1. 1. Brain morphometry in Parkinson’s disease

   University essay from

   Author : Lönkvist Olivia; [2023-03-02]
   Keywords : Medical physics; Parkinson’s disease; Computational anatomy; Quantitative image analysis;

   Abstract : Abstract Purpose The purpose of this brain morphometry study was to examine the volumes of different regions of the brain by research participants with Parkinson’s disease. Method To carry out the study, MR (magnetic resonance) images from 956 research participants from the Parkinson’s Progression Markers Initiative (PPMI) were used. READ MORE

3. 2. Sex Differences in Dopamine D1-type Receptors and Episodic Memory : an Imaging Study Across the Adult Lifespan

   University essay from Umeå universitet/Umeå centrum för funktionell hjärnavbildning (UFBI); Umeå universitet/Institutionen för psykologi

   Author : Anton Degerfält; [2023]
   Keywords : dopamine; D1DR; sex; episodic memory; ageing; PET; MRI;

   Abstract : Identification of the pathways that could be targeted to alleviate ageing-related cognitive decline is of prime importance. One of the most promising target mechanisms is connected to healthy dopaminergic ageing. READ MORE

4. 3. Resting-state Functional Connectivity in Anhedonia: Exploring the Effects of Pramipexole

   University essay from Lunds universitet/Institutionen för psykologi

   Author : Frida Smids; [2023]
   Keywords : Anhedonia; Depression; Reward; Pramipexole; Resting-state; Functional Connectivity; Nucleus Accumbens; Social Sciences;

   Abstract : Pramipexole is a medication that normalises dopamine signalling in the brain. Previous studies have suggested that pramipexole is an effective treatment option for depression and anhedonia because it targets the dopaminergic pathways within the brain’s reward network. READ MORE

5. 4. 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.

6. 5. 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
