APC  Neural Spike Recording System

The Acquisition Processor Channel (APC) performs signal conditioning, spike discrimination, and data recording in a multi-channel configuration.  Users benefit from:

  • Continuously adjustable digital filtering and gain.

  • Remote retrieval of data and insertion of digital messages into the recorded data file provided by built-in TCP/IP data server

  • Ability to record waveforms, timestamps, and event data in several file formats for use with available standard analysis software.

 

 

 

Two recording modes

Spikes

High sampling rate for waveform recording.

Continuous

Slow sampling rate for field potential or behavioral variable recording.

Integrated artifact suppression

Line Noise

Builds replica of artifacts from periodic signals (such as 50/60Hz line noise) and removes it from the original signal. Requires use of LSG.

Stimulus Artifact

Builds replica of artifacts from aperiodic signals (such as micro stimulation pulse).  No additional hardware needed.

 
  

Three preprogrammed modes of neural spike discrimination:

Slope/Height Window Discrimination

Discriminates any waveform that passes through a user-defined time/amplitude window.

Adaptive Template Matching

Discriminates waveforms from up to four user defined waveform template shapes. Templates can be set to adapt to changes in waveform shape based upon user-defined criteria.

Principal Component Analysis

Discriminates waveforms based upon the results of the principal component method of analysis.

APM Single-Channel

Neural Spike Discriminator

The Acquisition Processor Module (APM) features all of the APC functionality in a stand-alone module for single channel applications.

  • Replaces conventional window discriminators and amplifiers when used with the Single Channel Preamp (SCP) System

  • Easily integrates into existing systems.
