Cholinergic signalling is critically involved in learning and memory processes in the hippocampus, but the postsynaptic impact of cholinergic modulation on morphologically defined subtypes of hippocampal interneurones remains unclear. We investigated the influence of muscarinic receptor (mAChR) activation on stratum oriens interneurones using whole-cell(More)
The M-current (I(M)), comprised of Kv7 channels, is a voltage-activated K+ conductance that plays a key role in the control of cell excitability. In hippocampal principal cells, I(M) controls action potential (AP) accommodation and contributes to the medium-duration afterhyperpolarization, but the role of I(M) in control of interneuron excitability remains(More)
Cholinergic activation of hippocampal targets can initiate and sustain network oscillations in vivo and in vitro, yet the impact of cholinergic modulation on the oscillatory properties of interneurones remains virtually unexplored. Using whole cell current clamp recordings in acute hippocampal slices, we investigated the influence of muscarinic receptor(More)
Amyotrophic lateral sclerosis (ALS), a rapidly progressive, invariably fatal disease, involves mixed upper and lower motor neurons in different spinal cord regions. Patients with bulbar onset progress more rapidly than patients with limb onset or with a lower motor neuron presentation. Recent descriptions of regional variants suggest some patients have ALS(More)
Sporadic inclusion body myositis (sIBM) is the commonest severe myopathy in patients more than 50 years of age. Previous therapeutic trials have targeted the inflammatory features of sIBM but all have failed. Because protein dyshomeostasis may also play a role in sIBM, we tested the effects of targeting this feature of the disease. Using rat myoblast(More)
OBJECTIVE To determine identifiable subgroups of patients with primary lateral sclerosis (PLS) with distinct clinical features as a first step in identifying patients likely to have the same disorder. METHODS Twenty-five patients meeting previously proposed diagnostic criteria for PLS were seen for examination, measurement of gait and finger tapping(More)
PURPOSE OF REVIEW Recent advances have provided a model for understanding the underlying molecular genetic changes in facioscapulohumeral muscular dystrophy (FSHD). This review will highlight our current understanding and future research directions. RECENT FINDINGS FSHD typically results from contraction of a critical number of D4Z4 repeats in a(More)
Primary lateral sclerosis is characterized by insidious onset of progressive upper motor neuron dysfunction in the absence of clinical signs of lower motor neuron involvement. Patients experience stiffness; decreased balance and coordination; mild weakness; and, if the bulbar region is affected, difficulty speaking and swallowing, and emotional lability.(More)
INTRODUCTION In preparation for future clinical trials, we determined the reliability, relationship to measures of disease severity, and consistency across sites of the 6 Minute Walk Test (6MWT) in patients with facioscapulohumeral muscular dystrophy (FSHD). METHODS Genetically defined and clinically affected FSHD participants at 2 sites performed the(More)
Recent advances in the understanding of the molecular pathophysiology of facioscapulohumeral muscular dystrophy (FSHD) have identified potential therapeutic targets. Consequently, an accurate understanding of disease progression in FSHD is crucial for the design of future clinical trials. Data from 228 subjects in 3 clinical trials and 1 natural history(More)
