Information processing in space-time by the hippocampus

Processing of tactile information by the hippocampus.

The ability to detect unusual events occurring in the environment is essential for survival. Several studies have pointed to the hippocampus as a key brain structure in novelty detection, a claim substantiated by its wide access to sensory information through the entorhinal cortex and also distinct aspects of its intrinsic circuitry. Novelty detection is implemented by an associative match-mism...

Time and space in the hippocampus.

It has been hypothesized that one of the functions of the hippocampus is to enable the learning of relationships between different stimuli experienced in the environment. These relationships might be spatial ("the bathroom is about 5m down the hall from the bedroom") or temporal ("the coffee is ready about 3 min after the button was pressed"). Critically, these spatial and temporal relationship...

Dynamical Information Processing in the CA1 Microcircuit of the Hippocampus

A major challenge to understanding cortical function is the complexity found both at the single cell and microcircuit levels. Here we outline what is known about the microcircuitry of the CA1 region of the mammalian hippocampus. We then explore the possible functional roles of the variety of neuronal types within this microcircuit during dynamic information processing. This is considered within...

Ii Time-space Processing

We are concerned with time space signal processing in CDMA system, which uses specific receiving configuration with RAKE receivers. This configuration is improving the system performances while decreasing the system capacity. Antenna array could provide capacity improvement while keeping the good performances from time processing. Actually this is conventional time space signal processing perfo...
