Electrophysiology


Landisman Lab: Image of a custom patch rig designed to provide easy access to a mechanically stable preparation.


Landisman Lab: Sliding objective mount and computer controlled focus allow for simplified magnification changes when recording electrodes are in place.


Landisman Lab: Straightforward software routines to simplify analysis.


Meister Lab: The device shown was built by the Litke lab at UCSC. Carried by a behaving rodent, it is capable of amplifying, conditioning, and multiplexing data from approximately 80 electrodes. We have assisted the Meister Lab as they incorporate this device into their research toolkit.


Meister Lab: The Meister lab wanted to wireless transmit data recorded with the Litke device. We characterized the transmission properties of multiple miniature tranmitters in order to faithfully reconstruct the neural signal.


Meister Lab: Tobi Sutz is using one of a collection of programs created to record and visualize 64 channels of electrophysiological data. This particular program works with a wired version of the Litke device.


Meister Lab: Another view of the recording software organized to allow for the separation of spike waveforms recorded on tetrodes

Meister/Dulac/Kreiman Labs: Intan Technology produces a commercially available 16 channel amplifier that functions similar to the Litke chip. We are helping to integrate this chip into research equipment for multiple labs. The P.C.B. shown was made by Joe Bergan of the Dulac lab.

Dowling Lab: A simple rig used to record extracellularly from larval zebra fish retina.


Dowling Lab: A small, high resolution L.C.D. screen use to present stimuli to larval zebra fish.


Meister Lab: A custom open frame stereotatic device.

Engert Lab: Head stage adaptors required for extended reach and clearance.


Schier Lab: Driver for a rapid-response temperature controlled microscope stage instert. The unit is capable of changing temperature at a rate of 2 degrees C/s.

Schier Lab: Temperature controlled micrsocpe stage instert. Perfusion inflow, outlet and tempearture probes are visible. Insert accomadates standard plastic dishes.

Electrophysiological tools give us a direct measure of neural function. We have extensive experience recording from neurons intra/extra-cellularly. We have designed a variety of amplifiers, signal conditioners, data acquisition software and data analysis programs.
