Memory processes and related disease states   In other studies,
neural network models have been used to understand how
synchronous activity spreads through a population of neurons
during epilepsy. These studies can help to shed light on the
complex neural dynamics underpinning epileptic seizures, and may
help to guide the discovery of effective drugs.    Case study A
unified account of spatial and episodic memories in the brain
Medial temporal lobe structures including the hippocampus are
implicated in both episodic memory and spatial function. Our
research has shown that a single attractor neural network model
can store both the discrete memories that characterise episodic
memory and the continuous representations that characterise
physical space (Rolls, E.T., Stringer, S.M. and Trappenberg,T.P.
(2002). Proc. R. Soc. Lond. B 269: 1087-1093). Combining both
types of representation in a single network is necessary if
objects and where they are located in space must be stored.  The
