New research in mice raises the prospects for development of post-concussion therapies that could ward off cognitive decline and depression, two common conditions among people who have experienced a moderate traumatic brain injury.

A new study has found that older adults are no more likely to fall for fake news than younger adults, with age-related susceptibility to deceptive news evident only among those categorized as the 'oldest old.'

Atrial fibrillation, the most common cardiac rhythm abnormality, has been linked to one-third of ischemic strokes, the most common type of stroke. But atrial fibrillation is underdiagnosed, partly because many patients are asymptomatic.

A group of rare diseases called ciliopathies -- polycystic kidney disease notable among them -- emerge from defects in cilia. These are the tiny hairlike structures on the surface of almost every cell type. Scientists experimentally 'knocked out,' or genetically deleted, the cilia in a population of otherwise normal human pluripotent stem cells. Subsequently, human tissues and mini-organ structures (organoids) derived from these cilia-free stem cells manifested ciliopathy-like symptoms, such those seen in polycystic kidney disease or in certain problems in brain development.

Researchers have uncovered a new way to help identify babies and fetuses at high-risk of developing brain bleeds, paving the way for better early intervention.

Researchers who previously discovered channels in the skull have found that cerebrospinal fluid can exit the brain through these channels to reach the skull's bone marrow, which can detect and respond to infection or injury. Tapping into this process may help investigators study and treat inflammation-related brain conditions.

A new study suggests that reducing daily sedentary time can have a positive effect on the risk factors of lifestyle diseases in only three months. Spending just one hour less sitting daily and increasing light physical activity can help in the prevention of these diseases.

Just one single neuron can realize deep learning algorithms, which previously required an artificial complex network consisting of thousands of connected neurons. This discovery is expected to have important implications on future AI hardware.

Our understanding of the prehistory of the Finnish language is becoming clearer: Shifts in climate and periods of drought may have been the original reasons for which the community, which originated in western Siberia, spread first from east to west and later from south to north.

Researchers have applied a chemogenetic tool in macaque monkeys and suppressed the subthalamic nucleus, a part of the basal ganglia circuitry. The chemogenetic suppression induced unstable movements. In the output nucleus of the basal ganglia, the internal pallidum, neurons showed no firing rate change, but their spike train became variable. The subthalamic nucleus may stabilize neural activity in the basal ganglia for smooth movements.
