Amygdala activation in response to 2D and 3D emotion-inducing stimuli
Dores, Artemisa Rocha; Barbosa, Fernando; Monteiro, Luís; Leitão, Miguel; Reis, Mafalda; Coelho, Carlos M.; Ribeiro, Eduardo; Carvalho, Irene P.Studying changes in brain activation according to the valence of emotion-inducing stimuli is essential in the research on emotions. Due to the ecological potential of virtual reality, it is also important to examine whether brain activation in response to emotional stimuli can be modulated by the three-dimensional (3D) properties of the images. This study uses functional Magnetic Resonance Imaging to compare di...
The role of self-motion in acrophobia treatment
Coelho, Carlos M.; Santos, Jorge A.; Silva, Carlos; Wallis, Guy; Tichon, Jennifer; Hine, Trevor J.Acrophobia is a chronic, highly debilitating disorder preventing sufferers from engaging with high places.

Contrasting the effectiveness and efficiency of virtual reality and real enviro...
Coelho, Carlos M.; Silva, Carlos F.; Santos, Jorge A.; Tichon, Jennifer; Wallis, GuyPrevious studies reported good results in using virtual reality for the treatment of acrophobia. Similarly this paper reports the use of a virtual environment for the treatment of acrophobia. In the study, 10 subjects were exposed to three sessions of simulated heights in a virtual reality (VR) system, and 5 others were exposed to a real environment. Both groups revealed significant progress in a range of anxie...
