What sponges can tell us about the evolution of the brain

Added: 08.11.2021 23:22 | 196 views | 0 comments

What can sponges tell us about the evolution of the brain? Sponges have the genes involved in neuronal function in higher animals. But if sponges don't have brains, what is the role of these? Scientists imaged the sponge digestive chamber to find out.

Restoring normal sleep reduces amyloid-beta accumulation in mouse model of Alzheimer’s disease

Added: 08.11.2021 23:22 | 170 views | 0 comments

A team has discovered that, in an animal model of Alzheimer's disease, restoring normal sleep by returning to normal the activity of the thalamic reticular nucleus (TRN), a brain region involved in maintaining stable sleep, reduced the accumulation of A-beta plaques in the brain.

Brain reveals the risk for developing obesity

Added: 08.11.2021 23:22 | 193 views | 0 comments

Obesity risk factors of family background are associated with changes in the brain function, finds a new study. The results show that the function of neural networks regulating satiety and appetite is altered already before a person develops obesity.

When building rapport, sometimes less is more

Added: 08.11.2021 23:22 | 189 views | 0 comments

Sometimes less is more, at least when it comes to building rapport during interviews. That's according to new research which reveals that verbal interviewing techniques have a greater impact than nonverbal techniques -- and combining the two had a detrimental effect.

Our brains may think two steps ahead when trying to sway others

Added: 08.11.2021 23:22 | 197 views | 0 comments

In an effort to understand how a sense of control over others may influence the brain's decision-making processes, researchers have tested the ability of healthy human subjects to play a bargaining game. For the first time, they found that people used "forward thinking" when trying to sway others. Forward thinking happened regardless of whether the subjects could actually influence others and appeared to be driven by neural activity in a well-known decision-making center of the brain.

Insomnia may be a risk factor for highly fatal brain aneurysm rupture

Added: 08.11.2021 23:22 | 187 views | 0 comments

Researchers identified insomnia as a potential risk factor for brain aneurysm, also called an intracranial aneurysm, and a type of stroke called an aneurysmal subarachnoid hemorrhage. Smoking and high blood pressure, which are identified stroke risk factors, were also associated with increased risk for brain aneurysm. According to researchers, the finding that insomnia may be a potential risk factor for intracranial aneurysm is new and calls for additional research.

Lithium imaging method could shine new light on bipolar disorder, treatment

Added: 08.11.2021 23:22 | 177 views | 0 comments

Since 1949, lithium has been a mainstay for treating bipolar disorder (BD), a mental health condition marked by extreme mood swings. But scientists still don't have a clear understanding of how the drug works, or why some patients respond better than others. Now, researchers have developed a method for imaging lithium in living cells, allowing them to discover that neurons from BD patients accumulate higher levels of lithium than healthy controls.

Giant leap taken in fighting antibiotic resistance

Added: 08.11.2021 23:22 | 169 views | 0 comments

Scientists may have made a giant leap in fighting the biggest threat to human health by using supercomputing to keep pace with the impressive ability of diseases to evolve. A new study has tackled the problem of antibiotic resistance by redesigning existing antibiotics to overcome bacterial resistance mechanisms.

Too assesses how well people read kids’ emotions

Added: 08.11.2021 23:22 | 179 views | 0 comments

Psychology researchers have developed and validated a new tool for assessing how accurate people are at recognizing emotion in elementary school-aged children. The technique will facilitate research on understanding emotions of children -- and highlights that adults are often wrong when assessing the emotions of children.

Recognizing familiar faces relies on a neural code shared across brains

Added: 08.11.2021 23:22 | 174 views | 0 comments

The ability to recognize familiar faces is fundamental to social interaction. This process provides visual information and activates social and personal knowledge about a person who is familiar. But how the brain processes this information across participants has long been a question. Distinct information about familiar faces is encoded in a neural code that is shared across brains, according to a new study.

New test to diagnose aggressive childhood brain tumors

Added: 08.11.2021 23:22 | 193 views | 0 comments

Researchers have developed a new test to more easily diagnose medulloblastoma, the most common malignant childhood brain tumor. The test -- which can distinguish between extremely high-risk medulloblastoma cases that need radiation therapy from those that are lower-risk and do not need radiation -- could help pave the way for personalized treatment options for children suffering from the disease. It relies on an antibody-based technique called immunohistochemistry which is widely available in clinical laboratories around the world.

Scientists have discovered a new type of nerve cell, or neuron, in the retina. In the central nervous system a complex circuitry of neurons communicate with each other to relay sensory and motor information; so-called interneurons serve as intermediaries in the chain of communication.

Men experience more emotional pain during breakups

The stereotype of men being less emotionally invested in relationships than women may not be accurate, say psychologists. A new study of online relationship support finds that men tend to experience emotional pain more than women when their relationship takes a turn for the worse.
