Brain cells

What is the brain made of?


The brain consists of several types of cells, each with distinct characteristics. Neurons and glial cells are the most common brain cells. Neurons send and receive chemical and electrical signals to transmit information between neurons, tissues, and muscles in the body. A neuron consists of a body, and its branching dendrites have a relationship Transmitting and receiving signals from other neurons, and the axon that transmits signals to surrounding neurons.

Glial cells hold neurons in place, and there are several types of glial cells, including; The oligodendrocytes that isolate the axon of the neuron, forming the myelin sheath, the microglia, and the immune cells of the central nervous system, which clean the brain of damaged and dead cells due to disease or infection, and astrocytes that have a role in supporting the neurons, and this article will talk about 8 Things that may kill brain cells and limit his mental ability


8 things that can kill brain cells


And limiting his mental ability Mental ability is defined as a person’s ability to make his own decisions, and many things may affect a person’s mental ability from him; Brain injury or stroke, learning disability and mental illness, and in the following 8 things that may kill brain cells and limit their mental ability:


Not getting enough sleep


Not getting enough sleep prevents nerve cells from doing their job properly, making it difficult to focus and think during the day. When they performed some specific tasks, their brain activities were measured, and the researchers noticed that lack of sleep had a greater impact on some areas of the brain than others.

 UCSD Professor of Neurosurgery Dr. Isaac Farid: This phenomenon indicated that specific regions of the patients' brains were sleeping, causing mental lapses, while the rest of the brain remained awake and functioning as normal.


Spend a long time alone


In one of the studies conducted on mice that were placed alone, where signs of brain damage were observed, and after a long period of being alone, there were smaller neurons in certain areas of the brains of isolated mice, as well as other changes in the brain. The same damage was done to a lonely person

Neuroscientist Hoda Akil: There is no doubt that this changes the basic structure of the brain.


Eating a lot of fast food


There is a relationship between a poor diet and dementia due to high cholesterol and blood pressure that affects the blood flow to the brain, and research has shown that eating a lot of fast food may raise the level of insulin in people, and exposure of the brain to a lot of insulin may prevent it from responding correctly to insulin, and affects This negatively affects memory and reduces the brain's ability to think

Research has shown that eating a lot of fast food may raise the level of insulin in people, and exposure of the brain to too much insulin may prevent it from responding properly to insulin.


Increase the volume to the maximum when using earphones


There are 8 things that may kill brain cells and limit its mental ability, one of which is raising the volume to the maximum when using headphones, as research has shown that raising the volume to the maximum when using headphones has an effect similar to multiple sclerosis on the nerves and can lead to hearing loss, as it was found When the noise level is more than 110 decibels, the nerve fibers that transmit signals from the ear to the brain lose the myelin insulating material, thus stopping the electrical signals of the nerves.


Not moving enough


It is necessary to know 8 things that may kill brain cells and limit its mental ability, including insufficient movement. There is a relationship between learning and movement. Many evidence from clinical data sources, anatomical studies and imaging show the role of moderate exercises in enhancing cognitive processes, as it has a role in increasing cognitive processes. Brain cells, since the area of ​​the brain that processes learning is the same area of ​​the brain that processes movement.


Smoking


Cognitive ability naturally declines with age, and one study showed that cognitive ability declines faster in middle-aged male smokers compared to non-smokers, and in another study that compared non-smokers and smokers and showed that smokers are 30% more likely to develop dementia.Smokers are 30% more likely to develop dementia.


Eat a lot


One study showed that eating too many calories over time can increase the likelihood of mild cognitive decline (MCI) or memory loss. The study showed that when a person has an increased risk of cognitive impairment with age, eating a lot of calories is associated with an increased risk of cognitive impairment.


Stay in the dark for a long time


Staying in the dark for a long time can disrupt the sleep cycle in individuals, as the regulation of the sleep cycle depends on the nucleus of the brain above the junction and the hormone melatonin, and melatonin levels decrease when exposed to daylight and thus helps the individual to feel awake, and this disturbance in the wake-sleep cycle can make a person feel It has been linked to an increased risk of cancer and other problems.
