Here we describe a method for measuring tonotopic maps and estimating bandwidth for voxels in human primary auditory cortex (PAC) using a modification of the population Receptive Field (pRF) model, developed for retinotopic mapping in visual cortex by Dumoulin and Wandell (2008). The pRF method reliably estimates tonotopic maps in the presence of acoustic scanner noise, and has two advantages o...
Does Congenital Deafness Affect the Structural and Functional Architecture of Primary Visual Cortex?
Deafness results in greater reliance on the remaining senses. It is unknown whether the cortical architecture of the intact senses is optimized to compensate for lost input. Here we performed widefield population receptive field (pRF) mapping of primary visual cortex (V1) with functional magnetic resonance imaging (fMRI) in hearing and congenitally deaf participants, all of whom had learnt sign...
OBJECTIVE To investigate the comparative treatment effects of ultrasound-guided pulsed radiofrequency treatment (UG-PRF) in the gastrocnemius interfascial space and ultrasound-guided interfascial injection (UG-INJ) on myofascial pain syndrome. METHODS Forty consecutive patients with myofascial pain syndrome of the gastrocnemius were enrolled and were allocated to one of the two groups. Twenty...
رادارهایی که از prf متوسط استفاده می کنند هردو ابهام برد و داپلر را دارند ولی با انتخاب یک دسته prf، می توان این ابهام ها را برطرف کرد. دو نکته ی مهم که باید در آشکارسازی هدف مدنظر قرار داد، پرهیز از آشکارشدن شبه هدف و حداقل کردن مناطق کوری که باعث آشکار نشدن اهداف می شوند است. در این رساله، از الگوریتم ژنتیک برای انتخاب دسته prf به منظور حداقل کردن مناطق کور استفاده شده است. سپس از همین دسته ا...
We developed a new product called titanium-prepared platelet-rich fibrin (T-PRF). The T-PRF method is based on the hypothesis that titanium may be more effective in activating platelets than the silica activators used with glass tubes in Chouckroun's leukocyte- and platelet-rich fibrin (L-PRF) method. In this study, we aimed to define the structural characteristics of T-PRF and compare it with ...
Platelet-rich fibrin (PRF) has a lot of benefits in the process healing. The new generation PRF, namely advanced PRF plus (A-PRF+), different structure and more growth factors compared to Advanced (A-PRF), before A-PRF+. Objectives:To effects A-PRF A-PRF+ on IIB degree burn. Methods: This experimental study used 20 male Sprague Dawley rats. All rats were given burn divided into four groups. Gro...
Experiments to identify the knock trends of lean gasoline-air mixtures, and such mixtures enhanced with hydrogen (H2) and carbon monoxide (CO), were performed on a single-cylinder research engine with boosting capability. The experimental method used to investigate knock trends consisted of determining the octane number (ON) of the primary reference fuel (mixture of isooctane and n-heptane) sup...
Introduction: Platelet-rich fibrin (PRF) naturally derived second generation of platelet concentrates, which has gained increasing awareness in recent years for regenerative procedures. This biologic additive is completely autologous, easy to prepare, minimal expense, and possesses prolonged growth factor release, together with several other advantages over traditionally prepared concentrates. ...
Visual cortex is retinotopically organized so that neighboring populations of cells map to neighboring parts of the visual field. Functional magnetic resonance imaging allows us to estimate voxel-based population receptive fields (pRF), i.e., the part of the visual field that activates the cells within each voxel. Prior, direct, pRF estimation methods(1) suffer from certain limitations: 1) the ...
