Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.

Abstract (eng): Oscillatory gamma-band activity (GBA) occurring at 30 - 100 Hz has been attributed to cognitive processing.
Evidence to the contrary suggests that induced high-frequency oscillations in the gamma-band EEG are merely artifacts of saccadic eye movement or muscular activity.

This study aimed to review signal processing methods suitable for attenuating saccadic artifacts in EEG data collected from musically trained children and control subjects.
With proper pre-processing, induced auditory GBA responses were found in each age group.
These responses show a pattern consistent with prior research.
More specifically, the frequency and spectral power of the induced gamma-band response appear to be influenced by musical training.

The conclusions of this study support the role of induced GBA in higher level cognitive processing.
