Multiple system atrophy (MSA) is a rare neurodegenerative disease of undetermined cause manifesting with progressive autonomic failure (AF), cerebellar ataxia and parkinsonism due to neuronal loss in multiple brain areas associated with (oligodendro)glial cytoplasmic alpha-synuclein (alpha SYN) inclusions (GCIs). Using proteolipid protein (PLP)-alpha-synuclein (alpha SYN) transgenic mice we hav...
Objective(s): Nitric oxide (NO) is an important neurotransmitter in central nervous system involved in central cardiovascular regulation. The presence of NO in the pedunculopontine tegmental (PPT) nucleus has been shown, but its cardiovascular effect has not been determined. In the present study, the cardiovascular effect of NO in the PPT nucleus was evaluated. Materials and Methods: After indu...
Gait freezing is an episodic arrest of locomotion due to an inability to take normal steps. Pedunculopontine nucleus stimulation is an emerging therapy proposed to improve gait freezing, even where refractory to medication. However, the efficacy and precise effects of pedunculopontine nucleus stimulation on Parkinsonian gait disturbance are not established. The clinical application of this new ...
Phasic firing of dopamine (DA) neurons in the ventral tegmental area (VTA) and substantia nigra (SN) is likely to be crucial for reward processing that guides learning. One of the key structures implicated in the regulation of this DA burst firing is the pedunculopontine tegmental nucleus (PPTg), which projects to both the VTA and SN. Different literatures suggest that the PPTg serves as a sens...
The pedunculopontine nucleus, a component of the reticular formation, is topographically organized in animal models and implicated in locomotor control. In Parkinson's disease, pedunculopontine nucleus stimulation is an emerging treatment for gait freezing. Local field potentials recorded from pedunculopontine nucleus electrodes in such patients have demonstrated oscillations in the alpha and b...
