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.

Topic: The intersection between neuroscience and music 
Time: 13:00-13:45

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).

Fracking in the Karoo has advantages and disadvantages

Fracking for shale gas in the Karoo was laid bare during a public lecture by Dr Danie Vermeulen, Director of the Institute for Groundwater Studies (IGS). He shared facts, figures and research with his audience. No “yes” or “no” vote was cast. The audience was left to decide for itself.

The exploitation of shale gas in the pristine Karoo has probably been one of the most debated issues in South Africa since 2011.
 
Dr Vermeulen’s lecture, “The shale gas story in the Karoo: both sides of the coin”, was the first in a series presented by the Faculty of Natural and Agricultural Science under the theme “Sustainability”. Dr Vermeulen is a trained geo-hydrologist and geologist. He has been involved in fracking in South Africa since the debate started. He went on a study tour to the USA in 2011 to learn more about fracking and he visited the USA to further his investigation in May 2012.
 
Some of the information he shared, includes:

- It is estimated that South Africa has the fifth-largest shale-gas reserves in the world, following on China, the USA, Argentina and Mexico.
- Flow-back water is stored in sealed tanks and not in flow-back dams.
- Fracturing will not contaminate the water in an area, as the drilling of the wells will go far deeper than the groundwater aquifers. Every well has four steel casings – one within the other – with the gaps between them sealed with cement.
- More than a million hydraulic fracturing simulations took place in the USA without compromising fresh groundwater. The surface activities can cause problems because that is where man-made and managerial operations could cause pollution.
- Water use for shale-gas exploration is lower than for other kinds of energy, but the fact that the Karoo is an arid region makes the use of groundwater a sensitive issue. Dr Vermeulen highlighted this aspect as his major concern regarding shale-gas exploration.
- The cost to develop is a quarter of the cost for an oil well in the Gulf of Mexico.
- Dolerite intrusions in the Karoo are an unresearched concern. Dolerite is unique to the South African situation. Dolerite intrusion temperatures exceed 900 °C.

He also addressed the shale-gas footprint, well decommissioning and site reclamation, radio activity in the shale and the low possibility of seismic events.
 
Dr Vermeulen said South Africa is a net importer of energy. About 90% of its power supply is coal-based. For continued economic growth, South Africa needs a stable energy supply. It is also forecast that energy demand in South Africa is growing faster than the average global demand.
 
Unknowns to be addressed in research and exploration are the gas reserves and gas needs of South Africa. Do we have enough water? What will be the visual and social impact? Who must do the exploration?
 
“Only exploration will give us these answers,” Dr Vermeulen said.
