Topographical disorientation: a synthesis and taxonomy
GK Aguirre, M D'Esposito - Brain, 1999 - academic.oup.com
Over the last century, several dozen case reports have presented `topographically disoriented'
patients who, in some cases, appear to have selectively lost their ability to find their way …

Event-related functional MRI: implications for cognitive psychology.
M D'Esposito, E Zarahn, GK Aguirre - Psychological bulletin, 1999 - psycnet.apa.org
Functional magnetic resonance imaging (fMRI) has rapidly emerged as a powerful technique
in cognitive neuroscience. We describe and critique a new class of imaging experimental …

Neural components of topographical representation
GK Aguirre, E Zarahn… - Proceedings of the …, 1998 - National Acad Sciences
Studies of patients with focal brain damage suggest that topographical representation is
subserved by dissociable neural subcomponents. This article offers a condensed review of the …

Role of left inferior prefrontal cortex in retrieval of semantic knowledge: a reevaluation
…, M D'Esposito, GK Aguirre… - Proceedings of the …, 1997 - National Acad Sciences
A number of neuroimaging findings have been interpreted as evidence that the left inferior
frontal gyrus (IFG) subserves retrieval of semantic knowledge. We provide a fundamentally …

The variability of human, BOLD hemodynamic responses
GK Aguirre, E Zarahn, M D'Esposito - Neuroimage, 1998 - Elsevier
Cerebral hemodynamic responses to brief periods of neural activity are delayed and dispersed
in time. The specific shape of these responses is of some importance to the design and …

Empirical analyses of BOLD fMRI statistics
E Zarahn, GK Aguirre, M D'Esposito - Neuroimage, 1997 - Elsevier
Temporal autocorrelation, spatial coherency, and their effects on voxel-wise parametric
statistics were examined in BOLD fMRI null-hypothesis, or “noise,” datasets. Seventeen normal, …

The parahippocampus subserves topographical learning in man
The hippocampus has been proposed as the site of neural representation of large-scale
environmental space, based upon the identification of place cells (neurons with receptive fields …

[HTML][HTML] An area within human ventral cortex sensitive to “building” stimuli: evidence and implications
GK Aguirre, E Zarahn, M D'Esposito - Neuron, 1998 - cell.com
Isolated, ventral brain lesions in humans occasionally produce specific impairments in the
ability to use landmarks, particularly buildings, for way-finding. Using functional MRI, we …
