Building The Brain With Modules
Models in computational neuroscience that solve for one outcome cannot combine with one that solves for another. Can a modular approach solve this? The short…
The Crisis of Computational Neuroscience
Computational Models attempt to explain the behavior of the brain using neural network simulations, but assumptions that help simulate one phenomenon are destructive to the…
Assessing Connectivity with Phase Locking Value
Assessing phase locking in the signal between two electrodes is often used as a method to assess functional connectivity. Here is a look at how…
Why Do Brains Have Spontaneous Activity?
The brain spontaneously produces activity regardless of mental activity and stimulus input. Current theories treat this activity as noise or simply ignore it. What does…
Tracking Anesthesia
With multifaceted effects from analgesia, amnesia, paralysis and loss of consciousness the mechanisms of anesthesia are still a mystery. Can tracking with EEG provide deeper…
Factors that Impact Coherence in the EEG
Coherence is a commonly used measure in EEG analysis. What is Coherence and what are the practical considerations, limitations and interpretations of this measure when…
Neuronal Avalanches: What are They and What do They Mean?
Neuronal avalanches are a structure of organization of cascades of synchronized of activity in the cortex that have several surprising implications for how we understand…
Pitfalls of Filtering the EEG Signal
Filtering of the EEG signal to remove artifacts is a common pre-processing step but introduces temporal distortions in the signal. How do you chose a…
The Radically Changing View of the Cerebellum
Long thought to be purely involved in motor activity, new roles have been discovered for the cerebellum in cognition. Yet so long on a backfoot…
