  1. 1. ERP and MEG Correlates of Visual Consciousness : An Update

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Jona Förster; [2019]
    Nyckelord :Neural correlates of consciousness; Event-related potentials; Event-related fields; Visual awareness negativity; Late positivity; Global Neuronal Workspace theory; Recurrent Processing theory;

    Sammanfattning : Two decades of event-related potential (ERP) research have established that the most consistent correlates of the onset of visual consciousness are the early visual awareness negativity (VAN), a negative component in the N2 time range over posterior electrode sites, and the late positivity (LP), a positive component in the P3 time range over fronto-parietal electrode sites. A review by Koivisto & Revonsuo (2010) had looked at 39 studies and concluded that the VAN is the earliest and most reliable correlate of visual phenomenal consciousness, whereas the LP probably reflects later processes associated with reflective/access consciousness.

  2. 2. Evaluation of cognitive workload using EEG : Investigation of how sensory feedback improves function of osseo-neuromuscular upper limb prostheses

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Linn Berntsson; [2019]
    Nyckelord :EEG; ERP; spectral analysis; cognitive workload; prosthesis;

    Sammanfattning : The e-OPRA Implant System (Integrum AB, Sweden) is a system which employs permanently accessible implantable neuromuscular electrodes in combination with osseointegrated attachment of the prosthesis to the skeleton, in order to create a more natural control of advanced robotic upper-limb prostheses. The system enables the possibility of sensory feedback, via a cuff electrode to the ulnar nerve which allows for direct neurostimulation of the nerve. LÄS MER

  3. 3. Visual Perception of the Facial Width-to-Height Ratio : Possible Influences of Angry Facial Expressions as Revealed by Event-Related Brain Potentials

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Madeleine Jones; [2019]
    Nyckelord :Facial Width-to-Height Ratio; Late Positive Potential; Facial Processing; Anger; Cognitive Neuroscience;

    Sammanfattning : The facial width-to-height ratio (fWHR) is a measure of the cheekbone width divided by the height of the face from the upper lip to the brows. The metric is hypothesised to have evolved as an intra-sexual competition mechanism in males, where large fWHRs are thought to signal both threat and aggression. LÄS MER

  4. 4. An Exploration of Temporal Context in the Recollection of Previously Encoded Events

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Madeleine McCallum; [2019]
    Nyckelord :Episodic memory; recollection; cued-recall; EEG; LPN; Social Sciences;

    Sammanfattning : The effect of temporal context in the encoding and retrieval of facial stimuli was examined based on behavioural and EEG data collection during a cued recall memory task. Participants were found to have greater accuracy in their recollection of serial list items encoded before a correctly retrieved facial stimulus in comparison to those encoded after a correctly retrieved facial stimulus.

  5. 5. Exploring the Neural Correlates of Auditory Awareness

    Master-uppsats, Stockholms universitet/Psykologiska institutionen

    Författare :Billy Gerdfeldter; [2018]
    Nyckelord :consciousness; awareness; audition; event-related potential; auditory awareness negativity; AAN;

    Sammanfattning : Neural correlates of consciousness (NCCs) represent the physiological processes related to consciousness and awareness. Consciousness is theorized as a recurrent process of integration between separate but specialized brain areas. LÄS MER
