The Morris water maze (MWM) was described 20 years ago as a device to investigate
spatial learning and memory in laboratory rats. In the meanwhile, it has become one of the …

Identifying the scope and nature of memory processing by the hippocampus has proved a
formidable challenge. The major initial insights came from studies of amnesia in human …

Abstract Low-Frequency Oscillations (LFO) in the range of 7–9 Hz, or theta rhythm, has been
recorded in rodents ambulating in the real world. However, intra-hippocampus EEG …

Aging is associated with specific impairments of learning and memory, some of which are
similar to those caused by hippocampal damage. Studies of the effects of aging on …

Hippocampal pyramidal cells are called place cells because each cell tends to fire only
when the animal is in a particular part of the environment—the cell's firing field. Acute …

In contrast to sensory cortical areas of the brain, the relevant physiological inputs to the
hippocampus, leading to selective activation of pyramidal cells, are largely unknown …

Although so-called “naive” Bayesian classification makes the unrealistic assumption that the
values of the attributes of an example are independent given the class of the example, this …

Hippocampus place cell discharge is an important model system for understanding
cognition, but evidence is missing that the place code is under the kind of dynamic …

The ability to accurately recall locations and navigate our environment relies on multiple
cognitive mechanisms. The behavioural and neural correlates of spatial navigation have …

This experiment investigated the involvement of the dorsal hippocampal CA3-region in the
different phases of learning and memory in spatial and non-spatial tasks. To do so, we …
