A high-density EEG study of differentiation between two speeds and directions of simulated optic flow in adults and infants
Vilhelmsen, Kenneth; Agyei, Seth Bonsu; Van der Weel, Frederikus; Van der Meer, Audrey (Journal article; Peer reviewed, 2018)A high‐density EEG study was carried out to investigate cortical activity in response to forward and backward visual motion at two different driving speeds, simulated through optic flow. Participants were prelocomotor ... -
Development of visual motion perception for prospective control: Brain and behavioral studies in infants
Agyei, Seth Bonsu; Van der Weel, Frederikus; Meer, Audrey van der (Journal article; Peer reviewed, 2016)During infancy, smart perceptual mechanisms develop allowing infants to judge time-space motion dynamics more efficiently with age and locomotor experience. This emerging capacity may be vital to enable preparedness for ... -
Efficiency in visual processing: A high-density EEG study investigating N2 responses to structured optic flow and random visual motion
Johnson, Jørgen Espolin (Bachelor thesis, 2023)Når vi beveger oss gjennom et miljø erfarer vi en optisk scene som forandrer seg konstant. Denne scenen kalles optisk flyt og gir oss informasjon om vår posisjon relativt til miljøet rundt oss. Samtidig prosesserer vi ulike ... -
Exploring Visual Motion Perception Through EEG:The Motion Sensitive N2-Waveform Responses to Structured Optic Flow and Random Visual Motion
Hadzhisadak, Buse Beyhan (Bachelor thesis, 2024)Studien undersøkte kortikal elektrisk aktivitet over den mediale temporale kompleksen (MT+) som respons på strukturert fremover/bakover optisk strømningsmønster og tilfeldig visuell bevegelse, ved hjelp av høy-tetthet ... -
Functional Brain Development: Longitudinal Studies in Infants using High-Density EEG
Agyei, Seth Bonsu (Doctoral theses at NTNU;2021:195, Doctoral thesis, 2021)The thesis examines the functional brain development of visual motion perception in full-term and preterm infants in the first year of life using high-density electroencephalogram (EEG). The relationship between behavioural ... -
Infants' brain responses to looming danger: Degeneracy of neural connectivity patterns
Van der Weel, Frederikus; Agyei, Seth Bonsu; Van der Meer, Audrey (Journal article; Peer reviewed, 2019)A fundamental property of most animals is the ability to see whether an object is approaching on a direct collision course and, if so, when it will collide. Using high-density electroencephalography in infants and a looming ... -
Investigating visual motion perception for prospective control through N2 responses: A high-density EEG study
Smistad, Jan-Ove Dyrli (Bachelor thesis, 2024)Denne studien anvendte høy-tetthets elektroencefalogram for å undersøke forskjeller i posterior cerebral aktivitet som en funksjon av forskjellige visuelle bevegelsesstimuli og som en funksjon av forskjellige aldre i respons ... -
Out of Sight, Out of Mind? Neuronal Gamma Oscillations During Occlusion Events in Infants
Slinning, Regine; Agyei, Seth Bonsu; Kristoffersen, Silje Hognestad; Weel, Frederikus Roelof Ruud van der; Meer, Audrey Lucia Hendrika van der (Journal article; Peer reviewed, 2024)Object permanence allows infants to interact successfully with objects in the environment. What happens in the human infant brain when objects move in and out of sight? This study used high-density electroencephalography ... -
Perception of structured optic flow and random visual motion in adults: A high-density EEG study
Fossvik, Sturla (Bachelor thesis, 2023)Høy-tetthets elektroencefalografi (EEG) ble brukt for å undersøke hjerneaktivitet som funksjonell responsmekanisme til visuelle bevegelsesstimuli hos voksne. Deltakere var friske voksne fra alderen 21 til 37. Bevegelsesstimuli ... -
Understanding Visual Motion Perception for Prospective Control using High-Density EEG
Vollen, Dina Sofie Djenkova (Bachelor thesis, 2023)Høy tetthets elektroencefalogram (HD-EEG) ble brukt på voksne i alderen 21–39 år for å studere hjernens elektriske aktivitet som en funksjon av persepsjon av strukturert optic flow (framover og bakover bevegelse) og ...
