NYUAD study into sign language and brain function 'shows how similar people are'

Go back 2,300 years and the ancient Greek philosopher Aristotle was arguing that the purpose of the brain was to help to cool the blood. He thought that consciousness was located in our hearts.

Although outlandish, it was perhaps not as ridiculous a suggestion as it appears, given how rich in blood vessels the brain is.

It has, of course, long since been established that our mental processes take place in the brain and not the heart, and even before Aristotle’s time many took this view.

While our knowledge of the structure of the brain and the way in which various functions are located within it has moved on immeasurably, our most complex organ has still not yielded all of its secrets to science. So researchers remain busy attempting to more precisely localise particular functions.

Studies involving New York University Abu Dhabi are helping to provide just such a detailed localisation for certain neural processes involved in language.

In a fascinating 2015 study published in Brain & Language, Professor Liina Pylkkanen, a professor of linguistics and psychology at NYU and an associate faculty member at NYU Abu Dhabi, led a team who found that, when a person composes basic phrases, a part of the brain called the left anterior temporal lobe (LATL) was activated in similar ways for many different types of phrases.

There are four main lobes in the brain’s cerebral cortex (the part of the brain where higher thought processes happen), of which the temporal lobe is one. As indicated by its name, the LATL is a frontal (anterior) section of the left temporal lobe.

In the study, co-authored by NYU researchers Dr Masha Westerlund (now director of data science at Investopedia in New York), Dr Itamar Kastner (now at Humboldt University in Berlin) and Dr Meera Al Kaabi (now an assistant professor at United Arab Emirates University in Al Ain), the same activation pattern – in terms of location and timing – was seen regardless of whether the person was reading English or Arabic.

How the mysteries of language are being mapped


That the neural processes involved in reading phrases in Arabic and English are similar might not seem surprising. After all, in both cases people are understanding written words.

It perhaps seems harder to predict whether this similarity still holds true if, instead of reading, people are generating language and if instead of speaking, the produced language is a sign language. Are the processes in the brain used to generate phrases in a sign language the same as those used to produce spoken phrases?

A new paper looking at this has been published in the journal Scientific Reports. Much of the experimental work was carried out at NYU Abu Dhabi by the lead author, Esti Blanco-Elorrieta. The paper is co-written by Prof Pylkkanen, who is the senior author, along with Dr Kastner and a sign language specialist at San Diego State University, Professor Karen Emmorey.

The study compared results from 11 deaf sign language users in New York and 11 hearing English speakers living in Abu Dhabi. These were NYU Abu Dhabi students or faculty members who had recently moved to the Emirates. They were monolingual and spoke little or no Arabic.

As in the Arabic-English study, language processing in the brain was measured with magnetoencephalography (MEG), which detects the magnetic fields associated with neuronal currents. MEG allows a detailed measurement of both the timing and location of brain activity. All participants performed many trials to produce a stable pattern.

As when comparing Arabic speakers with English speakers, when comparing English speakers and American Sign Language (ASL) users, the researchers found that activity in the same regions of the brain, and at the same time, was triggered.

Finding no difference between ASL and English might not appear to be an exciting result, but Prof Pylkkanen said it was important.

“On the one hand, it’s a boring replication, but on the other hand, it’s amazing because we’re seeing similarity in the face of so much difference,” she said.

“We have to keep in mind the groups are different and we ran these studies in separate countries with different MEG machines.”

It demonstrates a deep-rooted similarity in the brain processes when people compose phrases like “blue cup”, whether these are in sign language or in spoken language.

The researchers had been uncertain, said Prof Emmorey, whether the differences in output (speaking vs signing) would affect the type of computation taking place in the brain, and the timing at which it happened after a stimulus.

“The hands are much slower, but this had no effect on the timing,” said Prof Emmorey.

“[The overall result is] a very good piece of evidence that we’re dealing with something very fundamental to language.”

Finding the same result for both spoken and sign language simplifies the interpretation of the results. Had differences been found, trying to understand the causes may not have been easy.

“If we had seen differences, there could have been many, many [reasons for] the differences. If we saw similarities, they are more likely to be caused by similar linguistic processes,” said Prof Pylkkanen.

