Testing high-density electroencephalogram (EEG) functionality

EEG is a tool used to record brain activity which is widely used in the world of medicine and neuroscience. A high-density EEG (64-channel EEG) offers the possibility of in-depth studies able to shed light on problems related to neuronal disorders, as well to analyse a series of specific waveforms related to electrical brain activity, through the analysis of so-called “evoked potentials“.

Last week, a team of researchers from Sterzing Hospital led by Prof. Leopold Saltuari investigated the possibility of using the high-density EEG in the terraXcube chambers. The objective of the tests was to evaluate and quantify possible sources of noise inside the chamber, which could represent a serious problem in the perspective of future collaborations. Noise is ubiquitous in nature and is typically considered as detrimental during measurement processes: in experimental science every single setup must take into account different measures to try to reduce the impact of noise on the results acquired. During the test, researchers from both Sterzing Hospital and terraXcube have considered several potential sources of noise on the EEG measurement (mechanical noise, electro-magnetical noise, etc.) and defined a preliminary protocol for collaboration. Luckily, the tests have been successful, thus paving the way for a new field of neuroscientific investigation inside terraXcube.
