In human neuroscience, studies of cognition are rarely grounded in non-task-
evoked,'spontaneous' neural activity. Indeed, studies of spontaneous activity tend to focus …

We report that temporal spike sequences from hippocampal place neurons of rats on an
elevated track recurred in reverse order at the end of a run, but in forward order in …

Some theories of memory propose that the hippocampus integrates the individual items and
events of experience within a contextual or spatial framework. The hippocampus receives …

Memory consolidation is thought to depend on the reactivation of waking hippocampal firing
patterns during sleep. Following goal learning, the reactivation of place cell firing can …

Mammalian brains exhibit population oscillations, the structures of which vary in time and
space according to behavioural state. A proposed function of these oscillations is to control …

Neural-network oscillations at distinct frequencies have been implicated in the encoding,
consolidation and retrieval of information in the hippocampus. Some GABA (γ-aminobutyric …

Neural ensembles were recorded from the CA3 region of rats running on T-based decision
tasks. Examination of neural representations of space at fast time scales revealed a transient …

Sensory cue inputs and memory-related internal brain activities govern the firing of
hippocampal neurons, but which specific firing patterns are induced by either of the two …

Neural stem cells in various regions of the vertebrate brain continuously generate neurons
throughout life,,,. In the mammalian hippocampus, a region important for spatial and …

Electrophysiological recordings in animals, including humans, are modulated by oscillatory
activities in several frequency bands. Little is known about how oscillations in various …
