  1. 1. Subsystems of the basal ganglia and motor infrastructure

    Författare :Iman Kamali Sarvestani; Örjan Ekeberg; Jeanette Hällgren-Kotaleski; Christelle Baunez; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Basal Ganglia; Action Selection; Motor Learning; Tectum; Superior Colliculus; Mesencephalic Locomotor Region; Reticulospinal Neurons; Computational Models;

    Sammanfattning : The motor nervous system is one of the main systems of the body and is our principle means ofbehavior. Some of the most debilitating and wide spread disorders are motor systempathologies. In particular the basal ganglia are complex networks of the brain that control someaspects of movement in all vertebrates. LÄS MER

  3. 2. Cerebellar Control of Classical Conditioning

    Författare :Magnus Ivarsson; Neurofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Associative module; Bilateral; Orbicularis oculi muscle; Inferior olive; Purkinje cell; Eyeblink; Conditioned response; neuropsykologi; neurofysiologi; Neurologi; neurophysiology; neuropsychology; Neurology;

    Sammanfattning : It has previously been shown that the cerebellum is critical for classical conditioning. The experiments presented in this thesis aimed to study how the cerebellum controls conditioned eyeblink responses (CRs) and specifically the efferent path from the cerebellar cortex to the muscles.

  4. 3. Investigations of neural attractor dynamics in human visual awareness

    Författare :David N. Silverstein; Pawel Herman; Martin Ingvar; Karl Friston; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; attractor dynamics; visual awareness; visual perception; visual attention; attentional blink; backward masking; gliomas; brain tumor; white matter; cell assemblies; neocortical model; threat response; fear signaling; amygdala; Biological Physics; Biologisk fysik; Computer Science; Datalogi; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : What we see, how we see it and what emotions may arise from stimuli has long been studied by philosophers, psychologists, medical doctors and neuroscientists. This thesis work investigates a particular view on the possible dynamics, utilizing computational models of spiking neural attractor networks. LÄS MER
