Researchers discover what’s behind a sense of direction

Using virtual reality experiments, Harvard neuroscientists have decoded how fruit fly brains integrate visual cues for navigation. Study also sheds light on a form of short-term memory known as unsupervised learning.

Harvard researchers explore macular degeneration through a new lens

Researchers have created the first cellular atlas of the primate retina and discovered that, while the fovea and peripheral retina share most of the same cell types, the cells are in different proportions, and show different gene expression patterns.

New technique enables subcellular imaging of brain tissue 1,000X faster than other methods

Combining two recently developed technologies — expansion microscopy and lattice light-sheet microscopy — researchers have developed a method that yields high-resolution visualizations of large volumes of brain tissue, at speeds roughly 1,000 times faster than other methods.

Researchers identify pathway that drives sustained pain following injury

Harvard researchers have identified in mice a set of neurons responsible for sustained pain and pain-coping behaviors. The new study is the first one to map out how these responses arise outside the brain.
