MULTISENSORY INTEGRATION AND PARALLEL MEMORY
SYSTEMS FOR SPATIAL COGNITION
The large body of research devoted to the neural bases of spatial memory has
unveiled the need to study numerous subfunctions including: (i) neural informa-
tion processing and coding (e.g., information storage and transmission at synapses);
(ii) multisensory integration (e.g., extraction of low-dimensional representations
from high-dimensional sensory flows; combination of multimodal signals into uni-
fied percepts); (iii) procedural memory (e.g., acquisition of low-level sensory-motor
couplings; fine tuning of coordinate movements adapted to the sensory-motor con-
text); (iv) declarative memory (e.g., elaboration of abstract descriptions of the
spatiotemporal relationships between spatial events); (v) action selection (e.g.,
reward-dependent navigation planning; dynamical weighing of multiple concurrent
strategies).
In addition to this broad functional spectrum, understanding spatial memory
requires a cross linking of different description levels including: (i) the molecular
level (e.g., dynamics of gene expression in normal and mutant organisms; dynamics
of the molecular influx through receptor channels; neuropharmacological modulation
