  1. 1. Error-related potentials and error awareness : A meta-analysis

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Karlien De Temmerman; [2023]
    Nyckelord :Error-related negativity; error‐related positivity; meta‐analysis; error monitoring; error awareness;

    Sammanfattning : Performance monitoring is a crucial metacognitive function that allows for adaptive behaviour. Electrophysiological studies on error monitoring specifically, have shown how error trials in different tasks elicit two distinct signatures, the error-related negativity (ERN) and the error positivity (Pe).

  3. 2. EVOKED PHASE COHERENCE AS A BIOMARKER FOR ADAPTIVE NEUROMODULATION IN RAT MODEL OF PARKINSON'S DISEASE

    Master-uppsats, Umeå universitet/Institutionen för psykologi

    Nyckelord :Adaptive; Closed Loop; Neuromodulation; Parkinson’s Disease; Rat model; 6-OHDA; ITC; Phase Coherence; Bayesian Model; Classifier; Spinal Cord Stimulation; Deep Brain Stimulation.; Adaptiv; Closed Loop; Neuromodulation; Parkinson’s Sjukdom; Råttmodell; 6-OHDA; ITC; Faskoherens; Bayesiansk Modell; Klassificerare; Ryggradsstimulering; Djup Hjärnstimulering.;

    Sammanfattning : Neuromodulation, such as spinal cord stimulation (SCS) and deep brain stimulation (DBS), has been shown to modulate pathophysiological brain activity and provide symptomatic therapy for several neurological disorders, including Parkinson’s Disease. The effectiveness of this therapy could likely be further improved by neuromodulation that is adaptive, delivering stimulation more selectively, by monitoring a biomarker in recorded brain signals, which indicates the presence of a pathological state.

  4. 3. Deep Learning for Driver Sleepiness Classification using Bioelectrical Signals and Karolinska Sleepiness Scale

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Maja Jonsson; Jennifer Brown; [2021]
    Nyckelord :Sleepiness detection; EEG; KSS; deep learning; driving; classification;

    Sammanfattning : Driver sleepiness contributes to a large amount of all road traffic crashes. Developing an objective measurement of driver sleepiness in order to prevent eventual traffic accidents is desirable. LÄS MER

  5. 4. A 3D-printed  Fat-I BC-enabled prosthetic  arm: Control  based on brain neuronal data

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Sahana Ravikumar; [2021]
    Nyckelord :;

    Sammanfattning : Neuroprosthetics enhance a variety of artificial devices that can beused to improve the quality of motor, sensory defects that emerge frombrain-injuries. Brain-Computer interface, as the name suggests,en compasses the interaction between brain and environment. LÄS MER

  7. 5. Electromagnetic Shielding of Fine Wires for Electrophysiological Sensing

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Simon Mogren; [2020]
    Nyckelord :;

    Sammanfattning : Tests have been performed to determine whether electromagnetic shielding of fine wires for electrophysiological sensing is a possible way to reduce the external noise in recording of nervous signals. By shielding the wires with a layer of silver, forming a coaxial cable, a reduction of the received power on the lead of 11. LÄS MER
