Brain organoids engineered to carry the genetic material could reveal how our brains are similar to and different from those of our closest relatives.

Injecting molecules from a sea slug that received tail shocks into one that didn’t made the recipient animal behave more cautiously. 

A new technique reveals certain neuronal connections grow larger and denser when memories are made.

Neural plasticity wanes with age, but increasing the protein Arc—abundant earlier in life—in the visual cortex of mice can fend off this decline.

In mice, injected fragments of a naturally occurring protein boost memory in young and old animals and improve cognition and mobility in a model of neurodegenerative disease. 

Scientists block particular enzymes to remove the cellular signatures associated with specific memory types.  

The UCLA neurobiologist uses computational modeling, in vitro electrophysiology, and human psychophysics experiments to explore how neurons and the brain as a whole perceive and respond to time.

Why can science still not define this most basic biological process?

Using optogenetics, researchers excite selected neurons to reinstate a fear memory that had been blocked.
