Sylvius Lectures

Sylvius Lectures

sylvius1The Sylvius Lectures refer to a prestigious lecture series organized and funded by the Leiden Institute for brain and Cognition (LIBC). Named after the German-Dutch physiologist and anatomist Franciscus Sylvius, discoverer of the brain’s Sylvian fissure, who died in Leiden in 1672, this annual lecture series presents a set of five or six internationally renowned speakers. Research areas of these invited speakers relate to one of the LIBC hot spots, i.e. Junior (brain development), Language, Stress or Pharmacology. The lectures are for free and open to all interested parties, and no registration is required.

In this talk I will discuss research from our laboratory that has examined what neural markers, both anatomical and functional, are associated with differences amongst individuals in their level of Executive Function.  In our laboratory we use the theoretical framework of Miyake & Friedman, which posits at least three major aspects of Executive Function:  A common factor, that is required across all Executive Function tasks, as well as two specific factors, one related to Working Memory Updating and the other related to Task Shifting.  We have found that distinct brain regions are associated with individual differences in each of these factors.  Furthermore, despite the fact that most all theories of Executive Function posit a critical role for lateral prefrontal cortex, our work indicates that individual differences in Executive Function are also highly associated with variation in other brain regions.  A tentative theory regarding these factors will be discussed.
