Neuroscience

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.

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.

Efforts to build a better digital “nose” suggest that our perception of scents reflects both the structure of aromatic molecules and the metabolic processes that make them.

When the brain encodes memories as positive or negative, one molecule determines which way they will go.

Dreams are subjective, but there are ways to peer into the minds of people while they are dreaming. Steven Strogatz speaks with sleep researcher Antonio Zadra about how new experimental methods have changed our understanding of dreams.
