Talk Title: "Reading Minds"?: Pre

dicting Mental Function from Neuroimaging Data

Talk Abstract:
Neuroi

maging tools have become increasingly powerful, to the degree that some in

vestigators have claimed to be able to "read minds" using functional MRI. I
will discuss our work which has examined the degree to which mental functi

ons can be predicted from neuroimaging data, focusing particularly on gene

ralization to new individuals. I will show that we can accurately classify

which of a large set of mental functions a person is engaged in, using cla

ssifiers trained on other individuals. I will also show that we can predict
individual variability in behavior using high-dimensional regression. Fina

lly, I will demonstrate how we can classify individuals using meta-analyti

c data derived from literature mining.

Speaker Bio:
Russ Poldrack re

ceived his Ph.D in Cognitive Psychology from the University of Illinois at

Urbana-Champaign. He was a postdoctoral fellow at Stanford, and held facul

ty positions at Harvard Medical School and UCLA before becoming Director of
the Imaging Research Center at the University of Texas at Austin. His rese

arch uses neuroimaging to understand the neural basis of decision making,

executive function, and learning. He has also written extensively on conce

ptual and analytic issues regarding fMRI. In addition, he is deeply involv

ed in the development of informatics resources for cognitive neuroscience,
including the Cognitive Atlas project and the OpenFMRI project. His resear

ch has received awards from the Organization for Human Brain Mapping (OHBM)
and American Psychological Association, and in 2009 he served as Chair of
the OHBM. He is as Associate Editor for Frontiers in Human Neuroscience,

and has served on the editorial boards for Trends in Cognitive Sciences, C

erebral Cortex, Human Brain Mapping, Cognitive Science, and Neuroimage.
