A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

Red nucleus and rubrospinal tract disorganization in the absence of Pou4f1

open access: yesFrontiers in Neuroanatomy, 2015
The red nucleus is a neuronal population that plays an important role in forelimb motor control and locomotion. Histologically it is subdivided into two subpopulations, the parvocellular red nucleus located in the diencephalon and the magnocellular red ...

The Dopaminergic Midbrain Encodes the Expected Certainty about Desired Outcomes [PDF]

open access: yes, 2014
Dopamine plays a key role in learning; however, its exact function in decision making and choice remains unclear. Recently, we proposed a generic model based on active (Bayesian) inference wherein dopamine encodes the precision of beliefs about optimal ...

Pains, gains, and midbrains [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
One of the main aims of neuroscience is to understand how the CNS deals with and adapts to external inputs and internal events. The altered molecular and cellular events form a basis for abnormal processing that underlies physiopathological events. Understanding these events can allow translation from bench science to the patient, and a key step in ...

CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT 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.

Unique case of midbrain tuberculoma presenting as isolated inferior rectus palsy with nystagmus

open access: yesIndian Journal of Ophthalmology, 2018
Isolated brain stem tuberculoma constitutes about 5% of all intracranial tuberculomas. A case of isolated inferior rectus palsy with downbeat nystagmus due to presumed midbrain tuberculoma in an immunocompetent patient is described here.

Diesel Exhaust Activates & Primes Microglia: Air Pollution, Neuroinflammation, & Regulation of Dopaminergic Neurotoxicity [PDF]

open access: yes, 2011
BACKGROUND: Air pollution is linked to central nervous system disease, but the mechanisms responsible are poorly understood. OBJECTIVES: Here, we sought to address the brain-region-specific effects of diesel exhaust (DE) and key cellular mechanisms ...
