Stimulation, Sensation and Localization in the Cortex
Some aspects of cortical localization are well established but it may be the atypical responses to cortical stimulation that hold the keys to the the…
Intelligence and Neuroscience
Intelligence research has been the domain of psychology and sociology and barely intersects with neuroscience. Yet intelligence has everything to do with the brain, and…
Source Localization in the EEG
Identifying the source within the brain from which an EEG signal element originates is a complex problem that requires a model of the head and…
The Inverse Problem in EEG – Assumptions and Pitfalls
Solving the inverse problem in EEG to identify the source of a signal requires a number of assumptions to constrain the solution space. These assumptions…
Brain in a Dish
Pieces of brain in a dish can give rise to synchronous electrical activity with similar characteristics to that measured in the intact brain. What aspect…
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…
