Theta oscillations are essential for learning and memory, their generation requires GABAergic interneurons. To better understand how theta is generated, we explored parvalbumin (PV) somatostatin (SOM) interneurons in CA1 stratum oriens/alveus fire during hippocampal investigated synaptic mechanisms underlying behavior. Combining the use of transgenic mice to visually identify PV SOM intact preparation that can generate vitro without cholinergic agonists, performed simultaneous field...
Study of the neural deficits caused by mismatched binocular vision in early childhood has predominantly focused on circuits primary visual cortex (V1). Recent evidence revealed that neurons mouse dorsolateral geniculate nucleus (dLGN) can undergo rapid ocular dominance plasticity following monocular deprivation (MD). It remains unclear, however, whether long-lasting attributed to MD during critical period originate thalamus. Using vivo two-photon Ca 2+ imaging dLGN afferents superficial...
Study Design. An electromyogram procedure using spectral parameters to distinguish subjects with low back pain from those without. Objectives. To add the growing database on this procedure, assess possible overfitting of data in classification model, determine whether a model based contraction level 60% maximum voluntary can produce concordance rates similar models 40% and 80% contraction, develop Summary Background Data. Other investigators have published series which measured during...
Despite the recent emergence of multiple cellular and molecular strategies to restore vision in retinal disorders, it remains unclear what extent central visual circuits can recover when defects are corrected adulthood. We addressed this question an Lrat-/- mouse model Leber congenital amaurosis (LCA) which light sensitivity optomotor responses partially restored by 9-cis-retinyl acetate administration Following treatment, two-photon calcium imaging revealed increases number response...
Many businesses and consumers are extending the capabilities of voice-based services such as Amazon Alexa, Google Home, Microsoft Cortana, Apple Siri to create custom voice experiences (also known skills). As number these increases, a key problem is discovery skills that can be used address user's request. In this paper, we focus on conversational skill present agent which engages in dialog with users help them find fulfill their needs. To end, start rule-based improve it by using...
Abstract In the present study, we report on an experimental technique which enables three-dimensional imaging and reconstruction of microfluidic mixing surface — entire flow volume at a 90° branch formed between converging Newtonian fluids differing rate viscosity. Only steady-state flows are examined. The involves use dual-channel laser scanning confocal microscopy (LSCM) represents significant extension previously introduced by Hitt & Lowe [1].
An electromyographic (EMG) analysis of eight leg muscles when riding a stepper bike at various workloads in both the seated and standing positions is presented.
ABSTRACT Monocular deprivation (MD) during the juvenile critical period leads to long-lasting impairments in binocular function and visual acuity. The site of these changes has been widely considered be cortical. However, recent evidence indicates that integration may first occur dorsolateral geniculate nucleus thalamus (dLGN), raising question whether MD produce deficits dLGN integration. Using vivo two-photon Ca 2+ imaging afferents excitatory neurons superficial layers primary cortex...
Recently a computer-controlled scanning ultrasound imaging system was developed in our laboratory. It includes pair of broadband 48-MHz focusing copolymer transducers. The apertures the transducers and their f-numbers were identically equal to 2 mm 2.25, respectively. A specimen can be moved 10-μm increment its plane normal direction rotated along propagation direction. used produce transmission-mode shear-wave as well longitudinal-wave images solid specimens. Shear waves solids generated by...
