A screw microdrive for adjustable chronic unit recording in monkeys.
A screw microdrive is described that attaches to the grid system used for recording single neurons from brains of awake behaving monkeys. Multiple screwdrives can be mounted on a grid over a single cranial opening. This method allows many electrodes to be implanted chronically in the brain and adjusted as needed to maintain isolation. rights reserved.
متن کاملA microdrive positioning adapter for chronic single unit recording.
A new micropositioner design for use in chronic, transdural single unit recording studies is presented. The adapter is used to position an electrode microdrive assembly to any desired location within a surgically implanted recording chamber. The adapter uses a radial positioning technique that requires few moving parts. In comparison with the X-Y slide manipulator it replaces, it is more durabl...
متن کاملA new type of recording chamber with an easy-to-exchange microdrive array for chronic recordings in macaque monkeys.
In monkeys, long-term recordings with chronically implanted microelectrodes frequently suffer from a continuously decreasing probability to record single units or even small multiunit clusters. This problem is associated with two technical limitations of the available devices: first, restrictions for electrode movement, and second, absent possibility to exchange electrodes easily on a regular b...
متن کاملMiniature motorized microdrive and commutator system for chronic neural recording in small animals.
The use of chronically implanted electrodes for neural recordings in small, freely behaving animals poses several unique technical challenges. Because of the need for an extremely lightweight apparatus, chronic recording technology has been limited to manually operated microdrives, despite the advantage of motorized manipulators for positioning electrodes. Here we describe a motorized, miniatur...
متن کاملDevelopment of a miniature microdrive recording system for multisite multichannel recording from rodent brains
Introduction Assessing the electrical performance of cell populations can reveal their functions only partially. To discover the underlying mechanisms it is important to examine how they communicate with other brain regions, which can be achieved by implanting multiple recording devices to all possible cooperating areas. Multisite implantations are limited by available space in small animals, t...
