Learning from novel experiences is a major task of the central
nervous system. In mammals, the medial temporal lobe is crucial
for this rapid form of learning1
. The modification of synapses and
neuronal circuits through plasticity is thought to underlie memory
formation2
. The induction of synaptic plasticity is favoured by
coordinated action-potential timing acrosspopulationsofneurons3
.
Such coordinated activity of neural populations can give rise to
oscillations of different frequencies, recorded in local field poten-
tials. Brain oscillations in the theta frequency range (38Hz) are
