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...
متن کاملThe Study of Serum Asymmetric Dimethylarginine Concentrations in the Different Paraoxonase Phenotypes of Exudative Age-related Macular Degeneration Disease
Background and Aims: Age-related macular degeneration (ARMD) is a degenerative retinal disorder that causes progressive loss of central vision in older adults. The study aimed to determine the effect of asymmetric dimethylarginine (ADMA) as oxidizing metabolite and paraoxonase (PON1) activity within its phenotypes as an antioxidant agent in the development of such multifactorial disease. Mater...
متن کاملBrain angiotensin and dopaminergic degeneration: relevance to Parkinson's disease.
The pathogenic mechanism of Parkinson's disease (PD) appears to be multifactorial. However, oxidative stress and neuroinflammation, including activation of NADPH-dependent oxidases, play a major role in the progression of dopaminergic cell death. The renin-angiotensin system (RAS) was described as a circulating humoral system that regulates blood pressure and water homeostasis. However, there e...
متن کاملAsymmetric dopaminergic degeneration and levodopa alter functional corticostriatal connectivity bilaterally in experimental parkinsonism
Asymmetric dopamine loss is commonly found in early Parkinson's disease (PD), but its effects on functional networks have been difficult to delineate in PD patients because of variations in age, disease duration and therapy. Here we used unilateral 6-hydroxydopamine-lesioned (6-OHDA) rats and controls and treated them with a single intraperitoneal injection of levodopa (L-DOPA) before performin...
متن کاملAttentional control and asymmetric associative priming.
Participants completed a battery of 3 attentional control (AC) tasks (OSPAN, antisaccade, and Stroop, as in Hutchison, 2007) and performed a lexical decision task with symmetrically associated (e.g., sister-brother) and asymmetrically related primes and targets presented in both the forward (e.g., atom-bomb) and backward (e.g., fire-blaze) directions at either a 250- or 1,250-ms stimulus onset ...
