For a review explaining these different mechanisms, see Working Memory Brain Training Mechanisms.
I am a cognitive scientist specializing in health, resilience and performance (HRP) brain training interventions and self-quantification. I have a joint Ph.D in cognitive psychology and neuroscience from the Center of the Neural Basis of Cognition (Carnegie Mellon/Pittsburgh) and for a number of years was a researcher and lecturer at Cambridge University.
Isn’t that a picture of a lower motor neuron, that’s white matter, not grey matter? Am I being scammed here?
No! Have a look at brain training mechanisms for relevant references and more extensive explanation. Every item is well supported.
Really? Has it ever worked for anyone here? It’s somehow similar to some IQ prep on an IQ research blog. As Neuroscientia works excellently, this might be worth giving a trial too, anyway.
