Exploration of the space around us is a fundamental part of human behaviour. When it breaks down there is an important opportunity to understand its underlying mechanisms. Here we show that many right-hemisphere patients with left neglect re-explore rightward locations, failing to keep track of them during search. Importantly, such re-exploration occurred(More)
BACKGROUND Noninvasive cortical stimulation could represent an add-on treatment to enhance motor recovery after stroke. However, its clinical value, including anticipated size and duration of the treatment effects, remains largely unknown. OBJECTIVE The authors designed a small semi-randomized clinical trial to explore whether long-lasting clinically(More)
Ten affected individuals are described from a kindred with autosomal dominant familial Alzheimer's disease in which a mutation in the amyloid precursor protein gene results in a valine to glycine substitution at amyloid precursor protein 717 which co-segregates with the disease. The mean age at onset of symptoms was 52 years with a range from 40 years to 67(More)
A 50 year old woman developed progressive encephalomyelitis with rigidity over a three year period. Her CSF contained oligoclonal bands and both her serum and CSF contained antibodies directed against GABA-ergic synapses (antiglutamic acid decarboxylase [corrected] antibodies). These antibodies have recently been described in cases of stiff man syndrome.(More)

If you want to objectively quantify the level of sedation the intuitive solution must be to monitor the brain directly. However, due to the complexity of this organ, and our limited understanding of consciousness, this remains a daunting challenge. For many years, researchers have investigated the electrical activity of the brain and its relationship with(More)
A 64-year-old British Caucasian man presented with red skin wheals and breathlessness and then developed a progressive neurological syndrome. Investigation revealed hereditary haemachromatosis, porphyria, and a myelodysplastic syndrome. No unifying diagnosis was made, and his neurological symptoms remained unexplained, until further studies revealed an(More)
Becker muscular dystrophy may be associated with myocardial abnormalities which are usually diagnosed after the onset of weakness. We present a patient who developed complete heart block 6 years before the onset of muscle weakness which occurred unusually late at the age of 62 years.
