Definitions of technical terms
ASIC: Integrated circuit that contains recording electrodes, amplifiers, multiplexers and
•
digitizers.
Probe Shank: Implanted part of the probe ASIC (Figure 3).
•
Probe Base: Non-implanted part of the probe ASIC (Figure 3).
•
Flex: Flexible PCB (or FPC) onto which the probe ASIC and additional passive and active
•
components are mounted (Figure 3). It connects to the HS.
Control System: System components required to enable control of and data streaming from
•
Neuropixels probes. These entail the headstage, interface cable and PXIe acquisition module.
Headstage: Miniature board that enables reliable power supply to the probe and is essential for
•
bi-directional data communication from/to the probe (Figure 7).
Headstage Test Dongle: a small test box (Figure 10) that plugs into the ZIF connector of a
•
headstage. Its purpose is to help verify the functionality of a Headstage.
Interface Cable: Thin and flexible cable for power and bidirectional data transmission between
•
HS and PXIe acquisition module (Figure 8).
PXIe Acquisition Module: Custom-made PCB module with two FPGAs for probe configuration,
•
data acquisition and transmission to PC via PCIe interface (Figure 9).
Port: USB-C plug on the front panel of the PXIe acquisition module. Each front panel contains
•
4 ports (Figure 9) allowing connection of up to 4 interface cables.
PXIe Chassis: Houses PXIe modules and connects them with a high-performance backplane that
•
offers timing and synchronization capabilities.
Driver: The software files that need to be installed on the host PC to enable communication
•
with the Neuropixels control system and to develop custom application software.
