Dreaming: A peculiar form of cognitive activity

Dreams are a complex phenomenon that most people experience during sleep. They are characterized by a series of thoughts, images, and emotions that are felt and recalled sometimes with high vividness. Such activity is associated with the so-called rapid eye movement (REM) sleep phase, which entails a separate phase from the no-REM (NREM) sleep cycle. Brainwave activity linked to REM sleep resembles that of the waking brain making it hard to distinguish between them. Recently, new research has found for the first time a novel brain pattern that allows predicting when someone is dreaming and even the content of dreams. In this post, you will get to know better what is going on in the brain when you dream and the purpose of dreaming.

Binaural Beats as Brain Enhancers: is there any Scientific Proof?

Maybe you have heard of binaural beats, a soundwave stimulus that has spread across the internet for having positive effects on mood and cognition. Binaural beats are auditory illusions that occur when presenting two tones with a slight frequency mismatch to each ear separately. Some evidence support that such acoustic stimulation can train the brain signals, altering both, specific brainwaves and connectivity patterns. Other evidence indicates just placebo effects suggesting no better benefits than monoaural beat stimuli. Today, the assumed exceptional effects of binaural beats on human emotion and cognition remain still unclear. Regardless of such discrepancies, what is the scientific evidence of its claimed effects on the human brain?
