Acetylcholine has long been implicated in memory, including hippocampal-dependent memory, but the specific role for this neurotransmitter is difficult to identify in human neuropsychology. Here, we review the evidence for a mechanistic model of acety... Read More about A specific role for septohippocampal acetylcholine in memory?.

Which memory task for my mouse? A systematic review of spatial memory performance in the Tg2576 Alzheimer's mouse model (2011)
Journal Article
Stewart, S., Cacucci, F., & Lever, C. (2011). Which memory task for my mouse? A systematic review of spatial memory performance in the Tg2576 Alzheimer's mouse model. Journal of Alzheimer's Disease, 26(1), 105-126. https://doi.org/10.3233/jad-2011-101827

We review studies testing performance on tasks putatively tapping spatial memory in the Tg2576 mouse model of Alzheimer's disease (AD). This model exhibits age-dependent elevation of amyloid-β in the hippocampal formation and elsewhere in the brain.... Read More about Which memory task for my mouse?

Environmental novelty elicits a later theta phase of firing in CA1 but not subiculum (2010)
Journal Article
Lever, C., Burton, S., Jeewajee, A., Wills, T., Cacucci, F., Burgess, N., & O'Keefe, J. (2010). Environmental novelty elicits a later theta phase of firing in CA1 but not subiculum. Hippocampus, 20(2), 229-234. https://doi.org/10.1002/hipo.20671

The mechanism supporting the role of the hippocampal formation in novelty detection remains controversial. A comparator function has been variously ascribed to CA1 or subiculum, whereas the theta rhythm has been suggested to separate neural firing in...

Boundary vector cells in the subiculum of the hippocampal formation (2009)
Journal Article

“Boundary vector cells” were predicted to exist by computational models of the environmental inputs underlying the spatial firing patterns of hippocampal place cells (O'Keefe and Burgess, 1996; Burgess et al., 2000; Hartley et al., 2000). Here, we re... Read More about Boundary vector cells in the subiculum of the hippocampal formation.

Environmental novelty is signaled by reduction of the hippocampal theta frequency (2008)
Journal Article

The hippocampal formation (HF) plays a key role in novelty detection, but the mechanisms remain unknown. Novelty detection aids the encoding of new information into memory—a process thought to depend on the HF and to be modulated by the theta rhythm...
