Probe Adapters

Each TDT headstage is designed for use with a particular style of probe. Probe adapters allow each headstages to be used with a wider variety of probes. When using adapters, keep in mind that standard operation (differential vs single ended) varies for acute and chronic preparations and headstages are designed accordingly. When adapting across preparations, carefully note and understand the use of the ground(G) and reference(R) connections provided on each adapter.

Acute Headstage To Chronic Probe (16 Channels)

This adapter allows the user to connect a 16-channel chronic probe (such as a TDT Omn1010 microwire array) to an acute headstage (RA16AC/RA16AC4). Standard operation for chronic preparations is single ended with ground and reference shorted together in the chronic headstage. However, the acute headstage is designed for differential operation. When using the acute headstage with our microwire arrays, short G and R together on the adapter for single ended operation.

Part number: AC-CH

Chronic Headstage To Acute Probe (16 Channels)

This adapter connects a 16-channel acute probe to a chronic headstage (RA16CH). Reference and ground are tied together by default on the chronic headstage so in general only one pin connection is necessary. A jumper is provided on the RA16Ch for differential operation. See RA16CH help for information.

Part number: CH-AC

16 Channel Acute Headstage To 32 Channel Acute Probe

This adapter connects a 32-channel acute NeuroNexus probe to two acute headstages (RA16AC/RA16AC4). Standard operation with the NeuroNexus probe is differential. If you wish to use the Reference pad on the probe, do not tie G and R together.

Part number: ACx2-NN

16 Channel Chronic Headstage To 32 Channel Acute Probe

This adaptor connects a 32-channel acute NeuroNexus probe to two chronic headstages (RA16CH). This adapter also features a holding rod for connection to a micromanipulator. As with the CH-AC adaptor, reference and ground are tied together by default on the chronic headstage so in general only one pin connection is necessary. If you wish to use the Reference pad on the probe, do not tie G and R together and cut the jumper on each headstage to make the inputs differential. See RA16CH for more information.

Part number: CHx2-NN

Note: When using these adapters with NeuroNexus probes, keep in mind that there are several versions of each of the probes. Check the NeuroNexus Website for pin diagrams. Also, see MCMap for a description and examples on how to re-map channel numbers.
