Extracellular 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 کاملPrinciples of Extracellular Single-Unit Recording
8 There is a rather large gap between membrane properties of individual neurons and behavior or physiological events. To bridge this gap, we need to be able to understand the activity of individual neurons and how that activity contributes to neuronal circuits. Extracellular microelectrode recording, which focuses on neuronal action potentials of individual neurons as the “code” used by the int...
متن کاملAn olfactory bulb slice-based biosensor for multi-site extracellular recording of neural networks.
Multi-site recording is the important component for studies of the neural networks. In order to investigate the electrophysiological properties of the olfactory bulb neural networks, we developed a novel slice-based biosensor for synchronous measurement with multi-sites. In the present study, the horizontal olfactory bulb slices with legible layered structures were prepared as the sensing eleme...
متن کاملAn evaluation of photoengraved microelectrodes for extracellular single-unit recording.
Microelectrodes fabricated using integrated-circuit technology are shown to be suitable for extracellular single-unit recording, and the factors influencing electrode-cell coupling are discussed. Electrode tip size as well as location is found to be critical in recording high spike amplitudes, suggesting that the paths for current flow in central nervous system (CNS) tissue may be extremely small.
متن کاملExtracellular Recording of Light Responses from Optic Nerve Fibers and the Caudal Photoreceptor in the Crayfish.
Few laboratory exercises have been developed using the crayfish as a model for teaching how neural processing is done by sensory organs that detect light stimuli. This article describes the dissection procedures and methods for conducting extracellular recording from light responses of both the optic nerve fibers found in the animal's eyestalk and from the caudal photoreceptor located in the ve...
