Published: January 2014
In this article, we first review some aspects of functional magnetic resonance imaging (fMRI) paradigm designing for major cognitive functions by using stimulus delivery systems like Cogent, E-Prime, Presentation, etc., along with their technical aspects. We also review the stimulus presentation possibilities (block, event-related) for visual or auditory paradigms and their advantage in both clinical and research setting. The second part mainly focus on various fMRI data post-processing tools such as Statistical Parametric Mapping (SPM) and Brain Voyager, and discuss the particulars of various preprocessing steps involved (realignment, co-registration, normalization, smoothing) in these software and also the statistical analysis principles of General Linear Modeling for final interpretation of a functional activation result.

Chronic aortic dissection is a complex disease with a heterogenous clinical course. Specialised imaging is necessary for the long-term surveillance of this disease to identify patients who meet the criteria for intervention, and to monitor surgically treated patients for complications. Whilst computed tomography and magnetic resonance imaging are the most widely utilised modalities, providing a high degree of anatomical detail and reproducible aortic measurements, they are not without significant limitations.

Background: Individuals with cocaine use disorder experience heightened motivation to pursue rewards tied to cocaine, often triggered by associated cues. Cue reactivity and subsequent craving significantly elevate the risk of substance use, creating a pressing need for treatments that can help alleviate cravings. However, no pharmaceutical therapies for treating cocaine use disorder have been approved.

Low-level auditory processing difficulties have been previously reported in children with Autism Spectrum Disorder (ASD), and some studies showed the relationship between these difficulties in the primary auditory cortex and language impairment in ASD. However, there is still a limited number of studies that comprehensively assess (i) amplitudes, latencies, and sensory gating effects in all early components of auditory processing (M50-M100-M200 complex) at the source level in magnetoencephalography with their relation to structural anatomy (gray matter volume, thickness, gyrification) (ii) and the association between brain metrics and clinical phenotype in the same group of children. To address this question, we used a standard paired-clicks paradigm in magnetoencephalography and brain morphometry analysis in children with and without ASD (NASD = 20, NTD = 20).

Meticulous clinical examination is essential for spinal disorders to utilize the diagnostic methods and technologies that strongly support physicians and enhance clinical practice. A significant change in the approach to diagnosing spinal disorders has occurred in the last three decades, which has enhanced a more nuanced understanding of spine pathology. Traditional radiographic methods such as conventional and functional X-rays and CT scans are still the first line in the diagnosis of spinal disorders due to their low cost and accessibility.

How anodal transcranial direct current stimulation (atDCS) and cathodal tDCS (ctDCS) affect brain networks is still unclear. Previous fMRI studies have yielded controversial results regarding the effects of atDCS and ctDCS on fMRI activation. The present study hypothesizes that the choice of fMRI paradigm may be a contributing factor to this divergence.
