Effect of EEG Reference Choice on Outcomes
In EEG, voltages recorded at each electrode are computed with reference to another electrode. The choice of this electrode reference impacts a number of EEG measures….
Individual Variability in Adolescent Brain and Behavior
Little is known about the developmental trajectory of the brain through adolescence but a few studies suggest there is large inter-person variability and differences that…
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…
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…
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…
The Insidious Costs of Poor Scientific Data Management
Data takes time and money to collect and is the core raw material of a lab but often it is managed poorly and not utilized…
Turning Brainwaves to Sound
Turning brainwaves recorded with EEG into sound has a fifty year history in art. With clever approaches to the signal, ‘listening’ to the EEG can…
Intra-person Variability in the EEG
Our brain activity are in constant flux and fundamental aspects of the dynamics vary both across the brain and over time. For some people this…
