Scientists Find How Brains Keep Track of Time

Keeping track of time and remembering things that happened in the past is one of the brain’s most important functions. A recent study has identified the neurons in primate brains that code time.

Neuroscientists have theorized that the brain “time stamps” events as they happen, allowing us to keep track of where we are and when past events occurred. Scientists were not able to find evidence that such time stamps existed. But a study at the Massachusetts Institute of Technology (MIT) has now found that missing evidence.

Scientists Find Way to Reverse Insomnia-Induced Cognitive Impairment

Sleep deprivation affects cognitive function and learning and memory are the cognitive functions most affected by lack of sleep. Scientists at the University of Pennsylvania have identified a molecular pathway in the brain that causes the cognitive impairment due to insomnia. They have also found that by reducing the concentration of a specific enzyme that builds up in the hippocampus, they can reduce the inability to focus, learn or memorize that is symptomatic of sleep deprivation.

Different Types of Learning at a Molecular Level

A study conducted at the Montreal neurological institute and Hospital of McGill University has shown that training that occurs over time differs from training that takes place at short intervals and creates different types of memory.

Memory is very sensitive to not only the amount of training but also the pattern or frequency of training as well. It was found that training that was widely spaced generated long-term memory while intense training presented at short intervals generated short term memory.

NFL Players Have a Higher Risk for Alzheimer's

 A study by the University of Michigan’s Institute for Social Research, that was commissioned by the National Football League has found that NFL players are 19 times more likely to be diagnosed with Alzheimer’s or other memory-related diseases than the rest of the population.

Hundreds of on field concussions happen every week in high school, college and pro games. Many of these concussions go undiagnosed and untreated. The brain trauma associated with the concussions may be a contributing factor to the high rate of memory-related diseases.

Chemotherapy Affects More Than Memory

Although chemotherapy saves the lives of millions of cancer patients each year, it takes a significant toll on the cognitive function and emotional lives of the survivors.

Male Brains and Female Brains: Nature or Nurture?

Scientists have established that there are definitely anatomical differences between male and female brains. Are these differences caused by male/female behavior or do these differences cause the male/female behavior?

Using sophisticated MRI scanning, Peg Nopoulos, Jessica Wood and colleagues at the University of Iowa have been trying to shed light on the nature vs. nurture conundrum.

Children, Bilingualism and Brain Plasticity

Studies have found that the best age to learn a language is between birth and 7. This leaves most of the population out of learning a second language well enough to be considered a native speaker. Scientists have been looking into why children are able to learn languages so quickly and whether there is any way to apply the ability to adult language learning.

Obesity and the Brain

It is known that obesity and overweight take their toll on our bodies- increased risk of heart disease, diabetes, hypertension and cancer. Now there is scientific evidence that obesity and even overweight have a detrimental effect on our brains as well. Recent research has shown that obese people have 8% less brain tissue than people who are of normal weight and overweight people 4%. The brains of obese people looked 16 years older than the brains of people who were lean, and overweight people’s brains looked 8 years older.

Do Your Brain A Favor… Take A Nap!!

Some people think that napping is a waste of time and is an indication of a sleepy mind, but clinical research has shown that not only is napping good for you but that lack of sleep is harmful.

Regular napping is especially beneficial for memory. In addition, research has shown that napping:

• Restores alertness, memory and mood in young people as well as older people.
• Improves memory consolidation better than caffeine.
• Can heighten energy levels and improve performance if done before activities such as studying.

Reversing Age-Related Cognitive Decline

I’ve noticed that as people begin to experience age-related cognitive decline, they naturally start wondering about how much of it is normal and how much is reversible. Well, the bad news is that it’s inevitable and perfectly normal, and the good news is that you can do something about it.
