  1. 1. Characterization of a Novel Tubular Carbon Fibre Based Electrode for Dopamine Detection with Fast Scan Cyclic Voltammetry

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sofia Hansson; [2022]
    Keywords : FSCV; Carbon Fibre Microelectrodes; Electrode development; Dopamine; Parkinson’s disease; In-vitro; FSCV; Kolfibermikroelektroder; Elektrodutveckling; Dopamin; Parkinsons sjukdom; In-vitro;

    Abstract : Fast Scan Cyclic Voltammetry (FSCV) is an electrochemical technique, based on ramping a voltage through a microelectrode and measuring the resulting redox current to obtain information about an electroactive molecule. FSCV can be used for the detection of dopamine, which is a vital neurotransmitter. READ MORE

  2. 2. 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

  3. 3. Feature Extraction and Classification of Medication-Induced Hyperkinesia During Treatment of Parkinson's Disease

    University essay from Lunds universitet/Matematisk statistik

    Author : Erik Liljeroth; [2020]
    Keywords : Parkinson s disease; neural network; autoencoder; classification; feature extraction; Mathematics and Statistics;

    Abstract : The recent progress in wearable sensor technology, signal processing and machine learning enables novel applications in fields such as automatic disease symptom tracking and classification. In this project, data from an ongoing Parkinson’s disease study at the Lund University Hospital is gathered and analyzed, and classification models of varying complexity for symptom severity are evaluated.

  4. 4. Correlation Transfer in Striatal Network via Morphology Changes

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

    Author : Lihao Guo; [2020]
    Keywords : ;

    Abstract : The activity of striatum is significantly modulated by dopamine, and long- term effects if an altered dopamine signalling can also lead to degeneration and regeneration of synapses. This thesis report investigates the signal transfer, especially correlation transfer, in the striatum. READ MORE

  5. 5. Modelling conversion of adult skin cells to neurons

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik; Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Viktor Drugge; [2018]
    Keywords : Human adult fibroblast; Neuron; Neural conversion; Transdifferentiation; Direct reprogramming; Direct lineage conversion; Simulation; Regulatory gene network; Gene network topology; Gene circuit; Gene dynamics; Physics and Astronomy;

    Abstract : Scientists are now able to directly convert one somatic cell type into another using a procedure known as direct lineage reprogramming or transdifferentiation. In this procedure, transcription factors which are important for initiating a rewriting of the gene expressions are introduced in the cell. READ MORE
