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

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

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

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

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. |
