Understanding Multiscale Entropy
Multiscale entropy extends sample entropy to multiple time scales or signal resolutions to provide an additional perspective when the time scale of relevance is unknown….
Vitamins for the Brain
Vitamins play a crucial role in building axon fiber and facilitating synaptic transmission but have to be ingested to become available to the brain. Surprisingly,…
Getting Rid of Eye Blink in the EEG
The eye blink is one of the most common contaminants of the EEG signal. Here we discuss some common techniques used to remove it including…
Beyond the Brain: Embodied Cognition
The feedback loops between brain and body are profound, leading to the possibility that cognition is not simply a function of the brain alone but…
Down a Rabbit Hole? A History of EEG Analysis
The analysis of the EEG signal in terms of frequency bands has its origins in the technical workarounds of the 1930s when there were no…
Many Ways to Measure Attention
Attention is a multifaceted, multisensory cognitive phenomenon that can be studied in many ways. Here we describe a few methods used in the lab to…
Ethics in EEG
New directions and applications in EEG have significant implications for the future of society and raise the need for ethics frameworks. Last week the South…
The Illusion of Reality
Optical illusions demonstrate how our brains filter sensory stimulii and fit it into a construct that ‘makes sense’ to us. Can we measure our…
Alpha, Alpha Everywhere: What Does it Mean?
Activity in the alpha band has been a subject of much interest since the first recording of EEG. However methodological inconsistencies and confounding changes across…
