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

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. The positive effect of exercise on mood, as a non-motor symptom, in Parkinson's disease

    Kandidat-uppsats, Uppsala universitet/Institutionen för organismbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Marina Sammils Baleiro; [2021]
    Nyckelord :parkinson s disease; parkinson s; mood; depression; anxiety; apathy; exercise;

    Sammanfattning : Parkinson’s Disease is a degenerative neurological disease where dopaminergic neurons in the basal ganglia degenerate and die. This leads to dopamine deficiency in the basal ganglia, affecting both motor and non-motor systems, giving both motor and non-motor symptoms. LÄS MER

  4. 3. Non-motor symptoms and their use as markers for prodromal and early Parkinson's disease

    Kandidat-uppsats, Uppsala universitet/Institutionen för organismbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Aubree Stephens; [2021]
    Nyckelord :Neurology; Parkinson s; non-motor symptom; prodromal;

    Sammanfattning : Parkinson’s Disease (PD) is the second most common neurodegenerative disorder. It is a disease with a broad spectrum of symptoms, both motor and non-motor, but is often only diagnosed when the motor symptoms begin to appear. LÄS MER

  5. 4. The subthalamic nucleus in health and disease

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Yu Zhang; [2020]
    Nyckelord :;

    Sammanfattning : Parkinson’s disease (PD) is the second most common neurodegenerative disorder in the world. PD is caused by degeneration of the dopaminergic neurons in the substantia nigra pars compacta (SNc). LÄS MER

  7. 5. THE NEURODEGENERATION PROCESS IN THE STRIATUM OF MICE EXPOSED TO OBESOGENIC DIETS

    Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Ankita Talukdar; [2020]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Obesity and diabetes are known to impact brain function and alter metabolism. Studies in rodents show that consumption of high fat and high sugar diets lead to brain dysfunction affecting memory and cognition, and increases risk of cerebro-vascular and neurodegenerative disorders.
