Memory rejuvenation restored recall in mice
An EPFL Neuron study found that brief OSK gene activation in memory-trace neurons improved recall in aged and Alzheimer's-model mice. The result suggests some memory decline may reflect aging neurons rather than erased memories, but it does not show human memory restoration.
Introspection provides our most direct contact with physical reality
Some authors argue introspection is our least sensory-mediated access to experience. But introspective reports are not direct neural measurement, and they can be unreliable.
Musical training is linked to better body orientation without vision
In a small lab study, musicians showed less disorientation on a blindfolded stepping task compared to non-musicians.
Flow state explains how deep focus boosts happiness and performance
Flow state is a deep immersion that boosts performance and mood. Learn how to achieve flow state using psychology and neuroscience to get in the zone.
A fully synthetic scaffold grows brain-like tissue without animal coatings
UC Riverside researchers report a fully synthetic scaffold that grows functional brain-like tissue without animal-derived materials or added biological coatings.
videoHigh brain activity and micro-awakenings explain why some people remember dreams better
High brain activity in the temporo-parietal junction causes micro-awakenings that let some people remember dreams, while deep sleepers forget them.
Long COVID brain fog linked to a change in brain cell receptors
Long COVID brain fog linked to higher AMPA receptors on PET scans; new study points to a biological marker and possible AMPAR-targeted treatments.
Spinal cord ejaculation study reshapes sex research
A 2025 mouse study found that spinal cord neurons help shape sexual arousal, pacing, and ejaculation. It does not show that the spinal cord replaces the brain or that the same mechanism is proven in humans.
Artificial sweeteners may speed cognitive decline
A large observational study linked higher intake of several artificial sweeteners to faster cognitive decline over about eight years, but it did not prove causation.
