Lynx-8 Inventory Clearout Sale


Lynx-8 User Manual
The Lynx-8 amplifier has been the gold standard in electrophysiological research for over 20 years.  With advancements in technology and more demanding requirements, Neuralynx has developed the Digital Lynx SX system in order to continually raise the standards for electrophysiological research.  Neuralynx has installed over 2,000 of the L-8 amps which equates to over 16,000 channels of data acquisition with our analog systems alone. 

 
Our stock of Lynx-8 amplifiers consists of new and refurbished amps.  The refurbished amps are used but were disinfected, tested and are ready for use.  Contact sales@neuralynx.com for information regarding the Lynx 8 amplifier inventory clearout sale.

Things That Flew In Space
  • Dirt from Yankee Stadium
  • Olympic torch
  • Replica of the golden spike from the 1st Continental Railroad
  • Rocks from the top of Everest and the Moon

  • Neuralynx's Cheetah 160 (and 2 rat test subjects)




 
In 1998, Neuralynx's Cheetah 160, successfully recorded high frequency single unit “place cells” in space from two rats simultaneously on the NASA Space Shuttle. This was the first and potentially last time any neural data will be collected on a shuttle. 


July Tech Tip - Advanced Analog Reference Options
 

ERP-27 User Manual


Using a Quiet Headstage Signal as Reference
 
When all of the typical reference signals do not reduce noise to a point where your input signals are usable, you need to look elsewhere for reference selection.  If after looking at the activity of the implanted electrodes, you notice a headstage signal that seems to have no activity, you could try using this channel as a reference.  The image shown below is a typical deviation from the standard reference setup.  In the illustration shown below, A1 is the quiet channel that we wish all other channels to reference against.  The lines indicate banana plug connections while the dots indicate switch positions.  Only the A# signals from the headstage are shown with the appropriate reference selection.




 

In this configuration, all of the A# signals from the headstage will be referenced to the signal present on A1 when sent to the L8 amplifiers. The output of the L8 amplifiers will be the headstage signal minus A1, amplified. This means that there will be no amplified A1 signal, as it is referenced to itself.


Using Multiple Amplifier Settings on a Single Headstage Signal
 

The ERP-27 is hard wired to only give one output for each headstage signal. This only allows for one amplifier setting per headstage signal. If you want to record the data for a single headstage signal using multiple amplifier settings (i.e. to record a signal using narrow band filters for spikes, and wide band filters for CSC), you will need to make use of the CSC Signal Inputs. Banana wires and switch positions are denoted the same way as in the last example. Only relevant connections for the scope of this example are shown.



 


In this example, we want to record A12 as a spike channel, a narrow band CSC (to show all the data between spikes), and a wide band CSC (to show unfiltered data coming in on A12). All we have to do in order to accomplish this task is to make a banana wire with three connectors and connect the cable between A12, CSC1, and CSC2. The figure shown directly above gives the set up for this configuration. Just to show that it is possible, we are referencing CSC2 to C instead of A. As far as the ERP is concerned, anything plugged into one of the CSC inputs is a completely separate signal. The only thing you need to remember about this setup is that CSC1 and CSC2 are going to be output through JAMP4 in the back of the ERP-27, whereas A12 will be output through JAMP2. Once you have the Cheetah software setup to recognize these signals, you can set the L8 amplifiers to filter all of these signals in different ways. You can see the help file in the Cheetah software for more information on writing Cheetah configuration files.
