SUMMARY:Basic number representations and their neural basis - Dr Wim Fias\

DESCRIPTION:Abstract: In the first part of my talk I will focus on basic n
 umber representations and how they are neurally implemented. Two types of 
 number coding can be distinguished: summation coding and number-selective 
 coding. I will discuss the results of computational modeling and fMRI stud
 ies that show how these number representations are functionally related an
 d integrated along an occipito-parietal network. \nIn the second part I wi
 ll focus on how these basic number representations are associated to space
 . It is commonly assumed that basic number representations are spatially c
 oded as a mental number line. Access to specific number representations is
  supposed to be mediated by mechanisms of spatial attention. I will presen
 t evidence from neglect patients and from behavioral experiments in health
 y controls that question this idea. An alternative framework is proposed.\
 n\nBio: Wim Fias obtained his PhD at the Laboratory for Experimental Pycho
 logy at University of Leuven (Belgium) in 1997. In 1999 he moved to the De
 partment of Experimental Psychology at Ghent University and established hi
 s research group focusing on the study of various aspects of numerical cog
 nition (basic representations\, asociations between number and space\, men
 tal arithmetic\, development\, etc) using different behavioral and neurosc
 ientific techniques (fMRI\, EEG\, patient studies). Later he extended his 
 research interests to cognitive and action control. He is currently coordi
 nating an interfaculty multidisciplinary research consortium at Ghent Univ
 ersity that focuses on the integrative neuroscience of behavior control. H
 e is co-director of the Institute of Neuroscience at Ghent University.
