#Psychedelics Sync Neurons: A Glimpse into #Consciousness & #Psychosis https://lnkd.in/g7J-BYEC Summary: Researchers have pioneered a method to simultaneously measure electrical signals from 128 brain regions in conscious rats. Using this technique, they observed the effects of psychedelic drugs, LSD and ketamine, on the brain’s neural oscillations. Despite their different modes of action, both drugs induced similar wave patterns across the brain. This synchronization might offer insights into understanding consciousness and potential research models for psychoses. Key Facts: 1 The study found that while LSD and ketamine impact different brain receptors, they produce similar wave patterns, indicating synchronized neural behavior. 2 This synchronized neural activity might be more linked to the psychedelic experience than the activity of individual neurons. 3 The observed wave patterns may serve as a valuable research model for studying psychoses and the neural basis of consciousness. The results show an unexpected and simultaneous synchronization among neurons in several regions of the brain. The idea that electrical oscillations in the brain could be used to teach us more about our experiences was conceived several years ago. Pär Halje and the research team was studying rats with Parkinson’s disease that had problems with involuntary movements. The researchers discovered a tone—an oscillation or wave in the electrical fields—of 80 hertz in the brains of the rats with Parkinson’s disease. It turned out that the wave was closely connected to the involuntary movements. “A Polish researcher had observed similar waves after giving rats the anesthetic ketamine. The ketamine was given at a low dose so that the rats were conscious, and the equivalent dose in a human causes psychedelic experiences. “The waves they saw were in more cognitive regions of the brain than in the rats with Parkinson’s, and the frequency was higher, but that still made us consider whether there were links between the two phenomena. “Perhaps excessive brain waves in the motor regions of the brain cause motor symptoms, while excessive waves in cognitive regions give cognitive symptoms,” says Pär Halje, researcher in neurophysiology at Lund University. Research model for psychoses Can the waves reveal more about consciousness?

It has been 100 years since the invention of Electroencephalography (EEG), and in that time, it has revolutionised brain research and diagnosis. From understanding cognition and memory to treating brain disorders like epilepsy, see the incredible impact EEG has had on neuroscience!

Fascinating research for a Sunday read from last November and recently featured in Neuroscience news - "Brain Stimulation Unlocks Our Telepathy and Clairvoyance Powers" Key Facts: 1. The study hypothesizes that the human brain acts as a filter suppressing innate psi abilities. 2. rTMS-induced lesions in the left medial middle frontal region led to significant psi effects. 3. This research could fundamentally change how psi phenomena are understood and studied. So, in theory by suppressing the activity of the left left medial middle frontal region, we could enhance our psychic abilities ? Max Tran is this the proof of the Gateway Experience ? What do you all think to this? Morris Freedman, Malcolm A. Binns, Jed A.

I am not surprised at the parallel pathway Chaos——Making a new science, makes no sense: synchrony=order paradox All the sync systems are spontaneous process which obey the second law of thermodynamics, mathematical description may not solve the problem: “How does order emerge out of chaos”. In reality, all sync systems are counterintuitive: order is disorder; disorder(chaos) is order. When sync is phase locked, energy is even, and entropy reaches maximum; when sync is phase unlocked, energy distribution is uneven, and entropy decreases. Your brain cells act just like school of birds and fish are in sync. All these sync systems obey the second law of thermodynamics, which entropy reached maximum. When brain cells are in sync, without any extra energy input, the sync will last as long as your life. Sync is energy conservative system which is spontaneous process as well as our memories, imagine some events happened in your childhood. So, let it go! Sync yourself! https://lnkd.in/dueSwvV https://lnkd.in/e2uRx_4t

"Researchers studied mice to understand how the brain processes unexpected stimuli during development. They found that the brain’s response to surprises changes as we grow, becoming more efficient in categorizing stimuli as “important” or “uninteresting.” This developmental change helps conserve energy by reducing excessive reactions to familiar surprises. The study also revealed that the brain regions responsible for processing surprises mature at different rates, with the cerebral cortex maturing later, akin to the early 20s in human years. Experience with sounds plays a crucial role in this development." #neuroscience #brain #uncertainty

In a recent study published in Nature Human Behaviour led by Josh Jacobs at Columbia University, monitored neural activity in 93 individuals recalling and forming memories. They discovered a previously unrecognized brainwave phenomenon called traveling waves, which move across the brain's cortex in various directions during memory tasks. The direction of these waves correlates with #memory processes: moving from back to front during encoding and front to back during recall. This dynamic understanding of #brainwaves challenges previous notions of static brain activity and opens avenues for predicting behavior and developing diagnostic and therapeutic tools for memory-related disorders. The study also hints at understanding other cognitive functions beyond memory. #brainwaves #cognitive #neuroscience Link: https://lnkd.in/euVjFEeV Link to original study in comments.

In a study, researchers have uncovered the role of the LPFC (lateral prefrontal cortex) in maintaining focus and filtering distractions. The study suggests that these visual-movement neurons act like traffic directors for the brain, ensuring attention is directed towards the most crucial tasks. Interestingly, findings also hint at the possibility that one's ability to focus might be improved, especially valuable for people with attention deficits.
