How the Brain Filters out Distracting Thoughts to Focus on a Single Bit of Information
The human brain is bombarded with all kinds of information, from the memory of last night's delicious dinner to the instructions from your boss at your morning meeting. But how do you "tune in" to just one thought or idea and ignore all the rest of w...
Frequency of gamma oscillations routes flow of information in the hippocampus
... function of gamma frequency variations in the brain and provide a mechanism for temporal segregation of potentially interfering information from different sources....
Local cortical lesions abolish lateral inhibition at direction selective cells in cat visual cortex
Many cells in the cat visual cortex display a strong selectivity for the direction of motion of an optimally oriented stimulus. Postsynaptic inhibition has been suggested to generate this direction selectivity in simple cells, but the intracortical p...
... through diet and chemical manipulation of the brain; or in the figurative sense, by altering the subject’s paradigm and perception of reality. Both of these transformations imply targeted neuroplasticity. The extreme diets and psychedelic medic...
What Geometric Visual Hallucinations Tell Us about the Visual Cortex
... this to mean that they are generated in the brain. Here, we summarize a theory of their origin in visual cortex (area V1), based on the assumption that the form of the retino–cortical map and the architecture of V1 determine their geometry. (...
... of experimental findings in the cortex and other brain regions. This is accomplished first by presenting a biophysically motivated derivation of the system and then by establishing a framework for comparison between numerical and experimental measur...
... an explanation and it all holds together. It's brain chemistry. It's neuropharmacology. It's quite possibly other realms. Whatever it is, it's the new frontier, a closer examination of consciousness, and it's very, very exciting!" (betaphilings.co...
Timewarp: How your brain creates the fourth dimension
... slow motion. Eagleman wanted to know whether the brain's clock actually accelerates - making external events appear abnormally slow in comparison with the brain's workings - or whether the slo-mo is just an artefact of our memory. It's just one o...
... when stimulated by light, send signals to the brain. These signals are subsequently interpreted as vision. Most of the receptors are rods, which are found predominately in the periphery of the retina, whereas the cones are located mostly in th...
Information Processing in Human Body
We can think about the human body as a self-organized collective of clones of a single fertilized egg cell. Each cell of the human body is an elaborate bio-chemical computer. It has its own power management and information processing structures. It c...
The Control Interrupt Model of Psychedelic Action
The brain is an information processing organ that uses top-down signal modulation to control the flow of bottom-up sensory input. Feedback modulation of incoming signal is an example of self-stabilizing control in a signal processing system. Using th...
