- Injectable Implants Could Help Crack the Brain’s Codes
A new type of flexible electronic device shows promise for long-term brain mapping and could be a more effective way to provide therapeutic stimulation.
Understanding how the brain works—or doesn’t, as the case may be—depends on deciphering the patterns of electrical signals its neurons produce. Recording them requires inserting electrodes into the tissue. But the rigid devices traditionally used to record these signals, or to therapeutically stimulate certain regions, can damage the brain and elicit an immune response, and they tend not to work for very long.
