Inter and intra person variability in brain metrics across the population can result in misleading interpretation of results. It is important to understand the distributions…

A First Test of Hierarchical Adaptations
Are there hierarchical adaptations in the nervous system that help rapidly adapt responses to changing circumstances? A hypothetical experiment with the patellar reflex can help…
How the Power Grid Has Shaped EEG Research
Power line noise at 50 and 60 Hz is bang in the middle of the spectrum of brain activity and is often picked up by…
From Neurons to Concepts
How does the brain store concepts and activate them in a contextual manner? AI ignores concepts, connectionist models of the brain ignore concepts. What can…
Astrocytes in Charge
Over the last decade or so it has been found that astrocytes exert control over synapse formation, synaptic transmission, blood flow and host of other…
How are Concepts Created in the Brain?
A concept is a general notion or construct of something that doesn’t necessarily need all the pieces exactly and depends on context. How does the…
A Primer on the Application of Graph Theory to EEG
Graph theory has been most commonly used to understand the structure of social networks and has gained traction in the last decade as an important…
Alpha Energy – Specifically Estimating the Alpha Oscillatory Component in the EEG
The Alpha Energy metric specifically characterizes the periodic alpha components of the EEG that shows up as a peak above the background decay of the…
Adaptive Mechanisms and Afterimages
Afterimages are color inverted perceptual images that persist after fixating on an image for a long period of time. The perceptual mechanisms of afterimages suggest…
A New Metric of Waveform Complexity in EEG Analysis
It is yet unclear which features of the EEG signal are the most informative about brain states and outcomes. A new complexity measure with different…
