differences between musicians and non-musicians.
1045.2 Spatially and temporally distributed representations of faces, J. Haxby, Green Hall
Princeton University, Princeton, NJ, USA
The neural representation of faces is distributed in space and time. Locally distributed
representations of faces and other objects are found in ventral and lateral temporal cortex.
Whereas the ventral temporal representation carries information about face identity, the lateral
temporal representation carries information about how faces change with movement. The activity
evoked by faces also extends across other cortical areas, reflecting activation of additional
information, such as the direction of attention indicated by gaze direction. Neural responses to
faces are also distributed in time, reflecting a differentiation between early feed-forward
processing and later processing that is influenced by inter-regional interactions.

Slow waves of the EEG show that storage and retrieval of long-term memory (LTM) contents
produce a material-specific topography which is by and large the same as when similar contents
have to be manipulated in working memory (WM). Moreover, in both cases, the maximum
amplitude of each slow wave pattern increases with increasing task demands. In sum, these studies
not only prove a distinct topography for different representations but also that each topography is
specifically modulated by the task demands. The congruent topography strongly supports the idea
that WM and LTM contents are activated within the same cortical areas.
1045.4 Associative learning signals in the medial temporal lobe, W.A. Suzuki, New York
University, New York, NY, USA
To examine the patterns of neural activity during associative memory formation, we trained two
monkeys to perform a location-scene association task. The activity of individual hippocampal
neurons was recorded as monkeys learned which one of four identical targets superimposed on a
complex visual scene was associated with reward (Wirth et al., 2003). Hippocampal neurons
signaled new learning with dramatic changes in their stimulus-selective response properties. This
changing neural activity was significantly correlated with the animal’s behavioral learning curve.
We call these cells “changing” cells. These findings provide new insights into how associative
learning is represented within the medial temporal lobe.

Blind and sighted adults were compared in short- and long-term memory tasks to test if and if yes
which memory functions are capable to adapt to specific requirements. We found higher
short-term and long-term memory in the congenitally blind than in the sighted. Behavioral and
ERP results showed that blind people encode auditory verbal material more efficiently than
matched sighted controls and that this in turn allows them to recognize theses items with a higher
