Memory Recall in Rett Mice Improved By Activating Brain Cells

Scientists were able to improve memory recall in Rett syndrome mice by activating a set of inhibitory brain cells called somatostatin-expressing interneurons (SOM), in part by using a miniature microscope that allowed them to monitor the animals’ neurons. Deficiencies in the SOM nerve cells contributed to impairments in long-term…
