The global record of memory in hippocampal neuronal activity

Article Abstract:

The hippocampal area of the brain in humans is essential for declarative or episodic memory, but there is controversy over whether the hippocampus mediates similar general memory functions in other species. Rats were trained to perform recognition memory tasks and it was found that hippocampal neuron activity was consistently linked to perceptual, behavioural or cognitive events, regardless of the location of the events, suggesting that non-spatial events are fundamental to hippocampal representation.

The LTP-memory connection

Article Abstract:

A high-frequency electrical stimulation of the thalamus-to-amygdala route activates the long-term potentiation (LTP). This in turn increases the synaptic responses to natural auditory stimulation. The LTP involves the multiple memory systems and loci, but not the hippocampus or spatial memory. The hippocampal N-methyl-D-aspartate receptors are used for analyzing a spatial strategy or may act in different brain circuits.

Recollection-like memory retrieval in rats is dependent on the hippocampus

Article Abstract:

Few techniques are adapted to examine odour recognition memory in rats to determine whether animals employ multiple processes in recognition memory and to explore the anatomical basis if this distinction. A recognition memory task is designed to exploit rat's superb memory capacity for odours.
