The neural representations of a perceived image and the memory of it are almost the same. New work shows how and why they are different.

After decades in the shadow of the reigning model for Alzheimer’s disease, alternative explanations are finally getting the attention they deserve.

Researchers discover that to sharpen its control over precision maneuvers, the brain uses comparisons between control signals — not the signals themselves.

New research in fish suggests that gut microbes can have a crucial early influence on the brain’s social development.

Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex.

Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates.

The discovery of a hot spot for horizontal gene transfer draws attention to the possible roles of parasites and ecology in such changes.

With stem cell technology and lab-grown brain organoids, Sergiu Paşca seeks the causes of autism and other neuropsychiatric conditions.

Letting human brain organoids grow in animal brains could be an ethical new option for experimental studies of neurological disorders.
