Brite23 and OctaMon

Lightweight, multi-channel, wireless cerebral NIRS systems for research

 

Brite23

Brite23 is a lightweight, user-friendly and plug-and-play device with no set-up time. It works with multichannel LED’s, giving you continuous and real-time feedback in our data analysis software that is delivered with the system.

Initially the Brite was developed to measure the effect of cognitive interventions using portable and user-friendly fNIRS. With the Brite23 we enable you to monitor brain activity without the use of large intimidating scanners. The Brite research package makes monitoring oxygenation easy and accessible. Hyperscanning (monitoring multiple subjects at the same time) can be easily done, while our software enables you to combine different NIRS devices within one data stream.

  • Our latest 23-channel fNIRS device
  • Measure oxy-, deoxy-, and total hemoglobin concentration changes on the full prefrontal cortex
  • Truly portable brain oxygenation monitoring
  • Virtually no set-up time
  • Most suitable fNIRS device on the market for physiological and sport exercises (lightweight < 300 grams)
  • 23 high quality measurement channels
  • Hyperscanning
  • Both inside and outside the lab

Subjects are able to perform physical activities like walking, running and climbing while the device is connected with bluetooth (up to 30 meters) to the laptop. The Brite also perfectly complements with our other portable NIRS devices e.g. for measures muscle oxygenation. This makes it the most suited fNIRS device for athletes on the market. The soft neoprene headcap and the portability of the system makes monitoring the brain oxygenation status of elderly, children and vulnerable patients especially safe and easy.  Main applications can be found in: brain oxygenation monitoring, sports science, functional studies, cerebral studies and hyperscanning.

OctaMon

Octamon_tabletThe OctaMon is ideal for capturing brain activity while having the freedom to perform daily activities including exercise. The device consists of 8 channels covering the prefrontal cortex. Like the PortaLite, the OctaMon measures changes in oxygenation in terms of oxyhemoglobin, deoxyhemoglobin and total hemoglobin. This device can be applied in a variety of dynamic settings as often required in neuroscience and sports science research.

This NIRS device is unique in it’s kind. Other similar 8-channel NIRS systems are often non-portable, heavy, expansive, complicated and take a long time to set-up. Coming from the research field ourselves we wanted to change that. With the OctaMon we focussed on the usability and portability of NIRS while still providing the same quality of data as measured by large NIRS systems. The OctaMon is a lightweight and plug and play device with no set-up time. It works with multichannel LED’s, giving you continuous and real-time feedback in our data analysis software that is delivered with the system.

  • Measures oxy-, deoxy- and total hemoglobin in a non-invasive and truly portable way
  • 8 high quality measurement channels
  • Truly portable brain oxygenation monitoring
  • Virtually no set-up time
  • Non-invasive & continuous monitoring
  • Use the lab and in the field
  • No need for special infrastructure
  • No need for specially trained personnel
  • Hyperscanning

The Octamon research package makes monitoring oxygenation easy and accessible. Hyperscanning (monitoring multiple subjects at the same time) is also possible with the OctaMon, while our software provides you to combine different NIRS devices within one data stream. The subjects are able to perform physical activities like walking or running, while the device is connected with bluetooth (up to 100 meters) to the laptop.

The OctaMon is ideally suited to investigate cognitive functions, especially during dual tasking (for example combined with driving or walking). The prefrontal brain regions is in particular studied in working memory or attention tasks, but is also of particular interest for studying neuropathological disorders such as Alzheimer’s disease or ADHD. This is because of its strong interconnection with deeper brain regions, such as the Basal Ganglia. The headband covers a large area of the brain so it could also be used for detecting epileptic seizures.

FAQ's

Brite23 wireless NIRS (9)

This is really dependent on the signal quality. Typically for normal cortical penetration you will want anywhere from 3cm up, the larger the distance the deeper the penetration however at the sake of a reduced signal-to-noise ratio. Typically for normal adults we employ a 3.5cm interoptode distance, for those with darker skin or dark/dense hair you may need to reduce this to achieve an ideal SNR. For younger children and infants often times 2.5cm is more common.

Lasers often require greater consideration in application. There are certainly constraints with regard to motility with a laser based setup that may not be of any concern with LED. Preparation times are often greater with laser than LED, as lasers are often added to a headcap one by one, whereas LED sources could sometimes be “pre-populated”.

Lasers naturally provide a very focal output and are excellent with narrow band frequency emission, thus the ability to discretely “tune” the light output is perhaps of some value, as you might imagine when studying the dispersion of light. Additionally modulation of lasers can take place many times fast than that of LED, as there are some capacitive “left-overs” with LED

fNIRS is of course a completely different modality than fMRI, however while the mechanics may differ there is overlap in the resulting measurements, ultimately cerebral blood flow and metabolic measurements may be obtained, and neuronal activation often assumed. fNIRS is specific to oxygenated and deoxygenated hemoglobin measurement and quantification due to light back reflection, while fMRI aligns the orientation of the hemoglobin depending on the presence of oxygen. fNIRS offers a much better temporal resolution often 100x or more, while spatially fMRI has the upper hand by roughly 10x.

Very good, and important, question. Clearly fNIRS is employing frequencies of light that are purposely used to traverse the skull without much restraint, and this is in fact introducing exogenous stimuli. Well don’t fret, the amount of signal power using fNIRS can be comparable to sunlight. Further, of recent, several studies suggest there are various health benefits to infrared light stimulation at the cellular/metabolic level- even still these studies primarily employ chronic use.

This is a tough one, inherently hair is the nemesis of any fNIRS device on the market and while we all would like to say we have this completely figured out it ultimately comes down to proper preparation, part of which is also a skill in performing. I would use the same criteria with regard screening as you may normally do with EEG.

OxySoft is developed for use with Windows 7 or 10, both are supported however Windows 7 is still preferred. We also offer a free Android application for the PortaLite and PortaMon units for streaming and data logging.

Both PortaLite and PortaMon units use a bluetooth connection with a long range antenna up to 150 meters is possible. The Brite 23 system offers a range of 30 meters.

Yes, you may stream up to 7 devices, both wired (OxyMon), and wireless devices (Brite 23, PortaMon/PortaLite) to the same acquisition PC in real time.
