Plexon Inc, Dallas-based maker of neurotechnology research systems, announced the sale of its 500th Multi-Channel Acquisition Processor (MAP) system since the company was founded in 1983.
DALLAS (Business Wire EON) October 20, 2008 -- The MAP system, or "Harvey Box" as it is called by many brain researchers after its inventor, Harvey Wiggins, is a modular system used for amplifying, filtering and sorting extracellular spike action potentials in real time from up to 128 microelectrodes that are implanted in the brain and nervous system. The original development work on the MAP system was funded through SBIR grants in the early 1990s from the NIH Neural Prosthesis Program under the direction of Dr. William Heetderks.
Although new methods of brain imaging such as fMRI have helped locate many functional regions in the brain, researchers require greater spatial and temporal signal resolution to reveal how brain cells encode information. Plexon's MAP system provides this high level of resolution by recording directly from individual neurons.
"The MAP system is specially designed to record and analyze signals from many individual brain cells simultaneously," said Sherman Wiebe, Ph.D., Plexon Director of Sales and Marketing. "This has driven our annual sales of the device steadily higher since its market launch in 1994."
The original system effectively spawned Plexon's growing product line, which today includes everything from electrodes and electrode microdrive positioning systems, to the preamplifiers that isolate and condition the signals, spike sorting and analysis programs, video recording and tracking systems, and other innovations for neurophysiology research.
"A passion for neuroscience research, innovative product development, and dedicated customer support are important reasons for Plexon's longevity and wides
