Background. Brain lesions may influence their border zones by moving, compressing, infiltration, edema or by a mixture of all the above. Sources of evoked and spontaneous activity in border zones can be localized by the MEG. Methods. The inherent multisource problem can be handled by using spatial average techniques (Dipole-Density-Plot (DDP) and Current-Density-Plot (CDP)). The reliability was...

A new version of craniocorpography (CCG), called computerized ultrasonographic CCG (Comp-USCCG), has been clinically applied for objective recording, documentation, and quantitative evaluation of abnormal psychomotor activity in psychiatric patients. Implications of this completely new approach to psychopathology are discussed. An original representation of Comp-USCCG data (introducing the time...

In this paper we introduce an unsupervised online clustering algorithm to detect abnormal activities using mobile devices. This algorithm constantly monitors a user’s daily routine and builds his/her personal behavior model through online clustering. When the system observes activities that do not belong to any known normal activities, it immediately generates alert signals so that incidents ca...

Detecting abnormal activities from sensor readings is an important research problem in activity recognition. A number of different algorithms have been proposed in the past to tackle this problem. Many of the previous state-based approaches suffer from the problem of failing to decide the appropriate number of states, which are difficult to find through a trial-and-error approach, in real-world...

Central pain syndrome (CPS) is a debilitating and chronic pain condition that results from a lesion or dysfunction in the CNS. The pathophysiological mechanisms underlying CPS are poorly understood. We recently demonstrated that CPS is associated with suppressed inputs from the inhibitory nucleus zona incerta to the posterior thalamus (PO). As a consequence, activity in PO is abnormally increas...

Schwann cells in the peripheral nervous systems extend their membranes to wrap axons concentrically and form the insulating sheath, called myelin. The spaces between layers of myelin are sealed by myelin junctions. This tight insulation enables rapid conduction of electric impulses (action potentials) through axons. Demyelination (stripping off the insulating sheath) has been widely regarded as...

Activation of matrix metalloproteinases (MMPs) in the heart is known to facilitate cardiac remodeling and progression to failure. We hypothesized that regional dyskinetic wall motion of the left ventricle would stimulate activation of MMPs. Abnormal wall motion at a target site on the anterior lateral wall of the left ventricle was induced by pacing atrial and ventricular sites of five open-che...

Pallidotomy was performed in a parkinsonian patient with off-period foot dystonia. Dystonia appeared at the beginning of surgery and disappeared after the first microelectrode penetration of the globus pallidus, perhaps a micropallidotomy effect. Neuronal recording during dystonia revealed that the mean firing rates were low in both the internal and external segments of the globus pallidus, and...

A vibrant branch of research in computer vision that has attracted a lot of attention for decades is the human activity understanding from video. A means for accurately locating humans in image or a video is a prerequisite to the process of understanding human activities or action. This work’s focus is on investigating the use of people detectors for video surveillance in Financial Banks premis...
