Phrase frequency analysis on fNIRS hyperscanning with Stork Big Analysis

September 29th, 2019

In the previous blog, we have used Stork’s big analysis to analyze the literature of fNIRS. At that time, Stork only analyzed the frequency of a single word (number indicates the number of occurences):

near-infrared (1945)
spectroscopy (1868)
cerebral (1850)
brain (1322)
oxygenation (801)
functional (775)
imaging (558)
prefrontal (541)
infrared (498)
cortex (469)
oxygen (467)
blood (413)
monitoring (402)
activation (391)
optical (367)
fnirs (364)
patients (364)
activity (342)

Some of the words, such as spectroscopy, brain, functional, imaging etc, are not very meaningful by itself. Maybe they are part of phrases which carry more information than a single word does.

Today, Stork Big Analysis has updated and now it can analyze frequency of phrases with 2, 3, and 4 words. Below is the result with the same keywords (fnirs OR nirs OR "near infrared") brain:

Top phrase (2 words):

cerebral oxygenation (362)
infrared spectroscopy (344)
prefrontal cortex (262)
oxygen saturation (243)
cerebral blood (218)
cerebral oxygen (201)
blood flow (184)
brain injury (128)
preterm infants (127)
cerebral hemodynamics (102)
cerebral oximetry (98)
regional cerebral (96)
tissue oxygenation (95)
brain activity (90)
working memory (85)

Top phrase (3 words):

cerebral blood flow (134)
cerebral oxygen saturation (129)
traumatic brain injury (71)
cerebral blood volume (57)
regional cerebral oxygen (53)
verbal fluency task (43)
prefrontal cortex activity (38)
cerebral tissue oxygenation (37)
tissue oxygen saturation (36)
prefrontal cortex activation (35)
magnetic resonance imaging (32)
diffuse optical tomography (31)
transcranial magnetic stimulation (30)
positron emission tomography (26)
cerebral tissue oxygen (25)
hypothermic circulatory arrest (23)
transcranial direct current (22)

Top phrase (4 words):

regional cerebral oxygen saturation (52)
cerebral tissue oxygen saturation (24)
transcranial direct current stimulation (21)
deep hypothermic circulatory arrest (15)
functional magnetic resonance imaging (15)
cerebral tissue oxygenation index (12)
repetitive transcranial magnetic stimulation (12)
attention deficit hyperactivity disorder (11)
regional cerebral blood flow (9)
cerebral oxygen saturation measured (9)
cerebral blood flow velocity (8)
severe traumatic brain injury (8)
cerebral regional oxygen saturation (7)
cerebral oxygen saturation monitoring (7)
coronary artery bypass grafting (7)
red blood cell transfusion (6)
hypoplastic left heart syndrome (6)
cerebral blood flow autoregulation (6)
mild traumatic brain injury (5)
anodal transcranial direct current (5)
resting state functional connectivity (5)
mixed venous oxygen saturation (5)

We see some meaningful phrases show up. A single word such as “blood” now has a clearer meaning (e.g. “cerebral blood flow”). We also discovered a few top phrases which we can’t find with a single word analysis, such as “verbal fluency task”. This is a popular task used in fNIRS studies but I have not realized it is that popular! “Traumatic brain injury” is another example, showing the popular application of fNIRS in diagnose this condition.

fNIRS overview by Stork’s Big Analysis

August 8th, 2019

What’s the trend of fNIRS in brain research? Is the field growing or dying? Which country and which institute are the most productive? Who are the experts in the field and how can I contact them for collaboration? Which brain region(s) are mostly studied? Which disorder appears most frequently in the publications?

These are important questions to ask. However, even to a reseacher who works in the field (brain research with fNIRS), the answers may not readily available. Fortunately, Stork team’s new advanced feature “Big Analysis” makes it very easy to get the answers. As a matter a fact, it only required me to enter the keyword, and then it downloaded and analyzed about 6,500 publications and generated beautiful reports in less than 3 minutes.

Below is a screenshot of the report using keyword: (fnirs OR nirs  OR “near infrared”) brain

Now we see, fNIRS research on the brain is growing steadily over the past 20 years, with recent growth ~10%. US, Japan, Germany and China are the top countries in this field. National Insitute of Radiological Sciences, UCL and Harvard are top institutes. The top diseases studied are Stroke, Brain Injury, Schizophrenia and Stress. NeuroImage, Adv Exp Med Biol, J Biomed Opt are top journals where the research is published. The mostly studied brain region is the frontal lobe. Some experts in the field are shown too, such as Hongjie Dai, David Boas, Allan Reiss, and Ilias Tachtsidis etc. Stork also shows the author network graph. It’s an interactive graph and it’s fun to drag things around to find out who are connected to who.

Most of the experts’ emails are available. That means when I want to contact them for collaboration, or invite them to review a paper, I don’t have to spend time in digging their emails.

The “Big Analysis” tool can be purchased through Stork website. The description can be found at here.

How to find NIRS experts using “Find Experts” app

January 12th, 2018

If you are a newcomer in the NIRS field, you may wonder who are the experts in this field. You might know a few already - for example your boss. But who else are there and where they are?

We developed “Find Experts” app to quickly find experts based on scientific publications in any biomedical field. Let’s see who are experts in the NIRS field.

How to track new NIRS publications and grants?

October 27th, 2017

Near infrared spectroscopy (NIRS) is an increasingly popular technology in brain imaging research. Compared to fMRI, NIRS can be used for more naturalistic experiments, including face to face communication, natural body movements, sports, infants, and is well suited for real-time applications.

If we count the number of NIRS publications using keyword (NIRS OR fNIRS) AND brain, we find the number increases steadily over the past 10 years:

With this trend, it’s expected that we will reach a speed of 1 new paper every day in the year of 2018 or 2019. This is a fast field, and it’s nearly impossible for us to search (NIRS OR fNIRS) AND brain every day or even every week. For a student who does not follow literature proactively, he might know of a paper a year after its publication.

The easiest way to solve this problem is to use an app to notify us of the new publications. The one I use is called Stork . All I need to do is to enter a few keywords I am interested in, e.g.:


But what if I want to follow more specific fields, such as hyperscanning, or comparison with fMRI etc? We can enter the following keywords:
(NIRS OR fNIRS) AND brain AND hyperscanning
(NIRS OR fNIRS) AND brain AND "deep learning"
(NIRS OR fNIRS) AND brain AND social

What if I want to follow some scientists in the field? We may enter their names, such as:
David Boas
Allan Reiss (NIRS or fNIRS)

After we setup the keywords, Stork, like a diligent assistant, will search for us every day. If she finds something, she will send an email to us, listing the new publications. A recent example is shown below:

fmri nirs

The Temporal Muscle of the Head Can Cause Artifacts in Optical Imaging Studies with Functional Near-Infrared Spectroscopy. by Martin Schecklmann, Alexander Mann, …, Florian B Haeussinger (2017) Front Hum Neurosci (impact factor: 3.6) Free full text

nirs brain

Enhancing Performance of a Hybrid EEG-fNIRS System Using Channel Selection and Early Temporal Features. by Rihui Li, Thomas Potter, Weitian Huang, Yingchun Zhang (2017) Front Hum Neurosci (impact factor: 3.6)Free full text

Not only does Stork search scientific publications for you, she also searches NIH grant database (this is an advanced feature). That means whenever some researchers receive a grant on NIRS, you will know it. You will know what is his research direction in the next few years, how much money he received etc. This feature is mostly useful for professors and senior graduate students and postdocs.

The link of Stork is: and it’s very easy to use.
