Channels 1-16 have JFETS
The ground and the stimulation channels don't have JFETS.
Ground #1 can have a JFET if needed for differential recording. (At
no extra charge.)
Note: VDD + 9v or 12v (BD25 #1) See Fig 1.

ELECTRODE ARRAY PATTERNS
Each dot represents a 50 micron wire channel and its position in the array. This is not the actual size of the array and is displayed here only as a representation.
|
For small areas. Unlike bundles, you know which wire is which channel using this design. |
2x3x3 |
|
|
For small Narrow areas. The distance between rows and individual wires can be varied to fit the need of the user. |
2x4 |
|
 |
For thin areas. Also can be cut at any angle. |
1x8 |
|
 |
For long narrow areas. Each row can be the same length or cut at different lengths or angles. |
2x8 |
