NeuroLog System
Compact and versatile; our modular electrophysiology workstation – the NeuroLog System – is now widely accepted throughout the world by leading scientists, researchers and practitioners alike.
As a fully modular device, it’s suitable for a diverse range of roles, including amplification, intracellular and extracellular recording, pulse and train generation, spike detection, electrical stimulation, multi-channel isolated EMG and EEG recording, pressure or other transducer recordings and more. And it can offer many advantages over other non-modular instruments.
For example, Digitimer’s NeuroLog System provides:
- greater flexibility – a complex system can be quickly devised by assembling and modifying various modules
- enhanced efficiency – only the modules that are required for a particular task need to be tied up and occupy rack space. Modules can be shared amongst several set-ups, and can be easily swapped and changed, expanding the capability of the NeuroLog System without causing duplication.
- wider compatibility – all of the input and output levels, impedances, and connectors etc. of the different modules are compatible. As such, pieces of equipment can be interconnected in the NeuroLog System, without causing any problems – even if those pieces are of diverse origin.
- cost-effective – only required modules need to be purchased. You won’t have to pay for unnecessary functions or buy a ‘general purpose’ system. Individual modules can simply be added to the system at any time, as the scope and orientation of your application changes.
We currently offer two NeuroLog system cases. The first (and most popular) includes the NL900D Case and Power Supply Unit. This allows up to 13 modules to be installed at any one time. Alternatively, we also offer the NL905 – which is slightly smaller and holds up to 4 modules in total.
Either way, they can both be used to monitor several different parameters at once, and are a great option for scientists who demand quality, dependability and innovation in their research instrumentation.
FAQs
What can the NeuroLog System be used for?
Thanks to its modular nature, the NeuroLog System can be used for a diverse range of applications. These applications fall broadly into four categories, including signal amplification, triggering and pulse generation, signal conditioning, filtering and processing, and electrical stimulation.
Advice on the best modules to use for each of these categories can be found in our ‘NeuroLog System Application Notes’ guide. Here you’ll find the categories broken down into more specific applications, with information on the modules typically used for each. But if you’re still struggling to identify the best options for your requirements, please feel free to contact us at any time.
Do modules for the NeuroLog System need to be purchased separately?
Yes. Individual modules will need to be purchased separately, along with a NeuroLog Case and Power Supply Unit and possibly interconnection and output cables or cable adaptors too.
But this is one of the main advantages of our NeuroLog System. There’s no need to spend more than necessary on a ‘general purpose’ workstation – with functions that you don’t require. You can simply create a system that meets your needs exactly, and add to it as the scope of your work changes.
How much does the NeuroLog System cost?
This will depend on several factors, including whether you need the 13-module or 4-module case, the number of modules required, and the type of modules needed for your specific application.
Guide prices for all products can be found on site. However, for a more accurate idea of how much your NeuroLog System will cost, the best option is to get in touch or complete our quote request form. A member of the team will then review the full list of equipment that you require and get back to you with a price – either via email or telephone call, depending on your preferences.

AD Interface Modules
These modules accept an analogue signal, which is converted into digital outputs. The NL601 has a digital counter which produces an analogue output proportional to the count, while the NL201 is an amplitude/window discriminator used for detection of neuronal action potentials (spikes), during electrophysiological recording.Subcategories / ProductsAmplifier Modules
NeuroLog System includes a range of amplifier modules designed for a variety of electrophysiological recording applications. Our amplifiers are suitable for intracellular (NL102G), extracellular microelectrode and gross electrode recordings (NL100AK/NL104A), as well as isolated multi-channel EEG/EMG (NL844/NL820A). The range also includes bridge amplifiers for force (NL109) and pressure measurements (NL108A).Subcategories / ProductsAnalogue Modules
The NL254 Instantaneous Ratemeter provides two ranges for both pulses per second (pps) and pulses per minute (ppm), with the rate displayed on a 3 digit display as 000-999 or 00.0 to 99.9 and an analogue voltage output is provided which is proportional to the instantaneous rate. The NL506 contains a single pole change-over analogue switch. The state of which is controlled by a logic signal. The NL703 was designed to produce an analogue signal which represents the strength of muscle activity. It is commonly used with our NL844/NL820A for isolated EMG recording.Subcategories / ProductsDigital Modules
The digitally controlled NL405 Width/Delay and NL603 Counter are commonly used to add complexity to pulse timing protocols and can also be used to extend or count TTL inputs. Other modules in this category, such as the NL501 Logic Gate can be used for more demanding signal processing where multiple inputs control an output process.Subcategories / ProductsFilter & Conditioner Modules
Our range of single and multi-channel filters and signal conditioning modules have been designed to allow precise identification of signals of interest against a background of unrelated frequencies. The NL125/6 Band-pass Filter features variable high and low cut settings and a 50/60Hz notch filter. The NL125/6 is commonly used with the NL100AK/NL104A or our NL102G amplifiers for extracellular and intracellular recording. Our four channel filters are intended for use with our NL844/NL820A isolated amplifier in EEG and EMG applications. Other modules in this category, such as the NL143 Difference Amplifier have been developed for a range of more specialist roles.Subcategories / ProductsGenerator Modules
The NL301 Pulse Generator and NL304 Period Generator provide the "clocks" of the NeuroLog System and allow users to setup stimulus timing protocols of variable complexity. With the addition of other modules, it is possible to develop protocols that consist of repeating bursts or trains that can continue indefinitely or stop after a certain period of time or number of pulses. Our NL412 Pulse unit provides a simple hand-held trigger to initiate stimulation sequences.Subcategories / ProductsNeurolog Accessories
The NeuroLog System uses the Swiss-made Lemo brand of microminiature coaxial connector and cables for module interconnection and output. These connectors are highly-regarded in a variety of industries due to their robust construction and ease of use. Digitimer provides a vast array of plugs, sockets, cables, adaptors and accessory kits, which may be used with our existing NeuroLog System products or incoporated into your own custom modules.Subcategories / ProductsNeurolog System Cases
At the heart of the NeuroLog System is the NL905 or NL900D Case and Power Supply Unit. These cases not only house and power the various modules, but they also provide a cable free communication between modules. This not only reduces costs, but also keeps the front panel controls free of tangled wires. The NL905 is a compact bench-top unit that can hold up to 4 modules, while the NL900D is a 19" rack or bench-mountable alternative that accommodates up to 13 modules. Each can be supplied with blank panels to cover unused slots.Subcategories / ProductsPressure/Force Transducers & Accelerometers
Digitimer offers a selection of pressure and force transducers which are compatible with our NL108A Pressure and NL109 Bridge Amplifiers. We also offer the NL260/263 3-axis accelerometer system for vibration/tremor measurement.Subcategories / ProductsStimulator Modules
The NeuroLog System includes the NL800A, a compact, constant current, linear stimulus isolator. The NL800A can output currents from 0-10mA in four ranges via an analogue voltage input. Our NL510A Pulse Buffer and NL512 Biphasic Pulse Buffer provide interfaces between a control signal and the NL800A, allowing for the generation of amplitude adjustable, monophasic or biphasic constant current stimuli.Subcategories / Products
