National regulatory authorities have approved six vaccines for public use:

2 RNA vaccines (the Pfizer-BioNTech COVID-19 vaccine

what loneliness looks like in the brain

 


 what loneliness looks like in the brain


A new study shows a signature in the brains of lonely people that make them distinct in fundamental ways, based on variations in the volume of different brain regions as well as based on how those regions communicate with one another across brain networks.


Loneliness is an unpleasant emotional response to perceived isolation. 


Loneliness is increasingly being recognized as a major health problem, and previous studies have shown older people who experience loneliness have a higher risk of cognitive decline and dementia. Understanding how loneliness manifests itself in the brain could be key to preventing neurological disease and developing better treatments.


A team of researchers examined the MRI data, genetics and psychological self-assessments of approximately 40,000 middle-aged and older adults . They compared the MRI data of participants who reported often feeling lonely with those who did not.


The researchers found many differences in the brains of lonely people. 

These brain manifestations were centred on default network: a set of brain regions involved in inner thoughts such as reminiscing, future planning, imagining and thinking about others.


Researchers found that the default networks of lonely people were more strongly wired together and surprisingly, their grey matter volume in regions of the default network was greater. 


Loneliness also cause differences in the fornix: a bundle of nerve fibres that carries signals from the hippocampus to the default network. In lonely people, the structure of this fibre tract was better preserved.


We use the default network when remembering the past, envisioning the future or thinking about a hypothetical present. The fact the structure and function of this network is positively associated with loneliness maybe because lonely people are more likely to use imagination, memories of the past or hopes for the future to overcome their social isolation.


So this heightened focus on self-reflection, and possibly imagined social experiences, would naturally engage the memory-based functions of the default network.

Dental Emergencies

 


Dental Emergencies

Any dental problem that needs immediate treatment to stop bleeding, alleviate severe pain, or save a tooth is considered an emergency. This consideration also applies to severe infections that can be life-threatening.

  • Uncontrolled bleeding
  • severe uncontrolled pain
  • cellulitis or a diffuse tissue swelling
  • Infection with intra oral or extra oral swelling that compromises airway
  • Trauma of face or facial bone
  • Severe trismus
  • Persistent non healing ulcer

Here are some simple precautions you can take to avoid accident and injury to the teeth:   
Wear a mouthguard when participating in sports or recreational activities.

Avoid chewing ice, popcorn kernels and hard candy, all of which can crack a tooth.

Use scissors, and not  your teeth, to cut things.

Which is the best tooth brush?


Which Toothbrush is best?

1. Plastic manual: plastic handle with fixed head.
           or
2. Bamboo manual: bamboo handle with fixed head.
            or
3. Plastic manual replaceable head: reusable plastic handle (made from a bio-plastic) with replaceable heads.
            or
4. Electric: handle and charging unit, with replaceable heads.

There are billions of toothbrushes used and discarded every year. Research shows that electric toothbrushes are actually harmful for the planet and to the people involved in the manufacturing process and distribution.

The electric toothbrush, the standard plastic brush, the plastic brush with replaceable head, and the bamboo brush were used. The team found that the electric toothbrush was comparatively harmful for planetary health.

Even though bamboo is biodegradable the most environmentally sustainable toothbrush was not bamboo, as could perhaps be popularly believed, but a hypothetical continually recycled plastic toothbrush.

A plastic manual replaceable head toothbrush and bamboo manual toothbrush perform better than traditional plastic manual and electric toothbrushes in every environmental impact.

The ideal toothbrush is one which uses plastic which is recycled in a continuous process. Plastic brushes which can be recycled don't take up a lot of land, and they don't need lots of water to grow. The important thing here is to keep the plastic in the recycling chain.
