Unilateral hypertrophy of the tensor fasciae latae (TFL) is an uncommon radiologic finding that may present as a palpable soft tissue mass in thigh. Accurate diagnosis can circumvent unnecessary biopsy for this benign finding. We report two cases unilateral muscles, both which presented proximal thigh mass. provide examples sonographic, computed tomography (CT), and magnetic resonance imaging (...

Monocular deprivation (MD) is a well-known paradigm of experience-dependent plasticity in which cortical neurons exhibit a shift of ocular dominance (OD) toward the open eye. The mechanisms underlying this form of plasticity are incompletely understood. Here we demonstrate the involvement of callosal connections in the synaptic modifications occurring during MD. Rats at the peak of the critical...

Monocular deprivation (MD) during the critical period (CP) shifts ocular dominance (OD) of cortical responsiveness toward the nondeprived eye. The synaptic mechanisms underlying MD-induced OD plasticity, in particular the contribution of cortical inhibition to the plasticity, have remained unsolved. In this study, using in vivo whole-cell voltage-clamp recordings, we revealed eye-specific excit...

Zebrafish are a proven model for vision research, however many of the earlier methods generally focused on larval fish or demonstrated a simple response. More recently adult visual behavior in zebrafish has become of interest, but methods to measure specific responses are new coming. To address this gap, we set out to develop a methodology to repeatedly and accurately utilize the optokinetic re...

The visual system can adapt to optical blur, whereby the adapted image is perceived as sharp. Here we show that adaptation reduces blur-induced biases in shape perception, with repeated adaptations (perceptual learning), leading to unbiased perception upon re-exposure to blur. Observers wore a cylindrical lens of +1.00 D on one eye, thus simulating monocular astigmatism. The other eye was eithe...

Recent electrophysiological studies of rodent visual cortex suggest that, in addition to deprived-eye depression, monocular deprivation (MD) also shifts ocular dominance by potentiation of open-eye responses. We used computer-based, two-choice discrimination tasks to assess the behavioral significance of these findings in rats. As expected, prolonged MD, from postnatal day 21 until adulthood (>...

Syringoma is a benign tumor arising from intra-epidermal ducts of eccrine sweat glands. It usually presents as small translucent papules on eyelids and upper cheeks. The case, which is presented, is a rare from of syringoma that occurred in a linear fashion on the trunk. Dermatologists should be aware of such form of syringoma to differentiate it from other similar lesions. This 23 year-o...
