feelings of others

A study found that people who were exposed to emotional images reacted according to the reactions of others and judged harshly those who did not react like everyone else

The cause of aging: cumulative damage from factors such as radiation and smoking causes low expression of long genes

  • No comments
Dutch researchers found that this process happens all the time and damages all genes, but the longer the genes, the more likely they are to be damaged because they have more sites. Especially the great damage is to nerve cells due to their inability to regenerate

How - and where - does a disease begin?

Researchers discovered which genes are required for each stage of cell differentiation into neural stem cells and neurons, i.e. for brain development, and which of them are involved in diseases of the nervous system

This is how the bone marrow reacts to injuries and infections

  • No comments
Dr. Kathryn Vandorna from the Faculty of Biomedical Engineering at the Technion developed a new method that allows the monitoring of the formation of immune blood cells in the bone marrow. For this purpose, she used tiny magnetic particles of iron oxide, which she followed with various imaging methods, including MRI of the living creature

A new study at the University of Haifa found for the first time a connection between Parkinson's disease and the extracellular matrix in the brain

  • No comments
Extracellular matrix is ​​the part of the tissue that surrounds the cells and provides them with structural support. Beyond the structural function of the matrix, it is used for a variety of roles, such as separating tissues from one another and controlling intercellular communication, hence its role in this disease
A man implanted with a brain chip and started walking. The image was created by the artificial intelligence software DALEE and is presented as an illustration only and is not a scientific image.

First brain chip that treats epilepsy and OCD at the same time

Implanting a chip in the brain as recently done by Elon Musk's company Neurolink can, if done correctly, save patients with severe brain diseases, and that the patients no longer respond to drug treatment

Reading while walking with smart glasses is more difficult compared to reading from a mobile phone

  • No comments
Our research shows that when walking, the smart glasses reduce the ability to perform both walking and reading texts, and this can also have an impact on the safety of the users," said Dr. Tal Krasovsky from the University of Haifa, the author of the study
Reading thoughts before they become words. The figure was prepared using DALEE software after reading the article.

mind reading? Researchers have developed a method that will allow us to know what we are going to say before we speak

  • No comments
Individual neurons could recognize, for example, when we are about to touch our tongue to our palate to say the letter D * This will enable the development of prostheses for those suffering from speech problems

Researchers are examining whether aerobic physical activity, which increases the level of oxytocin, the hormone of love and connection in the body, may improve the social functioning of those suffering from schizophrenia
The pituitary gland of the zebrafish. The variety of cell types are marked in different colors: in purple - phytocytes, in red and green - two types of hormone-producing cells

Where does the fish secrete from: back to the origins of the pituitary gland

Weizmann Institute scientists are challenging a 200-year-old doctrine about the formation of the gland from the secretion of hormones. Their findings may lead to new approaches in the treatment of various medical problems

A mechanism has been discovered that causes sleep apnea in sick children

  • No comments
One of the diseases resulting from such mutations in the PHOX2B gene is the disease CCHS. This is a rare and life-threatening syndrome in which babies, children and adults stop breathing as soon as they fall asleep. The patients must be connected to ventilators in order not to die in their sleep

Elon Musk's Neuralnik Implanted a Chip in a Man's Brain: Medical and Ethical Implications

  • No comments
The chip should provide a variety of health and scientific benefits, including the ability to measure brain activity and give people with physical or mental disabilities new abilities. However, Musk's company and Musk in general have a problematic history

The mechanism that dramatically links anxiety and testosterone has been discovered

  • One response
Krim suggests a close link between low levels of testosterone and anxiety disorder, although the exact nature of this relationship remains unclear. Clinical evidence suggests the potential of testosterone in alleviating anxiety and depression, especially in men with low testosterone.

When and why are we ready to give up money?

Researchers have found that fulfilling a stereotype leads to a reward response in the brain and that people are even willing to give up money for it

In the tears you cry: smelling women's tears reduces aggression in men

Scientists at the Weizmann Institute of Science discovered that tears activate human olfactory receptors, even though they are odorless, affecting the brain activity associated with aggression - and leading to more peaceful and less vengeful behavior
On the right: the brain's response to speech that is listened to (above) and speech that is tried to be ignored. It can be seen that the brain's response is stronger to attentive speech and that this response involves more brain areas, with an emphasis on hearing and language areas.

The biology of listening

The human attention system can be dynamic, efficiently jumping between stimuli and taking in a lot of information, so it is not static as is commonly thought.
Brain during stress and without it. SN - the saliency network: reacts to significant events for a person, and when stressed expands in the cerebral cortex at the expense of the executive functions network ECN - the executive functions network: involved in attention, working memory, emotional regulation and social functioning and studies DMN - the default network: a system of brain areas that is mainly active in situations Rest in which the person is awake. Changes significantly after exposure to trauma and depression and anxiety

on anxiety and relaxation

Negative events in childhood and sleep problems make it difficult to recover from an acute stress disorder and thus increase the risk of a mental disorder
