Functions of GluN2D-containing NMDA receptors in dopamine neurons of the substantia nigra pars compacta
… neurons of the substantia nigra pars compacta (SNc) have a key role in regulation of voluntary movement control. Their death is a hallmark of Parkinson’s disease, characterised by inhibited motor control, including muscle rigidity and tremor. Excitatory input to SNc-DA neurons is primarily from …

Differential Effects of Parkinsonian Toxins and L-DOPA on Locus Coeruleus and Substantia Nigra Neurons: Implications for Parkinson’s Disease
… neurons of the Substantia Nigra pars compacta (SNc). However, PD patients also suffer from many non-motor symptoms (NMS; eg. sleep disturbance, autonomic dysfunction, depression and anxiety), which cause significant disability and impair quality of life. These NMS often occur many years before …

Cognition in healthy aging and Parkinson's disease : structural and functional integrity of neural circuits
… dopaminergic substantia nigra, pars compacta (SNc). Cognitive sequelae of PD, however, likely result from disruptions in multiple neurotransmitter systems, including nondopaminergic nuclei, but research on these aspects of the disease has been hindered by a lack of sensitive MRI biomarkers for …

Do Rats Consume Ethanol to Regulate a Negative Emotion Induced by a Successive Negative Contrast Procedure?
… consumption of alcohol. I used successive (SNC) and anticipatory negative contrast (ANC) procedures to further examine this hypothesis and the previous findings (Manzo et al., 2015), that rats increase consumption and preference for ethanol in post-shift sessions of a SNC procedure. The …

Marcadores periféricos de dano ao sistema nervoso central : a proteína S100B e atividades ecto-nucleotidásicas
… intensidade do dano ao sistema nervoso central (SNC) o que permite sua utilização em estudos como marcador bioquímico de dano ou disfunção cerebral. Esta tese está dividida em três partes. A primeira parte propõe a utilização clínica da proteína S100B em patologias com envolvimento do SNC como a …

Evaluating Sex and Line Differences in Successive Negative Contrast and Ethanol Consumption Using Alcohol Preferring and High Alcohol Drinking Rats
… a consummatory successive negative contrast (SNC) procedure to demonstrate unexpected reward loss reactivity in two lines selectively bred to consume high amounts of ethanol, alcohol preferring (P) and high alcohol drinking (HAD) rats. Following this reward loss, animals were given free access …
