Brown University creates first wireless, implanted brain-computer interface

Brown University creates first wireless, implanted brain-computer interface | Digital Culture | Scoop.it

Brown’s wireless BCI, fashioned out of hermetically sealed titanium, looks a lot like a pacemaker. Inside there’s a li-ion battery, an inductive (wireless) charging loop, a chip that digitizes the signals from your brain, and an antenna for transmitting those neural spikes to a nearby computer. The BCI is connected to a small chip with 100 electrodes protruding from it, which, in this study, was embedded in the somatosensory cortex or motor cortex. These 100 electrodes produce a lot of data, which the BCI transmits at 24Mbps over the 3.2 and 3.8GHz bands to a receiver that is one meter away. The BCI’s battery takes two hours to charge via wireless inductive charging, and then has enough juice to last for six hours of use.

Once considered mainly 'brain glue,' astrocytes' power revealed

Once considered mainly 'brain glue,' astrocytes' power revealed | Digital Culture | Scoop.it

A type of cell plentiful in the brain, long considered mainly the stuff that holds the brain together and oft-overlooked by scientists more interested in flashier cells known as neurons, wields more power in the brain than has been realized, according to new research published March 29 in Science Signaling.

Should we sacrifice our brains to the Internet?

Should we sacrifice our brains to the Internet? | Digital Culture | Scoop.it

One of the greatest effects of the Internet is its ability to capture our attention only to scatter it, ultimately producing a generation whose brains are being better hardwired to scan, skim and multitask, causing a weakening in our ability to read and think deeply in a concentrated manner.
