Abstract
We propose a computational model which is con-
sistent with several neurophysiological findings con-
cerning biological head-direction cells and hippocam-
pal place cells. The model consists of two separate
neural systems providing directional and place cod-
ing representations, respectively. These two modules
are strongly coupled and interact with each other to
form a unitary spatial learning system. We stress the
importance of correlating idiothetic and allothetic sig-
nals to determine the dynamics of the system in order
to stabilize head-direction and place representations
over time. We give experimental results obtained by
