Cerebellar activation during copying geometrical shapes

Autor: Maria-Alexandra Georgopoulos, Kâmil Uğurbil, Nikolaos V. Tsekos, Charidimos Tzagarakis, Seong-Gi Kim, Bagrat Amirikian, Scott M. Lewis, Trenton A. Jerde, Apostolos P. Georgopoulos

We studied functional MRI activation in the cerebellum during copying 9 geometrical shapes (equilateral triangle, isosceles triangle, square, diamond, vertical trapezoid, pentagon, hexagon, circle, and vertical lemniscate). Twenty subjects were image

Parametric statistical analyses of BOLD fMRI data often assume that the data are normally distributed, the variance is independent of the mean, and the effects are additive. We evaluated the fulfilment of these conditions on BOLD fMRI data acquired a

Figure copying in Williams syndrome and normal subjects

Autor: Nicole Kuz, Barbara Landau, Apostolos P. Georgopoulos, Maria Alexandra Georgopoulos

Publikováno v: Experimental Brain Research. 157

We evaluated the copying abilities of ten subjects with Williams syndrome (WS; age 6-14 years) and ten normally developing children (age 3-6 years) matched for mental age using the matrices component of the Kaufman Brief Intelligence Test (mKBIT). Ea

Functional magnetic resonance imaging of visual object construction and shape discrimination : relations among task, hemispheric lateralization, and gender

Autor: Kâmil Uğurbil, Kenneth Whang, Bagrat Amirikian, Maria-Alexandra Georgopoulos, Seong-Gi Kim, Georgios A. Tagaris, Wolfgang Richter, Apostolos P. Georgopoulos

Publikováno v: Journal of cognitive neuroscience. 13(1)

We studied the brain activation patterns in two visual image processing tasks requiring judgements on object construction (FIT task) or object sameness (SAME task). Eight right-handed healthy human subjects (four women and four men) performed the two
