CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease. [PDF]
Ann Clin Transl NeurolABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

Thirty-Second Net Stressor Task in Adult Zebrafish
Bio-Protocol, 2015 Zebrafish have become a popular animal model for behavioral neuroscience (Gerlai, 2014). Recent studies have demonstrated that brief experimental handling prior to euthanizing animals can subsequently alter biological measures quantified post-mortem (e.g.
