In the early days of functional magnetic resonance imaging (fMRI), researchers were eager to point out that the hemodynamic response measured by fMRI may correspond rather directly to neural firing. Recently, a number of researchers have attempted to remind the larger neuroimaging community that the hemodynamic response reflects metabolic/energetic demands, and this might very well…

When I started this blog back in ’06, new hypotheses were appearing on a possible functional architecture of the lateral prefrontal cortex – a recently-evolved brain area implicated in high-level cognitive functions like planning, analogical reasoning, and cognitive control. Since then, these hypotheses have been refined, and the results replicated numerous times. Today, it’s essentially…
