People Excellent at Trivia might have Efficiently Wired Brains: Study

A small study carried out by the team of researchers from Ruhr University Bochum and Humboldt University Berlin, has shown that people with good knowledge might have really efficiently wired brains. 324 healthy people took part in the study in which the team of researchers used a number of different MRI techniques to study the structural and functional pathways of the brain.

The study also answered the question of whether interindividual differences in the brain’s structure and function are linked to interindividual differences in general knowledge or not. In the study, the participants were asked to complete a general knowledge test known as the Bochum Knowledge test. And a particular type of imaging known as diffusion tensor imaging was used to reconstruct the pathways of the nerve fibres and also various models were used to test the efficiency of the nerve fibre pathways.

Students with efficiently wired brains have the ability to learn interesting facts in an easy manner and they perform better in a general knowledge test than the other students. They often search for popular online sources to look for general knowledge facts. For example, if they want to search for ‘what is duckduckgo,’ they easily get an answer on the web. Plenty of online sources provide information related to interesting facts to help people increase their general knowledge.

The results of the study showed that both age and sex were linked to higher general knowledge but the team of researchers found that the variation was due to the structure of the brain (the global efficiency of the structural network or NETstruc). According to the biopsychologist Erhan Genc, from Ruhr University Bochum, the more efficient networking of the brain helps to better integration of pieces of information which eventually contributes to better results in a general knowledge test.

Getting to the Root of It! Lebanese Cosmetic Dentist Dr. Mohammad Waizani Explains Root Canal Treatments

Did you know that more than 15 million teeth are treated and saved every year? One of the most common treatments received are root canal treatments. At Dr. Mohammad Waizani’s clinic in Beirut, he specializes in making sure anyone who comes in with a root canal, leaves with a bright smile! 

A root canal treatment is a dental procedure in which the soft center of the tooth called a ‘pulp’ is removed. The pulp is made out of blood vessels, connective tissues, and nerves. In these cases, the pulp is infected after being exposed to bacteria that causes a lot of pain. The crown of the tooth is usually still intact despite the pulp being dead. 

Root canals can be caused by several reasons such as a chip or cracked tooth, deep decay due to cavities that are left untreated, an injury to the tooth, and multiple procedures on the same tooth. 

Some of the signs of root canal infections include the following:

  • Constant toothache 
  • Heat sensation and swelling of gums
  • Sensitivity to heat and cold 
  • Swollen jaw
  • Discoloration of teeth
  • Pain with applied pressure 

Dr. Waizani explains how this surgical procedure works to remove the pulp and ensure the tooth doesn’t get infected. He starts by applying anesthetics to the gum and around the infected tooth. Next, the pulp is removed through a small opening at the top of the tooth. After the procedure is done, his patients’ recovery includes antibiotics to ensure that that infection does not flare up post-procedure. This is followed by a temporary filling. 

If you are experiencing any of the symptoms mentioned, there is no need to panic. Contact Dr. Waizani to schedule your appointment!
