Visual Psychophysics and Neuroimaging Laboratory

We are interested in the process of interpreting, analyzing and representing visual information in the brain. Research topics include visual impairment, visual crowding, reading, organization of the visual cortex and cortical plasticity. Our research involves different methodologies: psychophysics, functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI).

Project Title: Visual crowding
Our ability to perceive off-gaze objects is greatly affected by the presence of distractors due to visual crowding. Here we want to study the mechanisms behind crowding.

Project Title: Effects of age in depression
Is depression in young adults the same as depression in older people? Here we want to study the effects of age on the neural correlates of depression.

Project Title: Gender differences in cognitive abilities
How different (or similar) are the two genders on different cognitive abilities? Here we want to start by addressing the question of whether girls are really better than boys in language ability.

Intern Selection (for all projects):
Strong work ethics
High motivation for research
Academic excellence
Good language skills
