Brain Zaps Can Trigger Lucid Dreams
Lucid dreams, in which people are aware of and can control their dreams, are rare. But now scientists have found they can induce this weird state of mind in people by zapping their brains with a specific frequency of electricity.
A lucid dream can be thought of as an overlap between two states of consciousness — the one that exists in normal dreaming, and the one during wakefulness, which involves higher levels of awareness and control.
Future Brain Implants Will Restore Lost Memories
In the next few months, highly secretive US military researchers say they will unveil new advances toward developing a brain implant that could one day restore a wounded soldier's memory.
The Defense Advanced Research Projects Agency (DARPA) is forging ahead with a four-year plan to build a sophisticated memory stimulator
Brain Implants vs. Mental Disorders
The Defense Advanced Research Projects Agency, or DARPA, is launching a $70 million program to help military personnel with psychiatric disorders using electronic devices implanted in the brain.
The goal of the five-year program is to develop new ways of treating problems including depression, anxiety and post-traumatic stress disorder
How to Supercharge Your Brain With A Zap of Electricity
With a jolt of electricity, you might be able to enter a flow state that allows you to learn a new skill twice as fast, solve problems that have mystified you for hours
Researchers think that as we learn more about the brain, we'll be able to use electricity to boost focus, memory, learning, mathematical ability, and pattern recognition. Electric stimulation may also clear away depression and stave off cognitive decline
What Falling In Love Does to Your Brain
Falling in love causes our body to release a flood of feel-good chemicals that trigger specific physical reactions," said Pat Mumby, PhD, co-director of the Loyola Sexual Wellness Clinic and professor, Department of Psychiatry & Behavioral Neurosciences, Loyola University Chicago Stritch School of Medicine (SSOM). " Levels of these substances, which include dopamine, adrenaline and norepinephrine, increase when two people fall in love.
Scientists Build An 'Off' Switch for the Brain
Scientists have developed an "off-switch" for the brain to effectively shut down neural activity using light pulses.
n 2005, Stanford scientist Karl Deisseroth discovered how to switch individual brain cells on and off by using light in a technique he dubbed 'optogenetics'.
