Lunchtime learning webinar series on Interdisciplinarity in Action

Mastering a musical instrument, such as the piano, requires the simultaneous integration of a multimodal, sensory system and motor information with multimodal, sensory feedback mechanisms that continuously monitor the performance. Performing intricate movements requires complex, sensory-motor programming of finger and hand movements, which can result in a reorganisation of the brain regarding functional and structural changes of existing and the establishment of new connections. Neuronal networks involved in music processing are adaptable and fast-changing. When motor skills are simplified to the most important action, it consists of nerve impulses sent to the muscles.

In this webinar, Dr Frelét de Villiers discusses the interdisciplinarity between the two fields of music and neuroscience. Promising preliminary data has been reported for applications of transcranial direct stimulation (tDCS) of the motor cortex, ranging from stroke rehabilitation to cognitive enhancement. These findings raise the alternative possibility that the fine motor control of pianists may be improved by stimulating the contralateral motor cortex. 

In our interdisciplinary study, we want to use the Halo Sport neurostimulation system (a physical training aid). This is a tDCS device, designed to optimise the efficiency of training sessions and accelerate gains in any physical skill, especially when the neurostimulation is complemented by focused repetitive training. The main questions of the study are the following: do pianists experience a noticeable difference in mastering repertoire with and without the HALO Sport device, and can functional and structural changes in the brain be observed after using the Halo Sport consistently over six months? Data collection will consist of EEG tests, fMRI scans, interviews, and analysis of performances by an expert panel. The value of the research is the possibility that practising with the HALO may improve the performance of the students and that changes in the brain may be observed. Interdisciplinary engagement is essential to conduct this research. If it is possible to establish that there are functional and structural changes in the brain and improvement in the performance of the pianists, the research can be extended to other disciplines with hopefully the same positive results.

This webinar is part of a series of three webinars on Interdisciplinarity that will be presented from November to December 2020 via Microsoft Teams for a duration of 45 minutes each. The webinar topics in the series will explore the intersection between Neuroscience and Music, between Science and Entrepreneurship, and between Science and Visual Arts.  

Date: Thursday 5 November 2020
Topic: The intersection between neuroscience and music 
Time: 13:00-13:45
RSVP: Alicia Pienaar, pienaaran1@ufs.ac.za by 4 November 2020 at 12:00
Platform: Microsoft Teams

Introduction and welcome
Prof Corli Witthuhn – Vice-Rector: Research at the University of the Free State 

Presenter
Dr Frelét de Villiers

Dr de Villiers is a Senior Lecturer at the Odeion School of Music. She is head of the Methodology modules, short learning programmes, lectures in piano, music pedagogy, arts management, and is a supervisor for postgraduate students. She is a member of the Faculty of the Humanities Research Committee, Interdisciplinary Centre for Digital Futures, Scientific Committee (Arts), and the Ethics Committee (the Humanities). Her field of expertise is piano technique, with particular emphasis on the influence of the brain and the whole-brain approach to music. Her passion is the use of technology in the music teaching situation – she developed a note-learning app, PianoBoost (available on Google Play).

Mineral named after UFS professor
2017-09-29

Description: Mineral tredoux Tags: International Mineralogical Association, tredouxite, Prof Marian Tredoux, Department of Geology, Barberton 

Tredouxite (white) intergrown with bottinoite (light grey),
a complex hydrous alteration product. The large host
minerals are nickel-rich silicate (grey), maybe willemseite,
and the spinel trevorite (dark grey).


More than five thousand minerals have been certified by the International Mineralogical Association (IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification website, the Mineralogical Magazine and the European Journal of Mineralogy.
