Intuitively, dynamic visual stimuli, such as moving objects or flashing lights, attract attention. Visual search tasks have revealed that dynamic targets among static distractors can indeed efficiently guide attention. The present study shows that the reverse case, a static target among dynamic distractors, allows for relatively efficient selection in certain but not all cases. A static target ...

Neurosarcoidosis is a rare manifestation of sarcoidosis, comprising 5-15% cases. We present case 44-year-old man with no prior medical history who experienced two episodes diffuse tonic-clonic seizures. Imaging showed dural-based lesion evidence brain parenchymal involvement, suggestive an aggressive, atypical meningioma invasion. He underwent resection and recovered well; histopathological ass...

The temporal interval between flashing lights that is required to perceive nonsimultaneity decreases as the refractive error increases from 0 to +2 diopters. The interval then remains constant with further increases to 3 and 4 diopters. The results are discussed in terms of the relative increase of transient to sustained visual channels and of the increase in apparent movement.

Orofacial pain' most commonly occurs due to dental causes like caries, gingivitis or periodontitis. Other common causes of 'orofacial pain' are sinusitis, temporomandibular joint(TMJ) dysfunction, otitis externa, tension headache and migraine. In some patients, the etiology of 'orofacial pain' remains undetected despite optimal evaluation. A few patients in the practice of clinical dentistry pr...

Epidermal cysts are benign tumors commonly known as sebaceous cyst and frequently found throughout the body. These lined with true, stratified-Squamous epithelium, derived from hair follicle. They can grow of any size maybe get infected over a period time. is usually asymptomatic mostly presents slowly growing painless mass. most confused other like dermoid but histopathological examination pro...
