Hippocampal Signatures of Episodic Memory: Evidence from Single-Unit Recording Studies
What hippocampal neural firing patterns signal memory and, more importantly, how is this memory code used by associated structures to translate a memory into a decision or action? Candidate hippocampal activity patterns will be discussed including (1) trajectory-specific firing of place cells with place fields on an overlapping segment of two (or more) distinct trajectories (2) prospective firi...
متن کاملExtracellular Single-Unit Recording Methods*
Since their refinement in the early 195Os, extracellular, singleunit recording methods have been used to obtain a wealth of data about the properties of CNS structures. The applications of the technique have been diverse: extracellular microelectrodes have been used to map the potential fields of single discharging neurons in order to answer fundamental questions about the excitability of CNS d...
متن کاملHippocampal place cells, context, and episodic memory.
Although most observers agree that the hippocampus has a critical role in learning and memory, there remains considerable debate about the precise functional contribution of the hippocampus to these processes. Two of the most influential accounts hold that the primary function of the hippocampus is to generate cognitive maps and to mediate episodic memory processes. The well-documented spatial ...
متن کاملPlacing hippocampal single-unit studies in a historical context.
A profound increase in the study of the role of the hippocampus in behavior and cognitive processing resulted from the startling discovery by O'Keefe and Dostrovsky in 1971 that hippocampal neurons fire selectively in different regions or "place fields" of an environment. That discovery spawned a comprehensive theory of hippocampal function that was elucidated in the publication, The Hippocampu...
متن کاملA new method for acquisition and analysis of single unit recording data
Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...
