  1. 1. EVOKED PHASE COHERENCE AS A BIOMARKER FOR ADAPTIVE NEUROMODULATION IN RAT MODEL OF PARKINSON'S DISEASE

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Love Zackrisson; [2023]
    Keywords : Adaptive; Closed Loop; Neuromodulation; Parkinson’s Disease; Rat model; 6-OHDA; ITC; Phase Coherence; Bayesian Model; Classifier; Spinal Cord Stimulation; Deep Brain Stimulation.; Adaptiv; Closed Loop; Neuromodulation; Parkinson’s Sjukdom; Råttmodell; 6-OHDA; ITC; Faskoherens; Bayesiansk Modell; Klassificerare; Ryggradsstimulering; Djup Hjärnstimulering.;

    Abstract : Neuromodulation, such as spinal cord stimulation (SCS) and deep brain stimulation (DBS), has been shown to modulate pathophysiological brain activity and provide symptomatic therapy for several neurological disorders, including Parkinson’s Disease. The effectiveness of this therapy could likely be further improved by neuromodulation that is adaptive, delivering stimulation more selectively, by monitoring a biomarker in recorded brain signals, which indicates the presence of a pathological state.

  3. 2. Sex-dependent differences in human reward processing : A systematic review

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Simon Nyqvist Ghashghaian; [2022]
    Keywords : Reward-processing; sex-differences; dopamine; reward pathways; sex hormones;

    Abstract : Much work has been done in the neuroscience of reward processing, such as; mapping brain areas, key neurotransmitters, and connectivity patterns related to different aspects of reward-related behavior. There are a lot of suggested behavioral and neural sex differences in reward processing, primarily based on animal studies of reward behavior. READ MORE

  4. 3. Dopamine Waves Lead to a Swift and Adaptive Reinforcement Learning Algorithm

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gergö Gömöri; [2021]
    Keywords : Reinforcement Learning; Dopamine; Basal Ganglia; Successor Representation; förstärkningsinlärning; dopamin; basala ganglierna; successionsrepresentation;

    Abstract : Accumulating evidence suggests that dopaminergic neurons show significant task-related diversity. Curiously, dopamine concentration and dopamine axon activity show spatio-temporal wave patterns in the dorsal striatum. READ MORE

  5. 4. OCD as behavioral addiction and the reward process : A systematic review

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Snezjana Budajeva; [2021]
    Keywords : Obsessive-compulsive disorder; reward; addiction;

    Abstract : Studies have shown that aberrant activity in some brain regions involved in the pathology of OCD overlaps similarly with individuals with addiction disorders. The reduced anxiety following a compulsion together with findings of diminished activation in the striatum during reward anticipation proposes a view of OCD being a behavior addiction. READ MORE

  6. 5. On the Existence of Functional Clusters in the Dorsomedial Striatum

    University essay from KTH/Optimeringslära och systemteori

    Author : Theodor Ohlsson; [2020]
    Keywords : ;

    Abstract : In recent years, the understanding of the brain has progressed immensely by advanced data gathering methods that can track the activity of individual neurons. This has enabled researchers to investigate the function and dynamics of different parts of the brain in detail. READ MORE
