Age-related memory decline and neurodegenerative diseases like Alzheimer's are often thought of as irreversible. But the brain is not static; neurons continually adjust the strength of their ...

The human brain is made up of billions of nerve cells (neurons) that communicate with each other in vast, interconnected networks. For the brain to function reliably, there must be a fine balance ...

To stay in balance, the brain depends on two types of neurons: Excitatory neurons (in white), which increase activity, and inhibitory neurons (in black), which damp down signals. Scientists have now ...

Researchers at Peking University have developed DUET, a breakthrough dual-color miniature two-photon microscope that ...

The same memory can feel vivid and accessible one moment, yet stubbornly out of reach the next - even when the memory itself remains intact.

Age can make memory feel like something that only moves in one direction. A name slips away. A route you know well turns fuzzy. In Alzheimer's disease, that slide can look even steeper. Yet the brain ...

The reward prediction error (RPE) hypothesis posits that phasic dopamine (DA) activity in the ventral tegmental area (VTA) encodes the difference between expected and ...

Sensing the content of ingested food is critical for the body to evaluate energy availability and accordingly set an adequate metabolic state. In addition to peripheral taste receptors, animals and ...
