In their wonderful Neuroimage article, Braun & Mattia present a comprehensive introduction to the possible neuronal implementations and cognitive sequelae of a particular dynamical phenomenon: the attractor state. In another excellent paper, just recently out in Frontiers, Itskov, Hansel and...

If you ever said to yourself, "I wonder whether the human mid- and posterior ventrolateral prefrontal cortex has a homologue in the monkey, and what features of its cytoarchitecture or subcortical connectivity may differentiate it from other regions of PFC"...

Soups that taste like garlic have garlic in them; you observe two people eating soup; one of them says to the other, "There is no garlic in this soup." Does the soup taste like garlic? If you said yes, then you've just committed a fallacy so absurd it's only recently been given a name.

Last month's Frontiers in Psychology contains a fascinating study by Dambacher, Hübner, and Schlösser in which the authors demonstrate that the promise of financial reward can actually reduce performance when rewards are given for high accuracy. Counterintuitively, performance (characterized as...

Owing to the low signal-to-noise ratio of functional magnetic resonance imaging, it is difficult to get a good estimate of neural activity elicited by task novelty: by the time one has collected enough trials for a good estimate, the task...

How do we detect important items in our environment? This crucial capacity has received less attention than one might think, and a number of extremely basic issues remain to be explored. For example, it has long been known that target...

Sometimes, ground-breaking studies don't get the attention they deserve - even from experts in the field. One great example of this is an elegant study by Nieuwenhuis et al. from CABN in 2003; in it, they conclusively demonstrate why a...

Somehow, support vector machines learned the characteristic features of functional change in neural connectivity between the ages of 7 and 30 years. How exactly did they manage this?

It's clear from decades of research that induction of function is the wrong way to interpret the effects of neurostimulation. So why would we make that inference here and not in other single pulse studies?

Yesterday's introduction to paired-pulse transcranial magnetic stimulation elicited an insightful from reader Kix, who seems to agree that both disruption and induction of function could occur via TMS simultaneously. But this is a serious problem: how could we ever pin the tail on the donkey?
