The NeuroLog System, a portable and adaptable modular electrophysiological workstation, is currently widely used by eminent researchers, practitioners, and scientists around the globe.
It is suitable for a wide variety of roles as a fully modular device, 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. Additionally, it has a lot of benefits over instruments that aren't modular.
For instance, the NeuroLog System from Digitimer offers:
- more versatility — by assembling and customizing different parts, a sophisticated system may be easily created.
- heightened efficiency — just the modules necessary for a specific job need to be tethered and take up rack space. The NeuroLog System can be expanded without duplication by using modules that can be shared among various setups and that are simple to switch out and update.
- greater compatibility — all of the input and output levels, impedances, connections, and other characteristics of the various modules are compatible. As a result, even if the components of the equipment are of different origins, they can still be connected in the NeuroLog System without encountering any issues.
- cost-effective — because only necessary modules must be bought. You won't have to pay for extra features or get a system that is "general purpose." As the scope and orientation of your application evolve, specific modules can be added to the system as necessary.
There are two NeuroLog system cases available right now. The NL900D Case and Power Supply Unit are included in the first (and most popular) group. 13 modules can now be added at once thanks to this. As an alternative, we also provide the NL905, which is a little bit smaller and can accommodate up to 4 modules altogether.
In either case, they are both excellent choices for scientists that expect excellence, dependability, and creativity in their research instrumentation and may both be used to simultaneously monitor a number of distinct parameters.
FAQs
What purposes may the NeuroLog System serve?
The NeuroLog System may be utilized for a wide variety of applications because of its modular design. These applications can be broadly divided into four categories: electrical stimulation, signal conditioning, filtering and processing, signal amplification, triggering and pulse creation.
In "NeuroLog System Application Notes" manual, the manufacturer provides recommendations on the most appropriate modules to employ for each of these categories. You can find information on the modules generally used for each of the categories' more particular applications in this manual. However, if you're still having trouble choosing the finest solutions for your needs, don't hesitate to get in touch with us at any time.
Do separate modules for the NeuroLog System have to be purchased?
Yes. Individual modules, a NeuroLog Case, a Power Supply Unit, and optionally connectivity and output cables or cable adaptors are all separate purchases that must be made.
But one of the key benefits of NeuroLog System is this. Spending more money than necessary on a "general purpose" workstation with features you don't need is unnecessary. Simply design a system that perfectly satisfies your requirements, then add to it as the nature of your work evolves.
What is the price of the NeuroLog System?
This will rely on a variety of elements, such as whether you want the 13-module or 4-module situation, how many modules you need, and the kind of modules you require for your particular application.
On the website of manufacturer, there are guide pricing for every product. However, the best course of action is to get in touch or fill out estimate request form to obtain a more precise sense of how much your NeuroLog System would cost. Depending on your choices, a team member will next analyze the entire list of equipment you need and get back to you with a pricing through email or phone call.
AD Interface Modules
An analog signal is accepted by these modules, and it is turned into digital outputs. In contrast to the NL201, which is an amplitude/window discriminator used for the identification of neural action potentials (spikes) during electrophysiological recording, the NL601 contains a digital counter that generates an analog output proportionate to the count.

- NL201 Spike Trigger
Amplifier Modules
A number of amplifier modules are part of the NeuroLog System, which is intended for use in a range of electrophysiological recording applications. Our amplifiers can be used for isolated multi-channel EEG/EMG recordings (NL844/NL820A), intracellular (NL102G), extracellular microelectrode and gross electrode recordings, and so forth. Bridge amplifiers for force (NL109) and pressure measurements (NL108A) are also part of the spectrum.

Analogue Modules
The NL254 Instantaneous Ratemeter has two ranges for both pulses per second (pps) and pulses per minute (ppm). The rate is displayed as 000-999 or 00.0 to 99.9 on a 3-digit display, and a proportional analogue voltage output is also offered. A single pole change-over analogue switch is present in the NL506. Its status is managed by a logic signal. The NL703 was made to generate an analog signal that symbolizes the intensity of muscular action. It is frequently used for isolated EMG recording with NL844/NL820A.

Digital Modules
In addition to being frequently utilized to complicate pulse timing procedures, the digitally controlled NL405 Width/Delay and NL603 Counter can also be used to prolong or count TTL inputs. For more complex signal processing where several inputs influence an output process, further modules in this category, like the NL501 Logic Gate, can be employed.

Filter & Conditioner Modules
Our selection of single- and multi-channel filters, as well as signal conditioning modules, are made to enable accurate signal detection against a backdrop of unrelated frequencies. A 50/60Hz notch filter and adjustable high and low cut settings are included in the NL125/6 band-pass filter. The NL125/6 is frequently used for extracellular and intracellular recording with the NL100AK/NL104A or our NL102G amplifiers. In EEG and EMG applications, Digitimer’s four channel filters are designed to be used with our NL844/NL820A isolated amplifier. For a variety of more specialized roles, other modules in this category, like the NL143 Difference Amplifier, have been developed.

Generator Modules
The "clocks" of the NeuroLog System are the NL301 Pulse Generator and NL304 Period Generator, which enable users to set up stimulus timing protocols with varying degrees of complexity. It is possible to create protocols that use repeating bursts or trains that can go on indefinitely or end after a set amount of time or pulses by adding additional modules. A straightforward hand-held trigger is available with our NL412 Pulse device to start stimulation sequences.

Neurolog System Cases
The NL905 or NL900D Case and Power Supply Unit is the engine that drives the NeuroLog System. These cases offer cable-free communication between modules in addition to housing and powering the individual components. This not only lowers expenses, but also prevents tangled wires from clogging up the front panel controls. The NL900D is a 19" rack or bench-mountable option that can accept up to 13 modules, while the NL905 is a small bench-top unit that can hold up to 4 modules. To hide empty slots, each can be given blank panels.
