Evidence has amassed from both animal intracranial recordings and human
electrophysiology that neural oscillatory mechanisms play a critical role in a number of …

The most salient electrical signal measured from the human brain is the α-rhythm, neural
activity oscillating at∼ 100ms intervals. Recent findings challenge the longstanding dogma …

Decreases in alpha synchronization are correlated with enhanced attention, whereas alpha
increases are correlated with inattention. However, correlation is not causality, and …

Visual illusions and hallucinations are hallmarks of serotonergic hallucinogen-induced
altered states of consciousness. Although the serotonergic hallucinogen psilocybin activates …

Unraveling how brain regions communicate is crucial for understanding how the brain
processes external and internal information. Neuronal oscillations within and across brain …

Using a common set of mindfulness exercises, mindfulness based stress reduction (MBSR)
and mindfulness based cognitive therapy (MBCT) have been shown to reduce distress in …

Listening to speech is often demanding because of signal degradations and the presence of
distracting sounds (ie,“noise”). The question how the brain achieves the task of extracting …

Attention plays a fundamental role in selectively processing stimuli in our environment
despite distraction. Spatial attention induces increasing and decreasing power of neural …

The functional significance of the α rhythm is widely debated. It has been proposed that α
reflects sensory inhibition and/or a temporal sampling or “parsing” mechanism. There is also …

There have been a number of studies suggesting that oscillatory alpha activity (~ 10 Hz)
plays a pivotal role in attention by gating information flow to relevant sensory regions. The …
