Examining local network processing using multi-contact laminar electrode recording.
Cortical layers are ubiquitous structures throughout neocortex that consist of highly recurrent local networks. In recent years, significant progress has been made in our understanding of differences in response properties of neurons in different cortical layers, yet there is still a great deal left to learn about whether and how neuronal populations encode information in a laminar-specific man...
متن کاملComprehensive chronic laminar single-unit, multi-unit, and local field potential recording performance with planar single shank electrode arrays.
BACKGROUND Intracortical electrode arrays that can record extracellular action potentials from small, targeted groups of neurons are critical for basic neuroscience research and emerging clinical applications. In general, these electrode devices suffer from reliability and variability issues, which have led to comparative studies of existing and emerging electrode designs to optimize performanc...
متن کاملSelective Fascicular Recording of the Hypoglossal Nerve Using a Multi- Contact Nerve Cuff Electrode
The use of nerve cuff electrodes as p a r t of a closed loop functional electrical stimulation (FES) system has been demonstrated as a reliable alternative to artificial sensors (e.g., strain gauge). T o circumvent the need for multiple electrodes to record neural activity f rom different fascicles within a nerve, the flat interface nerve electrode (FINE) is presented as a potential approach to...
متن کاملVelocity-selective Recording using Multi-electrode Nerve Cuffs
A technique to improve the signal-to-noise ratio of recordings from cuff electrodes is presented. It is also shown that the system is inherently velocity selective. Unlike competing methods, the use of the system as a practical velocity-selective filter requires only relatively simple signal processing. This is due to the intrinsic properties of the multi-electrode cuff system.
متن کاملOverground locomotion in intact rats: contact electrode recording.
The aim of the experiments was to check the validity of the method of contact electrodes for studying overground locomotion in the rat. The basic indices of locomotion, obtained in 7 intact rats with at least 100 steps recorded in each, were analysed and compared with those described by other authors using different methods of movement recording. It was found that the method of contact electrod...
