Introduction to NeuroLog System

Product Summary

The NeuroLog System is now widely accepted throughout the world by scientists who demand high quality, dependability and innovation in their research instrumentation.

  • Intracellular Recording
  • Extracellular Recording
  • Spike Detection
  • Electrical Stimulation
  • Pulse & Train Generation
  • Multi-channel EMG or EEG Recording
  • Pressure or other Transducer Recordings

The NeuroLogTM System is now widely accepted throughout the world by scientists who demand high quality, dependability and innovation in their research instrumentation.

Because the NeuroLogTM System is fully modular, it has the following well-recognized advantages over non-modular, multi-purpose instruments.

  • It is more flexible. Complex systems can be quickly assembled or modified.
  • It is more efficient. Modules can be shared among several set-ups, expanding capabilities without duplication. Only those modules required for a particular task are tied up and occupy rack space.
  • Fewer interface problems. Input and output levels, impedances, connectors, etc., of different modules in the system are compatible, minimizing the problems encountered in interconnecting pieces of equipment of diverse origin.
  • It is less costly. Only those modules actually required are purchased. You do not pay for all those functions added to an instrument to make it general purpose.
  • Individual modules can be added to the system at any time, as the scope and orientation of your application changes.

Each module has a split ring handle attached to its front panel. This handle serves as a cable run and as a handle for withdrawing or inserting the module into the case. All module outputs are short circuit proof. The extensive use of standard transistor-transistor logic (TTL, the standard logic in small computers) and standard linear integrated circuits ensures the lowest possible cost and highest possible compatibility with other instruments. The output levels and impedances of the linear inputs and outputs are appropriate for general purpose oscilloscopes and low gain chart recorders, etc. The NeurologTM System is also compatible with the components most frequently used in special circuitry built by individual investigators to meet their own particular needs.

Module Interconnection

The general problem of module interconnection has been minimized in the Neurolog" System by a unique method of automatic connection of outputs and inputs of neighboring modules through the case edge connectors. Thus, for many linear arrangements of modules, only the input and output cables connecting the system to the preparation and to output devices such as oscilloscopes, recorders, etc., are required. Front panel controls are therefore not obscured by cables which merely connect each module to the next. More complex module arrangements will, however, require some front panel cable interconnection; between 5 and 10 cables of various lengths will be required for a typical 13-module system. No cables are supplied with the case.


Only microminiature coaxial connectors with a snap-on action are used in the NeurologTM System, eliminating the nuisances caused by connectors such as the BNC and UHF types which have a twist-on or screw-on action. All external connections between modules are made through miniature, screened coaxial cable, which reduce cross-talk and transient pick-up, as well as eliminating the tangling of fine, unscreened wires and 1 mm (or 2 mm or 4 mm) plugs frequently used for patching in other modular systems. A variety of assembled cables, plugs, sockets, BNC to NeurologTM adapters and T type connectors are available.
