It is a myth that specific parts of the human brain have specific psychological jobs. The myth claims that the brain has separate parts, each with a dedicated mental function - one part for vision, another for memory, etc.
Today, we know the brain is a massive network of neurons with multiple jobs, not a single psychological purpose. Not all neurons can do everything, but most neurons do more than one thing.
This myth is the idea that the human brain evolved in three layers.
Modern research has revealed that the brain doesn't evolve in layers but is built from a manufacturing plan using the same neurons.
The idea that your brain reacts to events in the world is a myth. The idea supposes that you go through your day with parts of your brain in the off position, but when something happens around you, those parts become active and light up with activity.
But the brain doesn't work by stimulus and response. All your neurons are firing all the time at various rates. Your brain uses all its available information to predict what will happen next and make corrections outside of your awareness.
This myth states that there's a clear dividing line between the disease of the body, such as cardiovascular disease, and the disease of the mind, such as depression. Philosopher René Descartes popularized the idea that body and mind are separate.
But neuroscientists have found that the same brain networks responsible for controlling your body are involved in creating your mind. Every mental experience has physical causes, and physical changes in your body often have mental consequences.
Found on both sides of the mouth for some of us, cheek dimples are considered attractive and ‘genetically dominant’. Around 37 percent of the population are having cheek dimples (in a study of 2300 people).
Cheek dimples are caused by a change in a particular facial muscle called zygomaticus major. Genetics too play an important part for a face to have dimples, which can develop over a lifetime and also disappear.
Cheek dimples are associated with beauty and some cultures consider it a sign of good luck. They also help us communicate better and recognize the intensity of facial gestures in a person.
Some people also opt for surgery to get these cheek bends, something called dimpleplasty.
The amount of sugar that can be found in fruit juice is significantly higher than in fizzy drinks. Studies suggest that too much sugar can put us at risk for health problems such as obesity, diabetes, or tooth decay.
However, pure fruit juice does contain vitamins, minerals, and antioxidants that cannot be found in fizzy drinks. Generally, fruit juices are better for you in terms of warding off infection or inflammation and boosting your immune system.
Healthy circadian rhythms rely on regularity and stability— for the timing of light, the timing of exercise, and the timing of meals.
Our bodies are accustomed to the exposure of light and darkness on a regular basis. The circadian rhythm is reset on a daily basis and it is the one that determines the healthiness of our cellular health and sleeping patterns.
When you lack sleep, not only does your circadian rhythm go out of sync but it also further exacerbates difficulties with attention span, mood swings, and changes in memory.
Here are some things you can do to reduce your circadian instability:
Our body's proximity to water – large flowing rivers and the coastal regions, has been associated with positive effects on our health and wellbeing.
Just like being in nature is good for health, being near water is shown to be beneficial for the body and mind.
Seaside living generally has more sunlight and less pollution, promoting better health and more of vitamin D to the people living there.
People who are living near the sea also are more likely to spend time outdoors in some activity or exercise.
Water has a psychologically restorative effect on humans. It reduces negative mood and stress at a better rate than being in green spaces(nature).
Water is an immersive experience as we come in tune with the natural forces. The motion of the wind and the movement of water stirs our body and mind in a cognitive, positive way.
Most people have experienced a sensation where while being in a situation, event, or place, we feel as if we have already experienced the same. This sensation is called déjà vu, meaning ‘already seen’ in french.
Some say these are false memories or a past-life remembrance. Others state that it is a short circuit in our brain or some activity in the ‘rhinal cortex’ of the brain.
Scientists have studied this phenomenon in the lab using hypnosis and virtual reality, concluding it to be related to memory, where we experience a feeling of familiarity as the new experience seems to be traced according to an old memory.
A new study using MRI scans suggested that déjà vu is related to decision making, and the brain may be trying to resolve a conflict in the memory index.
The placebo effect happens when a person takes medication that he thinks will help, but the medication has not been proven to be effective for the specific condition.
Placebos work in about 30 percent of patients. Some placebos contain no active ingredient. Other placebos do have active ingredients but aren't proven to work on the patient's particular condition. There are even placebos in the form of surgery, injections, and other types of medical therapies.
When people know what the result of taking a pill is supposed to be, they might unconsciously change their reaction to cause that result or report that result has taken place even if it hasn't.
However, studies show that a placebo doesn't trick the brain - the brain reacts differently to a drug than a placebo. A 2004 study showed that the expectation of pain relief causes the brain's relief system to activate.
Placebos are often used in clinical drug trials to determine how well a potential medicine will work.
A 2007 study revealed that 45 percent of doctors had prescribed a placebo at some point. Doctors believed that placebos had a therapeutic effect.
The most commonly prescribed placebos are aspirin, vitamins, and antibiotics. Doctors prescribe placebos because they have no other form of relief to offer the patient. Other times, the patient insists on taking some type of medication.
The American Medical Association created a policy concerning placebos that states that "physicians may use placebos for diagnosis or treatment only if the patient is informed of and agrees to its use."
In exercise, carbohydrate-rich diets are often recommended to promote recovery and maximise performance.
However, research suggests such foods may not help exercise recovery. There is also a potential link with carbohydrate-rich foods and metabolic diseases.
Since late 1960, the energy status of muscles is deemed to be important in exercise performance.
Since carbohydrate is the preferred energy source for muscle contraction during intense exercise, sports nutrition guidelines recommend eating carbohydrate-rich food to maximise performance. The guidelines suggest eating one gram of carbohydrate for every kilogram of your body mass, each hour for four hours.
The current nutritional recommendations for performance may not be ideal for promoting recovery.
Researchers have recently observed that limiting carbohydrate intake close to endurance training sessions might promote early muscle recovery and possibly long-term improvements in endurance.
Consuming protein when doing resistance exercise is known to benefit muscle growth. Dietary carbohydrate plays little to no role in recovery from resistance exercise.
While high carbohydrate intake have traditionally been recommended to support resistance exercise performance and recovery, several studies now show that it does not further benefit recovery processes compared to protein alone.
Carbohydrates have a potential role in the development of metabolic diseases, including type 2 diabetes and obesity.
Carbohydrate-rich food is thought to overstimulate the hormone insulin by causing chronically high blood sugar levels. One of the roles of insulin is blocking the use of fats as a fuel source. Insulin also promotes the storage of excess carbohydrate as fat and reduces the body's ability to control blood sugar levels. Eating a high-carbohydrate diet may increase fat mass and decrease muscle mass.
You don't necessarily have to be the running type. Almost anyone can be a runner.
And with running, you don't need a membership, expensive equipment, or a qualified coach. You do need a good pair of running shoes to take care of your feet and knees. Other than that, wear what you feel good in.
Run slow enough that you're pretty sure you could overtake yourself at a brisk walk.
The point of running is endurance, and to manage that, you have to keep your heart rate elevated for the entire period of every training run. That means erring on the side of caution and only speeding up when you hardly break a sweat 20 minutes in.
Slowly build up stamina over the first few weeks and months. To start, run three times a week for eight weeks, beginning with sessions that involve more walking than actual running, and ending with 30 minutes of non-stop jogging.
