Making sense of scents: 3D videos reveal how the nose detects odor combinations

Every moment of the day we are surrounded by smells. Odors can bring back memories, or quickly warn us that food has gone bad. But how does our brain identify so many different odors? And how easily can we untangle[…]

Sweet as: The science of how diet can change the way sugar tastes

Researchers have discovered the basic science of how sweet taste perception is fine-tuned in response to different diets. While it has long been known that food can taste different based on previous experience, until now we didn't know the molecular[…]

First in-human study of drug targeting brain inflammation supports further development

MW189 blocks abnormal inflammation in the brain that is known to contribute to injury- and disease-induced neurologic impairments in a number of acute and chronic brain disorders. This study examined MW189 in healthy adult volunteers.

Correlation between MBI and Alzheimer's

New research has found that the presence and severity of mild behavioral impairment (MBI) in cognitively healthy individuals is strongly associated with the presence of amyloid plaques deposits in the brain, a hallmark of Alzheimer's disease.

Brain discovery suggests source of lifelong behavioral issues

Improper removal of faulty brain cells during neurodevelopment may cause lifelong behavioral issues, new research suggests. The finding also could have important implications for a wide range of neurodegenerative diseases, such as Alzheimer's and Parkinson's.

Promising advance in depression research

Despite their effectiveness, only 40% of patients respond to the first antidepressant they try. A recent article strongly suggests that a particular protein, GPR56, is involved in the biology of depression and the effect of antidepressants. The research team believes[…]

Repairing stroke-damaged rat brains

Researchers have succeeded in restoring mobility and sensation of touch in stroke-afflicted rats by reprogramming human skin cells to become nerve cells, which were then transplanted into the rats' brains.

It's now or never: Visual events have 100 milliseconds to hit brain target or go unnoticed

Researchers have defined a crucial window of time that mice need to key in on visual events.

Genes sow seeds of neuropsychiatric conditions before birth, in early childhood

From early prenatal development through childhood, the prefrontal cortex of the human brain undergoes an avalanche of developmental activity. In some cases, it also contains seeds of neuropsychiatric conditions, according to a new genetic analysis.

How serotonin balances communication within the brain

Our brain is steadily engaged in soliloquies. These internal communications are usually also bombarded with external sensory events. Hence, the impact of the two neuronal processes need to be permanently fine-tuned to avoid their imbalance. A team of scientists has[…]

Babies retain even detailed events during a nap

While sleeping the brain goes through previously experienced things, consolidates new memory contents and summarizes similar experiences into more general knowledge. This also applies to babies. However, they can more than just generalize what they have learned. A recent study[…]

New practices improve stroke care

A new method of evaluating and prioritizing treatment for patients with suspected acute stroke, which has been used by the Stockholm health authority since 2017, has led to faster health interventions and better patient care, shows a new study.

Compound in fruit peels halts damage and spurs neuronal repair in multiple sclerosis

Ursolic acid, abundant in fruit peels and some herbs, both prevents and repairs neurons in animal models of multiple sclerosis.

Alzheimer's trial screening data links high amyloid levels with early stage disease

A new study supports the hypothesis that higher levels of amyloid protein in the brain represent an early stage of Alzheimer's disease. Screening data for the study show that amyloid burden in clinically normal older adults is associated with a[…]

Neuroscientists find memory cells that help us interpret new situations

Neuroscientists have identified populations of cells that encode distinctive segments of an overall experience. These chunks of memory are encoded separately from the neural code that stores detailed memories of a specific experience.

Scientists reveal brain tumors impact normally helpful cells

Unprovoked recurrent seizures are a serious problem affecting most patients who suffer from glioma, a primary brain tumor composed of malignant glial cells. Researchers tested the hypothesis that glioma-induces processes that renders a type of brain cells dysfunctional, perpetuating the[…]

Stress thwarts our ability to plan ahead by disrupting how we use memory

Pairing brain scans with virtual-navigation tasks, researchers found that people make less efficient and effective plans when stressed.
