Discrimination during pregnancy may alter circuits in infants’ brains

Racial discrimination and bias are painful realities and increasingly recognized as detrimental to the health of adults and children. These stressful experiences also appear to be transmitted from mother to child during pregnancy, altering the strength…

Why do some older adults show declines in their spatial memory?

A study has investigated the possible scenarios that could lead to waning memory in some older people.

Serotonin loss may contribute to cognitive decline in the early stages of Alzheimer’s disease

Comparing PET scans of more than 90 adults with and without mild cognitive impairment (MCI), researchers say relatively lower levels of the so-called ‘happiness’ chemical, serotonin, in parts of the brain of those with MCI may play a role in memory pro…

Protein found in brain linked to frontotemporal dementia

An international team of researchers has identified a protein found in the brains of people with frontotemporal dementia (FTD), discovering a new target for potential treatments for the disease.

Repeated blast exposures may harm the brain health of military personnel

The brains of special warfare community personnel repeatedly exposed to blasts show increased inflammation and structural changes compared with a control group, potentially increasing the risk of long-term, brain-related disease, according to a new study.

New protein linked to early-onset dementia identified

Scientists have identified abnormal aggregates of a protein called TAF15 in the brains of individuals with early-onset dementia, known as frontotemporal dementia, where the cause was not previously known.

Unlocking the secrets of the brain’s dopaminergic system

A new organoid model of the dopaminergic system sheds lights on its intricate functionality and potential implications for Parkinson’s disease. The model replicates the dopaminergic system’s structure, connectivity, and functionality.

Glial tone of aggression

While anger and aggression are instinctive behaviors found across many species, leaving these emotions unchecked can lead to conflict and violence. In a recent study, researchers demonstrated that neuronal-glial interactions in the cerebellum determine…

Brains of newborns aren’t underdeveloped compared to other primates

Contrary to current understanding, the brains of human newborns aren’t significantly less developed compared to other primate species, but appear so because so much brain development happens after birth, finds a new study.

New study maps ketamine’s effects on brain

A mouse study found that the drug ketamine can alter the brain’s dopamine system, boosting the case for more targeted medical use.
