Resting brain activity can provide approximate maps of network organization in the brain. A new imaging technique allowed researchers to examine cortical architecture in greater detail than before in the living brain.
Information about new experiences is retained by being tied to pre-existing activity patterns in the brain. Memory is acquired when the patterns are connected to each other across brain regions via transient bursts of activity.
Researchers have developed a new AI algorithm that prevents smart devices such as Alexa or Siri from correctly hearing your words 80% of the time. The algorithm is a step toward providing personal agency in protecting the privacy of their voice in the presence of smart devices.
