There are approximately 1,000 genes involved in odor recognition and 347 that code for functional receptors. This enables our distinguishing of approximately 4,000–10,000 distinct odorous ligands, a scientific discovery that earned a Nobel Prize in 2004.1 The olfactory nerve (CN1) contains 6–10 million receptor cells whose ciliated dendrites and cell bodies are contained within a specialized (neuro)epithelium located within the posterior nasal cavity (figure).… Read More...

Abstract
Objective: To assess whether concussion in childhood or adolescence is associated with subsequent multiple sclerosis risk. Previous research suggests an association but methodological limitations included retrospective data collection and small study populations.
Methods: The national Swedish Patient (hospital diagnoses) and Multiple Sclerosis registers were used to identify all MS diagnoses up to 2012 among people born from 1964, when the Patient Register was established.… Read More...

Abstract
Decreasing biomedical research support over the past decade has driven many talented young scientists to seek careers outside academia. In 2011, the Department of Neurology at Johns Hopkins University School of Medicine developed an internal grant review program (IGRP) to systematically review career development awards (CDAs) and research grants (e.g., R01s) for junior investigators prior to NIH submission.… Read More...

Abstract
Objectives: To characterize neurophysiological subcortical abnormalities in myoclonus-dystonia and their modulation by alcohol administration.
Methods: Cerebellar associative learning and basal ganglia-brainstem interaction were investigated in 17 myoclonus-dystonia patients with epsilon-sarcoglycan (SGCE) gene mutation and 21 age- and sex-matched healthy controls by means of classical eyeblink conditioning and blink reflex recovery cycle before and after alcohol intake resulting in a breath alcohol concentration of 0.08% (0.8 g/l).… Read More...

Objective

Find the optimal continuous electroencephalographic (CEEG) monitoring duration for seizure detection in critically ill patients.

Methods

We analyzed prospective data from 665 consecutive CEEGs, including clinical factors and time-to-event emergence of electroencephalographic (EEG) findings over 72 hours. Clinical factors were selected using logistic regression.

Objective

The cause of mesial temporal lobe epilepsy (MTLE) is often unknown. We ascertained to what extent newly diagnosed nonlesional MTLE actually represents familial MTLE (FMTLE).

Methods

We identified all consecutive patients presenting to the Austin Health First Seizure Clinic with MTLE and normal magnetic resonance imaging (MRI) or MRI evidence of hippocampal sclerosis over a 10-year period.

Objective

To characterize cerebral microbleeds (CMBs) in lacunar stroke patients in the Secondary Prevention of Small Subcortical Strokes (SPS3) trial and to assess their relationship with recurrent stroke and death, and response to assigned treatment.

Methods

SPS3 is a randomized, clinical trial conducted between 2003 and 2011.