Last year, The National reported on another study by Prof Pylkkanen and Blanco-Elorrieta in which they found that only artificial or forced language switching engaged the brain regions called the prefrontal cortex (PFC), which is important for inhibition and executive control, and the anterior cingulate cortex (ACC), which is involved in conflict resolution and error monitoring. When bilingual Arabic and English speakers were allowed to switch languages freely, there was no activation of such regions.

Blanco-Elorrieta is now looking again at neural processes associated with bilingualism (including ASL-English bilingualism), which is the main focus of her PhD.

Under Prof Pylkkanen’s supervision, she is trying to understand how concepts are represented in the bilingual brain. For example, is a particular concept in an English speaker’s mind represented in the same way in the brain as it is for an Arabic speaker? Although there are some cases in which the concepts may fully overlap across languages, there are others in which the translation of a word to the other language does not capture exactly the same meaning.

“We’re interested in looking at the underlying representations – how the different mappings between concepts and words co-exist and relate to each other in the bilingual brain,” said Blanco-Elorrieta.

What is Folia?

Prince Khaled bin Alwaleed bin Talal's new plant-based menu will launch at Four Seasons hotels in Dubai this November. A desire to cater to people looking for clean, healthy meals beyond green salad is what inspired Prince Khaled and American celebrity chef Matthew Kenney to create Folia. The word means "from the leaves" in Latin, and the exclusive menu offers fine plant-based cuisine across Four Seasons properties in Los Angeles, Bahrain and, soon, Dubai.

Kenney specialises in vegan cuisine and is the founder of Plant Food + Wine and 20 other restaurants worldwide. "I’ve always appreciated Matthew’s work," says the Saudi royal. "He has a singular culinary talent and his approach to plant-based dining is prescient and unrivalled. I was a fan of his long before we established our professional relationship."

Folia first launched at The Four Seasons Hotel Los Angeles at Beverly Hills in July 2018. It is available at the poolside Cabana Restaurant and for in-room dining across the property, as well as in its private event space. The food is vibrant and colourful, full of fresh dishes such as the hearts of palm ceviche with California fruit, vegetables and edible flowers; green hearb tacos filled with roasted squash and king oyster barbacoa; and a savoury coconut cream pie with macadamia crust.

In March 2019, the Folia menu reached Gulf shores, as it was introduced at the Four Seasons Hotel Bahrain Bay, where it is served at the Bay View Lounge. Next, on Tuesday, November 1 – also known as World Vegan Day – it will come to the UAE, to the Four Seasons Resort Dubai at Jumeirah Beach and the Four Seasons DIFC, both properties Prince Khaled has spent "considerable time at and love". 

There are also plans to take Folia to several more locations throughout the Middle East and Europe.

While health-conscious diners will be attracted to the concept, Prince Khaled is careful to stress Folia is "not meant for a specific subset of customers. It is meant for everyone who wants a culinary experience without the negative impact that eating out so often comes with."

Pox that threatens the Middle East's native species


Caused by a virus related to the one that causes human smallpox, camelpox typically causes fever, swelling of lymph nodes and skin lesions in camels aged over three, but the animal usually recovers after a month or so. Younger animals may develop a more acute form that causes internal lesions and diarrhoea, and is often fatal, especially when secondary infections result. It is found across the Middle East as well as in parts of Asia, Africa, Russia and India.


Falconpox can cause a variety of types of lesions, which can affect, for example, the eyelids, feet and the areas above and below the beak. It is a problem among captive falcons and is one of many types of avian pox or avipox diseases that together affect dozens of bird species across the world. Among the other forms are pigeonpox, turkeypox, starlingpox and canarypox. Avipox viruses are spread by mosquitoes and direct bird-to-bird contact.


Houbarapox is, like falconpox, one of the many forms of avipox diseases. It exists in various forms, with a type that causes skin lesions being least likely to result in death. Other forms cause more severe lesions, including internal lesions, and are more likely to kill the bird, often because secondary infections develop. This summer the CVRL reported an outbreak of pox in houbaras after rains in spring led to an increase in mosquito numbers.

• An official drinks interval has been called.
• The umpires have approved the on field treatment of an injury to a batter or fielder.
• The time lost is for any circumstances beyond the control of the fielding side.
• The third umpire starts the clock either when the ball has become dead at the end of the previous over, or a review has been completed.
• The team gets two warnings if they are not ready to start overs after the clock reaches zero.
• On the third and any subsequent occasion in an innings, the bowler’s end umpire awards five runs.
