Hippocampus: Mapping or memory?
The identification of 'place cells' in the hippocampus has suggested a special role for this brain structure in spatial mapping, but other studies have indicated a more general role in memory. New findings on place cells point the way towards a reconciliation of the mapping and memory views.
متن کاملThe human hippocampus: cognitive maps or relational memory?
The hippocampus is widely accepted to play a pivotal role in memory. Two influential theories offer competing accounts of its fundamental operating mechanism. The cognitive map theory posits a special role in mapping large-scale space, whereas the relational theory argues it supports amodal relational processing. Here, we pit the two theories against each other using a novel paradigm in which t...

and more recently in animals as well (Eichenbaum, 1997). Furthermore, several recent electrophysiological McGill University Montreal PQH3A 1B1 studies have revealed properties of hippocampal neu-ronal firing patterns that are inconsistent with the notion Canada ‡ Department of Neuroscience and Neurology of a cognitive map and indicate a broader scope of information processing. This paper will f...
متن کاملComparison of Memory Impairment and Oxidative Stress Following Single or Repeated Doses Administration of Scopolamine in Rat Hippocampus
Introduction: Scopolamine, a muscarinic cholinergic receptor antagonist, is widely used to induce memory impairment in experimental animals. The present study aims to compare memory impairment and oxidative stress following single and repeated doses administration of scopolamine. Methods: A group of rats received a single shot of scopolamine in different doses (0.5, 1, or 3 mg/kg, IP) 24 hours...
متن کاملThe role of the hippocampus in long-term memory: is it memory store or comparator?
Several attempts have been made to reconcile a number of rival theories on the role of the hippocampus in long-term memory. Those attempts fail to explain the basic effects of the theories from the same point of view. We are reviewing the four major theories, and shall demonstrate, with the use of mathematical models of attention and memory, that only one theory is capable of reconciling all of...
