A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain’s neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. University of Basel researchers report in the journal Nature how neuronal networks in the mouse brain are fine-tuned.
One of the characteristics of depression is a tendency to perceive sensory stimuli and everyday situations in an excessively negative way. But the mechanisms underpinning this “negativity bias,” which can fuel the development of depressive symptoms, had previously remained largely unknown.
A new study sheds light on how highly creative individuals, such as visual artists and scientists, may have brains that function differently compared to others. The research, published in Psychology of Aesthetics, Creativity, and the Arts, reveals that people who exhibit exceptional creativity—referred to as “Big C” creative individuals—demonstrate…
Different brain regions are connected by—and interact through—networks of neurons. But the extent to which neuronal wiring drives shared function between these different regions is not well understood. Is this structure-function relationship the same throughout the brain? The same across functions?

Scientists have identified a natural compound that halts the process involved in the progression of certain forms of cancer and demyelinating conditions—those that damage the sheath, known as myelin, that surrounds neurons—such as multiple sclerosis.
New research reveals that prolonged mental load weakens brain connectivity, but compensatory mechanisms keep cognitive performance steady.
Summary: A recent study shows that prolonged mental exertion weakens connectivity between the brain’s frontal and parietal lobes, impacting cognitive efficiency. However, the brain has built-in compensatory mechanisms that adjust neural connections to preserve function under fatigue.
Researchers observed this in participants completing memory tasks of varying difficulty; while fatigue slowed performance on simple tasks, complex tasks triggered compensatory adjustments. Findings suggest that these mechanisms allow the brain to optimize resources based on task complexity.

UC Santa Barbara researchers discovered that single, vigorous exercise sessions, especially under 30 minutes, improve cognitive functions like memory and executive function. Future studies will explore whether combining physical activity with cognitive tasks yields even greater benefits.
Years of research on exercise have long supported the idea that consistent workouts over time lead to both physical and cognitive benefits. But what about short, intense bursts of exercise? A team of scientists at UC Santa Barbara has taken a closer look.
Their study was recently published in the journal Communications Psychology.
New research underscores the role of the immune system in depression, linking inflammation to poor response to standard antidepressants and highlighting the importance of personalized medicine in addressing different biological patterns in depressed individuals.
A collaborative study between researchers from the UK and Italy has uncovered new insights into the biological mechanisms of major depressive disorder (MDD), with a particular focus on the role of the immune system.
The researchers examined “gene expression,” which refers to the process by which the instructions in our genes are activated, influencing bodily functions.
