How The Eye Forms Images

Our eyes continually move even while we fix our gaze on an object. Although these fixational eye movements have a magnitude that should make them visible to us, we are unaware of them. If fixational eye movements are counteracted, our visual perception fades completely as a result of neural adaptation. So, our visual system has a built-in paradox — we must fix our gaze to inspect the minute details of our world, but if we were to fixate perfectly, the entire world would fade from view. Owing to their role in counteracting adaptation, fixational eye movements have been studied to elucidate how the brain makes our environment visible. Moreover, because we are not aware of these eye movements, they have been studied to understand the underpinnings of visual awareness. Recent studies of fixational eye movements have focused on determining how visible perception is encoded by neurons.

Dreaming Is A DMT Experience

Image
Dimethyltryptamine, or DMT , is a potent psychedelic drug commonly found in nature. DMT is also produced by our brains and contribute to a wide variety of experiences. Scientists have also been intrigued by the possibility that DMT would be involved in, for example, the generation of psychedelic experiences or dreamlike states. This video will briefly examine the physiological function of endogenous DMT from a pharmacological perspective. You can get a chemical version of course, and the resulting trip or hallucination is very profound and many would say life changing. But there's a problem with reading loads of peoples stories about DMT and I think by reading and hearing about peoples stories, you're actually changing what might have happened to you if you'd never heard the stories. The same can be said of lucid dreaming, if you constantly hear things like 'when you lucid dream, you'll be met by the terrifying sleep paralysis demon' then you start to believe it

Dark Matter Transducer

Scientists are on a quest to solve one of physics’ biggest mysteries: What exactly is dark matter – the invisible substance that accounts for 85 percent of all the matter in the universe but can’t be seen even with our most advanced scientific instruments? Most scientists believe it’s made of ghostly particles that rarely bump into their surroundings; that’s why billions of dark matter particles might zip right through our bodies every second without us even noticing. Leading candidates for dark matter particles are WIMPs, or weakly interacting massive particles. SLAC (Stanford Linear Accelerator Center) National Accelerator Laboratory is helping to build and test the LUX-ZEPLIN or LZ detector, one of the biggest and most sensitive detectors ever designed to catch hypothetical dark matter particles known as WIMPs. Identifying the building blocks of dark matter is one of the highest priorities of modern physics. Most scientists believe it’s made of ghostly particles that rarely bump int

The Conscious Electromagnetic Information (CEMI) Field Theory

Image
Consider driving along a familiar road. You may be listening to the radio, thinking about some problem at work, but your brain is busy performing all the complex computations necessary to control your limb movements and maintain your car on the busy road, unconsciously. You spot a hazard sign 'Roadworks Major Congestion Ahead' and immediately your conscious mind takes control, to slow the car and perhaps try to find an alternative route home. What is it that is taking control in these situations? What we need to look for is something that is a product of the brains activity, that integrates information but which also has the power to influence that activity. Surprisingly, we have known for years that such an entity exists within our brain. The neurons in our brain transmit electrical signals along and between nerve fibers. It is always assumed that the electrons and neurotransmitters moving down these nerves are the movers and shakers of neuronal computation. However, all elect
