This article examines cognitive functioning, how the brain works, typical function versus cognitive decline, mild impairment, dementia, and ways to improve cognitive function.

WASHINGTON :Neuroscientists have produced the largest wiring diagram and functional map of a mammalian brain to date using tissue from a part of a mouse's cerebral cortex involved in vision, an ...

It’s impossible to overstate the importance of our brain. The organ, housed inside the skull and protected by a bony covering called the cranium, controls thought, memory, emotion, vision, and ...

Brain dynamics and cognition share genetic roots. Criticality may guide future brain health research. A recent study published on June 24 in PNAS presents strong evidence that brain criticality—the de ...

Hormone cycles shape the structure and function of key memory regions in the brain Date: May 13, 2025 Source: University of California - Santa Barbara ...

Brain-wide association studies, which use magnetic resonance imaging to identify relationships between brain structure or function and human behavior or health, have faced criticism for producing ...

Their work also demonstrates the intimate role of brain 5-HT4 receptors in cognitive function. This confirms recent work from Oxford showing that the 5-HT4 receptor stimulant, prucalopride – a ...

As criticality gradually deteriorates, the brain works harder to achieve the same cognitive outcomes, Hengen said. "It's like an engine that still runs but requires more fuel and generates more heat.
