Speed and accuracy in a visual motion discrimination task as performed by rats [PDF]

open access: yesarXiv, 2012
We find that rats, like primates and humans, perform better on the random dot motion task when they take more time to respond. We provide evidence that this improvement is due to stimulus integration. Rats increase their response latency modestly as a function of trial difficulty.

Twelve‐month change in quantitative MRI calf muscle fat fraction in CMT1A predicts clinical change over 4 years

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective We measured clinical and quantitative MRI outcome measures in CMT1A to assess long‐term responsiveness, establish longitudinal validity and assess MRI as a bridging biomarker. Methods Twenty patients with CMT1A and 20 matched controls underwent MRI, myometry and clinical assessments up to four times over mean 4‐year follow‐up ...

History of Neuroscience: Mesoglia and Microglia [PDF]

open access: yes, 2007
Microglia are mononuclear phagocytes that reside within the central nervous system (CNS). They differ from macroglia (astrocytes and oligodendrocytes) in terms of their origin, phenotype and functions, but more closely resemble tissue-resident ...

Clinical impact and safety of brain biopsy in unexplained central nervous system disorders: a real‐world cohort study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective A substantial part of central nervous system (CNS) disorders remains unexplained, despite various new and minimally invasive diagnostic techniques. Within this rapidly developing diagnostic field, the precise role of brain biopsy is unknown.

ALS plasma biomarkers reveal neurofilament and pTau correlate with disease onset and progression

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective We performed a pilot screen to assess the utility of the NULISA™ (Nucleic‐acid‐Linked Immuno‐Sandwich Assay) platform in the identification of amyotrophic lateral sclerosis (ALS) biomarkers. Methods Plasma from 86 individuals (48 ALS, 18 asymptomatic C9orf72 repeat expansion carriers (AsymC9), and 20 healthy controls) was analyzed ...
