Researchers have created a hairlike device for long-term, non-invasive monitoring of the brain's electrical activity. The lightweight and flexible electrode attaches directly to the scalp and delivers ...

Humans have long wondered when and how we begin to form thoughts. Are we born with a pre-configured brain, or do thought patterns only begin to emerge in response to our sensory experiences of the ...

Trying to document how single brain cells participate in networks that govern behavior is a daunting task. Brain probes called Neuropixels, which feature high-density silicon arrays, have enabled ...

Hans Berger recorded the first human EEG in 1924. EEG records electrical activity via 16–25 scalp electrodes. Focal “slowing” in brain waves can indicate tumors or lesions. Patients must avoid ...
