Immune cells ATTACK the aging brain and release a substance that hinders new nerve cell production, report scientists
One of the defining features of the brain that sets it apart from all other organs of the human body (except muscles) is that it is made up of cells that cannot regenerate. The nerve cells in the brain called neurons are terminally differentiated, meaning that, unlike skin cells or blood cells, they cannot reproduce. So […]

Does our brain have an internal hunger switch? Researchers identify neurons that could “turn off” appetite
Eating is a basic activity performed by all living organisms. Yet there is still much to learn about it, especially how and why eating becomes disordered. The National Eating Disorder Association reports that up to 30 million people in the U.S. suffer from an eating disorder, such as overeating, undereating, anorexia or bulimia. But despite eating being more commonly […]

Optogenetics and your brain: Researchers study the therapeutic potential of light
Can light restore vision to blind people and help treat paralysis in patients with Parkinson’s disease? German researchers have recently examined the possibility of stimulating light-sensitive proteins to achieve therapeutic effects on various health conditions. Optogenetics is a technique that manages processes in the brain through light-based stimulation. It achieves its effects through light-controlled proteins […]

Which brain cells are active during deep sleep – and how do they affect memory formation?
There are neurons in the brain that activate during deep sleep to create memories. A new animal study showed that these brain cells might be the same as the ones responsible for investigating new objects. The experiment tracked the activity of single cells deep in the brains of both male and female mice as they […]

Flashing lights and pink noise could be the key to preventing Alzheimer’s
Researchers believe they have found a potential treatment for Alzheimer’s disease. Animal tests show that exposing mice to light flashes and sound pulses at the frequency of 40 hertz can reverse some of the symptoms of the neurodegenerative disease. Alzheimer’s disease continues to defy any attempt at treating it. Several pharmaceutical drugs help regulate a few […]

A single workout can activate neurons that boost metabolism for days
A common concern that a lot of people have after an intense workout is whether they will be able to move for the next few days. If you belong to this group and think that taking a short break from your routine could destroy everything you worked hard for – don’t be. A study from the University of Texas […]

Controversial study claims human memory cells do not grow throughout life, but stop regenerating before adulthood
Until the early 1980s, scientists accepted the findings of Santiago Ramón y Cajal – the father of modern neuroscience – that adult brains do not experience neurogenesis, the process in which the brain renews itself by producing new neurons. Experts started questioning this belief in the past few decades, however, after research confirmed that other […]

Scientists transfer one snail’s memory onto another, potentially unlocking secrets of human memory transfer
American researchers reported that they implanted the memory of a sea snail into another individual snail. The technique might very well be applied to humans in the future, allowing memories to be transferred, altered, or even erased. The researchers developed the technique with Aplysia snails, which are also called sea snails, sea hares, and sea […]

Children with autism appear to lose neurons related to social and emotional behavior as they age, study finds
Studies have shown that developing children gain more neurons in their brain’s amygdala – the region that regulates emotions and controls social behavior – as they grow older. However, researchers at the UC Davis MIND Institute found that this phenomenon does not happen in children with autism spectrum disorder (ASD), and instead appear to lose the neurons […]

Is treatment making it worse? DNA damage to brain cells can be caused by nanoparticles from medical treatments
Nanoparticles are seeing use in an increasingly large number of medical procedures and treatment methods. However, Irish researchers are concerned that their use might be doing far more harm than good. They report that metal nanoparticles could be damaging the DNA of developing brain cells like neurons, according to an article by NanoWerk. According to […]
