Other Equipment
Miniaturized VLSI Preamplifier Systems
The Department of Electrical Engineering of the Southern Methodist
University, Dallas, with assistance from the CNNS has developed
a compact, stable, 64 channel preamplifier system using VLSI
technology. The circuits have an amplification factor of
x50, achieve very low noise, and have remarkably short input
saturation after a large stimulation pulse. A laptop computer
allows the selection of any combination of channels for stimulation
with as many as 4 separate inputs patterns This equipment
can be obtained from SMU. (Dr. Lorn Howard: (214) 768-3022
or Dr. Milton Gosney (214) 768-3115; FAX: (214) 768-3085.

Computerized Multichannel Real-time Data
Acquisition
and Processing System
A multichannel second stage amplifier system with computer
control of channel selection and assignment, data acquisition
modes, and data processing software can be obtained from Plexon
Inc., Dallas (formerly Spectrum Scientific). This
powerful system has 4 input channels assigned to one digital
signal processor and allows parallel 64 (or more) channel processing
in real time. Compatible with conventional or the SMU-VLSI
preamplifiers and usable for both cell culture and animal multichannel
extracellular recording. Please contact Harvey
Wiggins at Plexon for further information.
