Brain oscillations reveal that our senses do not experience the world continuously
(Medical Xpress) -- It has long been suspected that humans do not experience the world continuously, but rather in rapid snapshots.

Ketamine found to increase brain noise
An international team of researchers including Sofya Kulikova, Senior Research Fellow at the HSE University-Perm, found that ketamine, being an NMDA receptor inhibitor, increases the brain's background noise, causing higher ...

Neuroscience research provides evidence the brain is strobing, not constant
It's not just our eyes that play tricks on us, but our ears. That's the finding of a landmark Australian-Italian collaboration that provides new evidence that oscillations, or 'strobes', are a general feature of human perception.

Waves move across the human brain to support memory
The coordination of neural activity across widespread brain networks is essential for human cognition. Researchers have long assumed that oscillations in the brain, commonly measured for research purposes, brain-computer ...

Perceive this: The human brain controls alpha-band oscillation phase to effect temporal predictions
Standard models of perception are stimulus-driven, meaning that the external perceptual event drives the brain's perception-related activity. However, the tide may be turning: recent ideas suggest that our perceptual experiences ...

Does our life flash before our eyes during death?
Neuroscientists have recorded the activity of a dying human brain and discovered rhythmic brain wave patterns around the time of death that are similar to those occurring during dreaming, memory recall and meditation. Now, ...

Neuroscientists demonstrate how to improve communication between different regions of the brain
Selective communication among brain regions is crucial for brain function. But the weak and sparse connectivity of the brain is a big hurdle. During the last decade neuroscientists have identified various means by which this ...

How the brain consolidates memory during deep sleep
Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, despite ...

Crossing the channel: Surprising new findings in the neurology of sleep and vigilance
(Medical Xpress)—A recent neurological addressing one of the most fundamental issues in sleep rhythm generation study underscores an inconvenient truth—namely, that established scientific facts have and will continue ...

Study reveals a universal pattern of brain wave frequencies across mammalian species
Throughout the brain's cortex, neurons are arranged in six distinctive layers, which can be readily seen with a microscope. A team of MIT neuroscientists has now found that these layers also show distinct patterns of electrical ...

Oscillation
Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes is used to be synonymous with "oscillation". Oscillations occur not only in physical systems but also in biological systems and in human society.
