​Reprezentacije položaja v prostorskem delovnem spominu
Nina Purg, Grega Repovš, Alan Anticevic
Doktorska disertacija
Oznake: prostorski delovni spomin;fMR;vkodiranje;vzdrževanje;reprezentacije;strategije kodiranja;
Uvod: Vzdrževana aktivnost v frontalnih in parietalnih možganskih področjih med prostorskim delovnim spominom bi naj odražala procese aktivnega shranjevanja in vzdrževanja informacij, vendar narava reprezentacij, zabeleženih v tej aktivnosti, ostaja neznana. Namen doktorske disertacije je bil razisk ...

autohrf-an R package for generating data-informed event models for general linear modeling of task-based fMRI data
Nina Purg, Jure Demšar, Alan Anticevic, Grega Repovš
Izvirni znanstveni članek
Oznake: funkcijsko magnetnoresonančno slikanje fMRI;možgani;splošno linearno modeliranje;predpostavljeno modeliranje;računalniški programi;R;functional magnetic resonance imaging fMRI;brain;general linear modeling GLM;assumed modeling;computer software;
The analysis of task-related fMRI data at the level of individual participants is commonly based on general linear modeling (GLM), which allows us to estimate the extent to which the BOLD signal can be explained by the task response predictors specified in the event model. The predictors are constru ...

Evaluation and comparison of most prevalent artifact reduction methods for EEG acquired simultaneously with fMRI
Aleksij Kraljič, Andraž Matkovič, Nina Purg, Jure Demšar, Grega Repovš
Izvirni znanstveni članek
Oznake: elektroencefalografija EEG;funkcijsko magnetnoresonančno slikanje fMRI;nevroznanost;slikanje možganov;možgani;metodologija;electroencephalography EEG;functional magnetic resonance imaging fMRI;neurosciences;neuroimaging;brain;methodology;
Multimodal neuroimaging using EEG and fMRI provides deeper insights into brain function by improving the spatial and temporal resolution of the acquired data. However, simultaneous EEG-fMRI inevitably compromises the quality of the EEG and fMRI signals due to the high degree of interaction between t ...

Neural evidence for different types of position coding strategies in spatial working memory
Nina Purg, Martina Starc, Anka Slana, Aleksij Kraljič, Andraž Matkovič, Grega Repovš
Izvirni znanstveni članek
Oznake: delovni spomin;prostorski spomin;funkcijsko magnetnoresonančno slikanje fMRI;možgani;kognitivna psihologija;short term memory;spatial memory;functional magnetic resonance imaging fMRI;brain;cognitive psychology;
Sustained neural activity during the delay phase of spatial working memory tasks is compelling evidence for the neural correlate of active storage and maintenance of spatial information, however, it does not provide insight into specific mechanisms of spatial coding. This activity may reflect a rang ...

ǂThe ǂdiversity of strategies used in working memory for colors, orientations, and positions
Anka Slana, Aleš Oblak, Urban Kordeš, Nina Purg, Jurij Bon, Grega Repovš
Izvirni znanstveni članek
Oznake: delovni spomin;strategije;interpretativna fenomenološka analiza;vidno-prostorski spomin;working memory;strategies;interpretative phenomenological analysis;visuospatial memory;
The study of individual experience during the performance of a psychological task using a phenomenological approach is a relatively new area of research. The aim of this paper was to combine first- and third-person approaches to investigate whether the strategies individuals use during a working mem ...

What is it like to do a visuo-spatial working memory task
Aleš Oblak, Oskar Dragan, Anka Slana, Urban Kordeš, Nina Purg, Jurij Bon, Grega Repovš
Izvirni znanstveni članek
Oznake: vidni razpon;delovni spomin;fenomenologija;merjenje;psihološka naloga;nevrofenomenologija;visual span;short term memory;phenomenology;measurement;psychological task;neurophenomenology;
Working memory is typically measured with specifically designed psychological tasks. When evaluating the validity of working memory tasks, we commonly focus on the reliability of the outcome measurements. Only rarely do we focus on how participants experience these tasks. Accounting for lived experi ...

Individual differences in spatial working memory strategies differentially reflected in the engagement of control and default brain networks
Nina Purg, Aleksij Kraljič, Masih Rahmati, Youngsun T. Cho, Anka Slana, John D. Murray, Alan Anticevic, Grega Repovš

Spatial locations can be encoded and maintained in working memory using different representations and strategies. Fine-grained representations provide detailed stimulus information, but are cognitively demanding and prone to inexactness. The uncertainty in fine-grained representations can be compens ...
