  1. 1. Transcranial magnetic stimulation induced blindsight : A systematic review

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Simon Redlund; Ellen Carlsson; [2023]
    Nyckelord :Blindsight; TMS; transcranial magnetic stimulation; visual cortex; unconscious;

    Sammanfattning : Blindsight is a phenomenon in which patients suffering damage to the primary visual cortex (V1) perceive themselves as blind, but nonetheless seem to have some residual capacity to distinguish between visual stimuli better than chance. Blindsight can be divided into two subtypes: blindsight type I and blindsight type II. LÄS MER

  3. 2. Functional and Dynamical Consequences of Long-Range Patchy Connections in the Primary Visual Cortex

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Leo Laurenz Zeitler; [2020]
    Nyckelord :;

    Sammanfattning : While it is a known fact that higher mammals develop a differently structured primary visual cortex than rodents, the reason for this phenomenon remains unknown. Eutherian species that rely primarily on vision establish long-range patchy connections between locally clustered neurons. LÄS MER

  4. 3. Stroop tasks with visual and auditory stimuli : How different combinations of spoken words, written words, images and natural sounds affect reaction times

    Kandidat-uppsats, Stockholms universitet/Institutionen för lingvistik

    Författare :Christina Malapetsa; [2020]
    Nyckelord :Stroop effect; reaction times; interference; inhibition; executive functions; processing time; linguistic stimuli; visual stimuli; auditory stimuli;

    Sammanfattning : The Stroop effect is the delay in reaction times due to interference. Since the original experiments of 1935, it has been used primarily in linguistic context. Language is a complex skill unique to humans, which involves a large part of the cerebral cortex and many subcortical regions. LÄS MER

  5. 4. Two subtypes of lung cancer classification from histopathology images based on deep learning

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Xiao Chen Shen; [2019]
    Nyckelord :deep learning; lung cancer; transfer learning; ensemble learning; Physics and Astronomy;

    Sammanfattning : Adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC) are the most common forms of lung cancer. These two subtypes of lung cancer are usually classified by visual inspection clinically. Our aim is to design an effective strategy based on convolutional neural networks to classify histopathology slides of these two types of lung cancer. LÄS MER

  7. 5. Trippelkodmodellen : hur barnhjärnor hanterar numeriska uppgifter

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Patric Halénius; [2019]
    Nyckelord :;

    Sammanfattning : Att kunna uppskatta antal är en grundläggande förmåga som återfinns hos många djur förutom männinskan. Trippelkodmodellen (TKM) för numerisk kognition säger att antal representeras på tre olika sätt, som (arabiska) siffror, som sifferord och som ickesymboliska magnituder, vilka associeras till separata, men delvis överlappande, neurala substrat.
