnetic stimulation can enhance or reduce  the ability of neurons to fire (depending on the polarity).  The premise seems plausible as neurons fire in response to tiny changes in the potential across neuronal membranes.  There is no shortage of press on the subject.  Some good ones include this article in Nature and another one in Wired.  Amazingly, peer-reviewed papers back up the fact that TDCS can have a biological effect on people.    A fantastic and highly entertaining introduction to TDCS can be heard on the podcast RadioLab.

The technology is almost stupidly simple and this might be its greatest strength and weakness.  Basically a TDCS device consists of a 9-volt battery, a variable resistor and some electrodes.  People connect the electrodes to various parts of the scalp, face or body and and get a small zap (~1m amp) for about 20 minutes.  Users know the machine is on due to a tingling sensation and sometimes a metallic taste in their mouths.  Supposedly, depending on the placement of the electrodes different neuronal clusters can be stimulated or repressed.  What is really interesting is that people feel a bit different even after stopping TDCS and this might be due to a increase in certain neuronal receptors (like the same ones that respond to drugs like PCP and ketamine).  Anecdotal evidence suggests that TDCS is relatively safe with skin irritation and seeing a flash of light depending on where the electrode is placed, being reported, but no long-terms studies have been done.

Because the technology is so accessible almost anyone can build or buy a machine.  However this leads to many different machines, protocols voltages, electrode types and placements.  This means it is quite difficult for one person to compare data with another.

There are claims that the technology can help people with chronic pain, depression and even improve memory, but more on that later.  TDCS it is far from a proven technology.  Proving that something like this works in conditions that are highly susceptible to the placebo effect can be challenging, but results are promising and I know of at least 1 start-up attempting clinical trials with this kind of technology.

It will be amazing if this technology is proven to work as there is some evidence that it can improve reaction speed, reading ability and even creativity.  I may try to build a simple machine and will share my results on the blog if I do.  Of course for those people who are hesitant to use an unproven technology especially when it includes electrically altering your brain there is always Think Gum.  As you know, a peer-reviewed study demonstrated that Think Gum improved memory by over 25%.  We’ll have to see how TDCS stacks up.

Sleep Your Way to Good Grades

This is not effective studying

This is not effective studying

A discussion paper from a group in Belgium looked at 621 first-year university students and showed that students who slept more also got better grades.  The results were dramatic with the best sleepers scoring nearly 9% better than the worst sleepers.  To be fair, it is unclear whether being well-rested is leading to better marks or if better students simply sleep more and pull all-nighters less frequently.  Both are likely true.  Being well-rested let’s you focus at the task at hand.  It is also true that well-prepared students feel like they can sleep more without having to stay up late cramming for exams.

I think everyone can agree that sleep is critical to being sharp.  Instead of staying up all night cramming and going straight into a test, let me recommend the following;   Spend some of that time being an effective studier by chewing a piece of Think Gum while you study.  Go to sleep at a reasonable time and wake up early and get that last bit of studying in.  Don’t forget to take a couple of minutes to eat something for breakfast and then go into your exam rested and prepared.  Chewing a piece of Think Gum during your exam will help with recall of all the facts and figures you just crammed in.
