System Eckhorn Microdrive

The multielectrode manipulator “System Eckhorn” was developed in the laboratory of Prof. Dr. R. Eckhorn at the Department of Neurophysics, Philipps-University Marburg, Germany and successfully used for parallel independent insertion of fiber microelectrodes through the intact dura into the brain of chronically prepared cats and monkeys

Key features:

Axial resolution better than 1μm, x-y-Positioning with a grid and special holder
Patented rubber-tube drive, no hysteresis, slick or free motion due to patented rubber tube drive (avoids drawbacks of cable, direct or hydraulic driven systems)
Electrode travel range up to 35.000μm
Variable speed range from 0…250μm/s, higher velocity on request
7- and 16- channel Version available
28 or 64 channel Tetrode Versions available
49 or 112 channel Heptode Versions available
No electrode connection cables free in air! Complete metal shield around all microelectrodes
Suitable for cortical and deep brain recordings
Very close electrode spacing available (down to 80μm)
Different electrode arrangements available (linear, concentric, etc.)
Integrated low noise preamplifiers
