Metacognition affects every aspect of human behavior from defining life goals to judging our own senses. Researchers say brain activity related to confidence is also associated with goal-driven behaviors, shedding light on the neurobiological basis of metacognition.
Drums, dance, sleep deprivation, and drugs, referred to as the 4D's in the rave scene was associated with personal transformation for those who considered a rave to be an awe-inspiring event. The more a person felt personally transformed by the experience, the more bonded to the fellow ravers they felt. This phenomenon may explain the long-standing popularity of the rave scene.
Brain activity during conscious wakefulness presents large integrated and dynamic network modules which fragment during sleep.
A new statistical model lays groundwork for understanding how ketamine induces an anesthetic response, steps to monitor unconscious patients, and provides new information about brain activity while unconscious.
Eight weeks of meditation training enhanced brain connectivity between the default mode network and the dorsal attention network, allowing participants to quickly switch between mind wandering states and focused attention.
The release of 2-AG, a natural endocannabinoid that is suggested to be the brain's equivalent to THC, dampens down seizure activity but increases post-seizure oxygen deprivation in the brain.
People who practice meditation often report feeling "pure awareness" in which they say they experience consciousness itself. The state encompasses specific sensations and non-specific feelings, thoughts, and perceptions. Researchers say their findings will help explain "pure consciousness," and work to generate a prototypical minimal model for human conscious perception.
Study reveals people who experience intense visual imagery during a Ganzflicker test have naturally lower frequency rhythms in the visual cortex, making them more susceptible to pseudo-hallucinations.
Following a potentially life-threatening event, people often report seeing their "lives flashing before their eyes", where a multitude of memories from life events are recalled almost instantaneously. Researchers present theories on why this phenomenon may occur.
Giving up the theory that consciousness is like a "ghost in the machine" to focus on the neurobiology of brain mechanisms behind conscious awareness is an essential step to better understand the human mind, researchers argue.
