How the Brain Filters out Distracting Thoughts to Focus on a Single Bit of Information

... of what is going on around you, until it comes time to think of something else? Researchers at the Kavli Institute for Systems Neuroscience and Centre for the Biology of Memory at the Norwegian University of Science and Technology (NTNU) have d...

Frequency of gamma oscillations routes flow of information in the hippocampus

... varies substantially across space and time, from approx25 to almost 150 Hz1, 9, 10, 11, 12, 13. Here we show that gamma oscillations in the CA1 area of the hippocampus split into distinct fast and slow frequency components that differenti...

Chaotic fingerprints and space-time labyrinths

Video Feedback is a great example of real-time evolving self-organising systems near the edge of chaos. With a relatively simple camera-monitor/TV set-up you can produce a vast spectrum of time-based fractal species, many of which bare great similari...

Mathematical Neuroscience: From Neurons to Circuits to Systems

... canonical models demonstrates how neuronal spike-time statistics follow from simple properties of neurons. Averaging over space allows one to derive a simple model for the whisker barrel circuit and use this to explain and suggest several experiment...

Presynaptic regulation of recurrent excitation by D1 receptors in prefrontal circuits

... their capacity for sustained activity during the time a stimulus is held in memory, and this mnemonic response is considered a substrate for a variety of cognitive functions. The neuronal basis for sustained activity in prefrontal neurons is unknown...

Timewarp: How your brain creates the fourth dimension

... of many mysteries concerning how we experience time that we are only now beginning to crack. "Time," says Eagleman, "is much weirder than we think it is." By understanding the mechanisms of our brain's clock, Eagleman and others hope to learn w...

Effects of psilocybin on time perception and temporal control of behaviour in humans

...

The Control Interrupt Model of Psychedelic Action

... consciousness is constrained and focused on real-time ego behavior; nonlinear consciousness is unconstrained and goes wherever it is driven by input state variables, or set and setting. In order for a perceptual system to transition from a linear ...
