Brain areas underlying visual mental imagery and visual perception: an fMRI studyGiorgio Ganis
Department of Psychology, Harvard University, Cambridge, MA 02138, USA
Brain Res Cogn Brain Res 20:226-41. 2004..This finding may indicate that cognitive control processes function comparably in both imagery and perception, whereas at least some sensory processes may be engaged differently by visual imagery and perception...- Transcranial magnetic stimulation of primary motor cortex affects mental rotationG Ganis
Department of Psychology, Harvard University and Laboratory for Magnetic Brain Stimulation, Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, MA, USA
Cereb Cortex 10:175-80. 2000.... - Understanding the effects of task-specific practice in the brain: insights from individual-differences analysesGiorgio Ganis
Department of Psychology, Harvard University, 33 Kirkland St, Cambridge, MA 02138, USA
Cogn Affect Behav Neurosci 5:235-45. 2005..In short, individual-differences analyses provided insights into the relation between changes in brain activation and changes in accompanying performance, and these insights were not provided by standard group-based analyses... - Visual imagery in cerebral visual dysfunctionGiorgio Ganis
Department of Psychology, Harvard University, 33 Kirkland Street, Cambridge, MA 02138, USA
Neurol Clin 21:631-46. 2003..The brain is an enormously intricate organ, and even within a circumscribed domain such as imagery it seems to process information in complex and subtle ways... - An electrophysiological study of scene effects on object identificationGiorgio Ganis
Department of Psychology, Harvard University, Cambridge, MA 02138, USA
Brain Res Cogn Brain Res 16:123-44. 2003..We speculate that the N390 scene congruity effect reflects the action of visual scene schemata stored in the anterior temporal lobe... - Neural correlates of different types of deception: an fMRI investigationG Ganis
Department of Psychology, Harvard University, Cambridge, MA 02138, USA
Cereb Cortex 13:830-6. 2003..At least in part, distinct neural networks support different types of deception... - The role of area 17 in visual imagery: convergent evidence from PET and rTMSS M Kosslyn
Department of Psychology, Harvard University, Cambridge, MA 02138, USA
Science 284:167-70. 1999..In sum, the PET results showed that when patterns of stripes are visualized, Area 17 is activated, and the rTMS results showed that such activation underlies information processing... - Four types of visual mental imagery processing in upright and tilted observersFred W Mast
Department of Psychology, Harvard University, William James Hall, 33 Kirkland Street, Cambridge, MA 02138, USA
Brain Res Cogn Brain Res 17:238-47. 2003..Performance in the image composition and detection tasks depended on body position, whereas there was no such effect for the transformation and resolution tasks... - Detecting concealed knowledge using a novel attentional blink paradigmGiorgio Ganis
Department of Radiology, Harvard Medical School, Boston, MA 02114, USA
Appl Psychophysiol Biofeedback 34:189-96. 2009.... - Neural processes underlying self- and other-related lies: an individual difference approach using fMRIGiorgio Ganis
Harvard Medical School, Boston, Massachusetts, USA
Soc Neurosci 4:539-53. 2009..The results confirmed both hypotheses and supported the utility of this individual differences approach in the study of deception in particular, as well in the study of complex cognitive phenomena more generally... - Visual mental imagery and perception produce opposite adaptation effects on early brain potentialsGiorgio Ganis
Department of Radiology, Harvard Medical School, Boston, MA 02115, USA
Neuroimage 42:1714-27. 2008..These findings support image-percept equivalence theories and may explain, in part, why visual percepts and visual mental images are not routinely confused, even though both engage similar neural populations in the visual system... - Neuroimaging evidence for object model verification theory: Role of prefrontal control in visual object categorizationGiorgio Ganis
Department of Radiology, Harvard Medical School, Boston, MA 02115, USA
Neuroimage 34:384-98. 2007.... - Repetitive transcranial magnetic stimulation of human area MT/V5 disrupts perception and storage of the motion aftereffectHugo Theoret
Laboratory for Magnetic Brain Stimulation, Beth Israel Deaconess Medical Center, Harvard Medical School, 330 Brookline Avenue, KS 454, Boston, MA 02215, USA
Neuropsychologia 40:2280-7. 2002..These data provide experimental support for the notion that MT/V5 subserves perception and storage of the motion aftereffect... - Lying in the scanner: covert countermeasures disrupt deception detection by functional magnetic resonance imagingGiorgio Ganis
Department of Radiology, Harvard Medical School, Boston, MA 02115, USA
Neuroimage 55:312-9. 2011..These findings show that fMRI-based deception detection measures can be vulnerable to countermeasures, calling for caution before applying these methods to real-world situations... - Hand response differences in a self-face identification taskJ P Keenan
Department of Neurology, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA 02215, USA
Neuropsychologia 38:1047-53. 2000..The data suggest that participants are inclined to identify images as their own when the right hemisphere is preferentially accessed... - Frontostriatal circuits are necessary for visuomotor transformation: mental rotation in Parkinson's diseaseMelissa M Amick
Department of Psychology, Boston University, 648 Beacon Street, 2nd Floor, Boston, MA 02215, USA
Neuropsychologia 44:339-49. 2006..Moreover, frontostriatal motor systems and the parietal lobes play a necessary role during the mental rotation of hands, which requires integrating visuospatial cognition with motor imagery... - Assessing the neural correlates of self-enhancement bias: a transcranial magnetic stimulation studyVirginia S Y Kwan
Department of Psychology, Princeton University, Princeton, NJ, USA
Exp Brain Res 182:379-85. 2007..Together, these findings suggest that the MPFC may influence self-enhancement... - Visual cortex excitability increases during visual mental imagery--a TMS study in healthy human subjectsRoland Sparing
Laboratory for Magnetic Brain Stimulation, Department of Neurology, Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, MA 02214, USA
Brain Res 938:92-7. 2002..These findings demonstrate for the first time a short-term, task-dependent modulation of PT. These results constitute evidence that early visual areas participate in visual imagery processing...
