PET tracers for imaging of the dopaminergic system.

The dopaminergic system plays a major role in neurological and psychiatric disorders such as Parkinson's disease, Huntington's disease, tardive dyskinea and schizophrenia. Knowledge on altered dopamine synthesis, receptor densities and status are important for understanding the mechanisms underlying the pathogenesis and therapy of diseases. PET provides a non-invasive tool to investigate these ...

Dopaminergic System in Linguistic Comprehension and Grammar: fMRI study of Parkinsons Disease

This objective of this study is how grammar is implemented in the brain, with special attention to a neurotransmitter dopamine. Among numerous kinds of molecules known to exist in the nervous system, several molecules are known to function as “neurotransmitters”, which mediate gaps between neurons (i.e., synapses) when a neuron transmits signals to another. In this study, a neurotransmitter dop...

The molecular basis of dopaminergic brain imaging in Parkinson's disease.

The central role of dopamine neuronal loss in Parkinson's disease provides a clear pathologic framework and rationale for imaging the system both to interrogate dynamic pathophysiologic changes as well as to aid in diagnosis and clinical management. Recent post mortem studies of Parkinson's brain provide a much fuller depiction of the inexorable and progressive topology of pathophysiologic chan...

Molecular Imaging of Alzheimer’s Disease Using PET

Molecular Imaging Techniques Molecular imaging of the brain aims to quantify various biological processes via the modeling of interactions between a molecular probe and a molecule of interest naturally occurring in a living organism. Brain molecular-imaging techniques such as positron emission tomography (PET) and single photon emission tomography (SPECT) allow clinical investigators to record ...

Imaging beyond the striatonigral dopaminergic system in Parkinson's disease.

Parkinson 's disease (PD) is characterized by progressive loss of dopaminergic neurons in the nigrostriatal pathway, but this seems to constitute only part of the whole pathological process of the disease. Accumulating data have documented the concomitant degeneration of other dopaminergic pathways and of the serotonergic, cholinergic and noradrenergic neurotransmitter systems. In addition,...
