  1. 6. Impact of using different brain layer amounts on the accuracy of Convolutional Neural networks trained on MR-Images to identify Parkinson's Disease

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

    Author : Benjamin Ronneling; Marcus Dypbukt Källman; [2021]
    Keywords : ;

    Abstract : Parkinson’s Disease (PD) is a neurodegenerative disease and brain disorder which affects the motor system and leads to shaking, stiffness, impaired balance and coordination. Diagnosing PD from Magnetic resonance images (MR-images) is difficult and often not possible for medical experts and therefore Convolutional neural networks (CNNs) are used instead. READ MORE

  3. 7. Low dimensional representations of neuronal activity in Parkinson’s disease

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

    Author : Gustav Röhss; Míriam Vall; [2020]
    Keywords : ;

    Abstract : This project has been concerned with developing methods for dimensionality reduction and feature extraction of brain activity in the basal ganglia in parkinsonian brains. Dimensionality reduction of local field potential activity was based on feature vectors produced from the discrete Fourier transform of activity. READ MORE

  4. 8. HIGH-FREQUENCY OSCILLATIONS IN A MOUSE MODEL OF PARKINSON’S DISEASE

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Love Zachrisson; [2020]
    Keywords : 6-OHDA; Parkinson s Disease; Basal Ganglia; LID; Gamma oscillation; 80Hz; HFO; Multichannel electrode array; Parkinsons sjukdom; 6-OHDA; LID; HFO; Gamma oscillering; 80Hz; Basala Ganglierna; Elektrodimplantat;

    Abstract : Dopamine replacement therapy is the main method of treating Parkinson’s Disease (PD), however over time this treatment causes increasingly abnormal, involuntary movements. This symptom, known as Levodopa-Induced-Dyskinesia (LID) is associated with aberrant, high frequency oscillations (HFOs) in the motor cortex and basal ganglia, as demonstrated with implanted electrodes in human Parkinson’s patients as well as in a rat model of Parkinson’s Disease.

  5. 9. Impulse response analysis of neuromodulation for the treatment of motor symptoms in Parkinson’s disease

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Staffan Hedström; [2016]
    Keywords : Technology and Engineering;

    Abstract : In adaptive deep brain stimulation, a treatment for motor symptoms in Parkinson’s disease, the target of the stimulus is usually in the sub-thalamic nucleus or the globus pallidus. In this thesis, a new stimulus target called reticular thalamus is investigated in a rat model of Parkinson’s disease. READ MORE

  6. 10. The effect of very light exercise on recognition memory in relation to attention ability

    University essay from Lunds universitet/Institutionen för psykologi

    Author : Hans Mikael Hagström; [2015]
    Keywords : basal ganglia; attention; exercise; moderate brain arousal; recognition memory; Social Sciences;

    Abstract : Moderate exercise is deemed beneficial for cognition due to increase in dopamine concentrations in the basal ganglia. Auditory white noise is beneficial for cognition, mainly for those with lower attentional ability, i.e. for those having lower tonic dopamine concentrations. READ MORE
