Presentation Transcript

  1. fMRI – “Pluripotentiality” vs. “Degeneracy”

  2. H.R. Naghavi, L. Nyberg / Consciousness and Cognition 14 (2005) 390–425

  3. Pluripotentiality (one to many) Function 3 Structure A Function 2 • State functions? • Common processing stage? • Or • True pluripotentiality? Function 1 • If pluripotentiality – at what level? Lobe? Region? Ansemble? Single neuron?

  4. Degeneracy (many to one) Structure C Function 1 Structure B Structure A • Different normal strategies? • Normal anatomical variation?

  5. Level of description determines Pluripotent\Degenerate • Structure: • Multiple regions (network) • Single regions • Neuronal assemplies\populations • Single neurons • Function • E.g. “sentence comprehension” vs. [word recognition; working memory; syntactic parsing…”

  6. Degenerate or not? קריאת מילים “orthographic” “phonology”

  7. The spatial resolution • Intrinsic resolution is determined by the physiology • Precision depends on the voxel size + distrotions • Distinguishing two foci is hindered by intersubject variability • Neuronal adaptation technique
