The ADAM binary neural network which has been used for image analysis applications, is con-tructed around a central component termed a Correlation Matrix Memory (CMM). A recent re-examination of the CMM has led to development of the Advanced Uncertain Reasoning Architecture (AURA). AURA inherits many useful characteristics from ADAM, but is intended for applications requiring the manipulation o...

We established a conditional deletion of Aurora A kinase (AurA) in Cdk1 analogue-sensitive DT40 cells to analyze AurA knockout phenotypes after Cdk1 activation. In the absence of AurA, cells form bipolar spindles but fail to properly align their chromosomes and exit mitosis with segregation errors. The resulting daughter cells exhibit a variety of phenotypes and are highly aneuploid. Aurora B k...

UNLABELLED Migraine is a central nervous system disorder frequently expressed with paroxysmal visual dysfunctions. OBJECTIVE To test the hypothesis that normal visual input is vital for the migrainous aura and photophobia. METHOD We studied the migraine-related visual disturbances in 8 sightless migraineurs identified among 200 visually impaired subjects. RESULTS The main findings were th...

Atypical features of hemicrania continua (HC), including both visual aura and side shifting, have been reported previously. However, auras and variable unilaterality have never been reported together in HC. We report two patients with side-shifting HC with aura. These patients' symptoms are unilateral headaches, visual aura, autonomic features, throbbing pain, nausea and photo/phonophobia. One ...

OBJECTIVE To determine if migraineurs with aura respond differently to biofeedback/relaxation than those without aura and, if so, whether the variability in outcome can be explained by blood flow velocity. Background.-The relationship between cerebral blood flow velocity and treatment response to biofeedback/relaxation in migraine with and without aura is uncertain. METHOD Twenty migraineurs ...

OBJECTIVE To examine the association between a lifetime history of migraines and other headaches with and without aura and Rose angina and coronary heart disease (CHD). METHODS Participants were 12,409 African American and white men and women from the Atherosclerosis Risk in Communities Study, categorized by their lifetime history of headaches lasting > or =4 hours (migraine with aura, migrai...

BACKGROUND Migraine aura may be difficult to differentiate from transient ischemic attacks and other transient neurological disorders in pregnant women. The aims of the present study were to investigate and diagnose all pregnant women with transient neurological disorders of suspected central nervous system origin, and to compare this group with a control group of pregnant women with regard to ...

OBJECTIVE We evaluated the current evidence on the association between migraine, including aura status, and cervical artery dissection. METHODS We performed a systematic review and meta-analysis of studies investigating the association between migraine or migraine subtypes (e.g. migraine with aura) and cervical artery dissection published through October 2010. RESULTS We identified five cas...

BACKGROUND AND PURPOSE Silent ischemic brain lesions frequently occur in migraine with aura and are most often located in cerebellar border zones. This may imply an impairment of cerebellar blood flow autoregulation. This study investigated the characteristics of interictal cerebellar autoregulation in migraine with and without aura. METHODS Thirty-four patients (n=17, migraine without aura; ...
