A body-part map in the occipito-temporal cortex: One of the most robust organizational principles in the brain is the topographic mapping of a human body in the somatosensory and motor cortices. Human fMRI and patient studies have shown that some higher-order visual areas are selectively involved in the visual perception of ourselves and other people's appearance. Do these areas represent information regarding a human body in an orderly map? If so what can be organizing principles of this body-part topography? May action-related information converge with this visual map? Tanya  Orlov, Tamar Makin, learn more

Visual perception, memory & eye movements:  Our brain constantly generates a stable and seemingly complete representation of the visual scene in spite of the fact that the visual image is heavily blurred in the periphery (see demo) and is constantly changing due to our eye movements. How do we achieve this? Ayelet McKyton, Yoni Pertzov, Learn more

Hand-position space: Our ability to interact with the external environment critically depends on the brain’s computing of relative spatial locations of objects with respect to the hands, each thought to be coded in a separate set of reference frames. How does the brain achieve the complex interactions between vision, haptics & proprioception? What happens to this multisensory integration when the hand is amputated? Tamar MakinLearn more

Visuomotor interactions: During daily life, we reach and grasp objects located in a variety of positions in our visual-field. Where is the information regarding the visual (position) and motor (acting-hand) aspects integrated in the brain? Michal Eisenberg, Alit Stark, Lior Shmuelof

Action observation: The mirror-system hypothesis suggests that primates perceive and interpret others' actions by generating an an internal motor representation (e.g., simulation). Will the observation of others' actions interfere with our own motor execution? Lior Shmuelof

Numerical & ordinal position judgments : The recall of a list of items in a serial order is a basic cognitive skill. However, it is unknown whether a list of arbitrary items is remembered by associations between sequential items or by associations between each item and its ordinal position. What are the mechanisms underlying serial order memory? Tanya Orlov

Plasticity in the visual cortex following blindness: Perceiving the world in total absence of vision must often be based on verbal descriptions of events and their spatial relationships (for instance, following a basketball game on the radio). Congenitally blind people are therefore likely to depend more on memory in general, and on verbal memory in particular, to interact with the world.
