Results from recent studies of retrograde amnesia following damage to the hippocampal
complex of human and non-human subjects have shown that retrograde amnesia is …

A fundamental question in memory research is how our brains can form enduring memories.
In humans, memories of everyday life depend initially on the medial temporal lobe system …

We recorded from single neurons in the hippocampus and entorhinal cortex (EC) of rats to
investigate the role of these structures in navigation and memory representation. Our results …

Background Episodic memories are encoded within hippocampal and neocortical circuits.
Retrieving these memories is assumed to involve reactivation of neural ensembles that were …

Neuronal immediate-early gene (IEG) expression is regulated by synaptic activity and plays
an important role in the neuroplastic mechanisms critical to memory consolidation. IEGs can …

Electrolytic lesions of the dorsal hippocampus (DH) produce deficits in both the acquisition
and expression of conditional fear to contextual stimuli in rats. To assess whether damage to …

We have shown previously that electrolytic lesions of the dorsal hippocampus (DH) produce
a severe deficit in contextual fear if made 1 d, but not 28 d, after fear conditioning. As such …

Dorsal hippocampal (DH) lesions produce a severe deficit in recently, but not remotely,
acquired contextual fear without impairing memory of discrete training stimuli, ie, DH lesions …

This series of studies investigated the effects of predator exposure on working memory in
rats trained on the radial arm water maze (RAWM). The RAWM is a modified Morris water …
