The Dhaka Times Desk How many things are in people's heads, it is still a mystery! Hundreds of scientists have teamed up to find the path to that labyrinth. This time they have created a 'map' of the human brain.
Experts claim that such a detailed 'atlas' has never been created before. They identified more than 3,000 cell types. Some of these cells were previously unknown. 21 research papers were published in the journals 'Science', 'Science Advances' and 'Science Translational Medicine'. The most complex organ in the human body is the brain. Much of it is unknown.
Anthony Hannan, a neuroscientist at the Flor Institute of Neuroscience and Mental Health in Melbourne, Australia, said, "This research is very important. Even earlier, scientists created brain maps through 'Magnetic Resonance Imaging' method. But it didn't have that much detailed information either. This is the first complete brain atlas created at the cellular level. It even captures the molecular reactions in brain cells.
This research is a part of the US National Institutes of Health research. More advanced neurotechnology is also used in it. Hundreds of scientists from different parts of the world are involved in this research. The main goal of this project is to create a catalog of brain cells. Not only humans, but scientists are also trying to gather information about brain cells and their types from chimpanzees to mice, different animals. In this way, scientists believe that it will be possible to know about various brain diseases and their causes.
Neuroscientist Kimberly Siletti and her team at the University Medical Center Utrecht in the Netherlands have played a significant role in brain mapping. The scientists sequenced the RNA of more than 300,000 cells from 106 locations in the brain. The test was done by collecting testicles from 3 donated male bodies.
The motor cortex of a female cadaver was also used. Kimberly discovered 461 cell types. There are 3,000 subtypes of those cells. "I was surprised to see so many cells," he said.
Another scientist associated with this study, Stan Linerson, said, "The brainstem connects the brain and the spinal cord. This part contains most types of neurons or nerve cells. What we've seen in this study is how complex the brainstem is.''
Bing Ren, a molecular biologist at the University of California, said the study identified brain diseases as well as the exceptional gene manipulation behind them. In this way, the brain disorder will be known well. This researcher said that if the disease is understood, its cure will also be found.

How to prevent dengue
Dengue is a mosquito-borne viral fever. This fever is different from other viral or bacterial fevers. However, this fever is not contagious in any way. This viral fever can occur alone or in combination with other viruses (chikungunya, yellow fever, Burma forest, flu, respiratory syncytial) and bacteria (pneumococcus).
Dengue fever is divided into two categories depending on the severity of symptoms and fever.
1. Common dengue fever
2. Dengue fever with bleeding.
In the case of common dengue fever, the following symptoms are mainly seen-
1. Sudden high fever lasting 2 to 7 days.
2. Severe headache.
3. Pain behind the eyes.
4. Along with the fever, red rash appears all over the body.
5. Severe pain in whole body as well as back pain.
6. Nausea or vomiting.
7. A rash or red bumps on the skin.
In case of dengue fever with bleeding:
1. Bleeding from nose, mouth or vomiting with high fever within 2 to 48 hours.
2. Fluid accumulation in chest or abdomen along with fever.
If any of these symptoms appear, seek medical attention immediately.
On the other hand
Wait at home for the first 3 days of fever. On the other hand, sponge the whole body with water every now and then. This will reduce the level of fever. Drink enough water and rest. After that, if the fever does not decrease or if it continues to increase after some time, consult a doctor immediately.
Things to do to prevent Dengue:
1. Try to keep the surroundings of the house as clean as possible.
2. If there are flower tubs or broken plastic bottles, can shells, tires or polythene inside the house, clean them quickly and drain the accumulated water from the flower tubs.
3. Spray or fog at least 3 times a week to kill mosquitoes.
4. You can keep mosquito repellent cream with you while going out.
5. After evening, younger and older members of the household should use mosquito nets.
6. Clean up any accumulated rain water, as this is the time when Aedes mosquitoes lay their eggs.
7. On the other hand, you can use mats along with mosquito nets to avoid mosquito infestation.
8. Since Aedes mosquitoes bite during the day, it is important to avoid sleeping with mosquito nets while sleeping during the day. Source: https://dmpnews.org
