Using light to reprogramme the brain’s GPS
10 November 2020
Neuroscientists in the Hausser lab have used laser beams to “switch on” neurons in mice, providing new insight into the hidden workings of memory and showing how memories underpin the brain’s inner GPS system.
The study, published in the journal Cell, explains how researchers harnessed an ‘all-optical’ approach using twin lasers to simultaneously read and write the activity of ‘place cells’ (a type of neuron) in mice, as they navigated a virtual reality environment. Read more
