Optogenetics Controls Brain ‘Switchboard’ in Mice

Optogenetic techniques have been used to alter the attention spans of mice, helping to shed light on how the brain mediates internal thoughts and external distractions.

A team from New York University’s Langone Medical Center focused on the thalamic reticular nucleus (TRN) of the mouse brain. Introducing light-sensitive molecules into the region allowed the researchers to precisely control the firing patterns of visual TRN cells with laser pulses.
