  • A critical role of temporoparietal junction in the integration of top-down and bottom-up attentional control

    Qiong Wu, Chi-Fu Chang, Sisi Xi, I-Wen Huang, Zuxiang Liu, Chi-Hung Juan, Yanhong Wu, Jin Fan
    26 Aug 2015 | 8:38 am
    Abstract Information processing can be biased toward behaviorally relevant and salient stimuli by top-down (goal-directed) and bottom-up (stimulus-driven) attentional control processes respectively. However, the neural basis underlying the integration of these processes is not well understood. We employed functional magnetic resonance imaging (fMRI) and transcranial direct-current stimulation (tDCS) in humans to examine the brain mechanisms underlying the interaction between these two processes.

    Abstract Sleep-induced changes in human brain connectivity/excitability and their physiologic basis remain unclear, especially in the frontal lobe. We investigated sleep-induced connectivity and excitability changes in 11 patients who underwent chronic implantation of subdural electrodes for epilepsy surgery. Single-pulse electrical stimuli were directly injected to a part of the cortices, and cortico-cortical evoked potentials (CCEPs) and CCEP-related high-gamma activities (HGA: 100–200 Hz) were recorded from adjacent and remote cortices as proxies of effective connectivity and induced…
  • Epigenetic variation in the serotonin transporter gene predicts resting state functional connectivity strength within the salience-network

    Markus Muehlhan, Clemens Kirschbaum, Hans-Ulrich Wittchen, Nina Alexander
    24 Aug 2015 | 10:12 pm
    Abstract Genetic variation in the serotonin transporter gene (SLC6A4) has been associated with psychopathology and aberrant brain functioning in a plethora of clinical and imaging studies. In contrast, the neurobiological correlates of epigenetic signatures in SLC6A4, such as DNA methylation profiles, have only recently been explored in human brain imaging research. The present study is the first to apply a resting state functional magnetic resonance imaging approach to identify changes in brain networks related to SLC6A4 promoter methylation (N = 74 healthy individuals). The amygdalae…
  • Resting state functional MRI reveals abnormal network connectivity in neurofibromatosis 1

    Steffie N. Tomson, Matthew J. Schreiner, Manjari Narayan, Tena Rosser, Nicole Enrique, Alcino J. Silva, Genevera I. Allen, Susan Y. Bookheimer, Carrie E. Bearden
    24 Aug 2015 | 10:11 pm
    Abstract Neurofibromatosis type I (NF1) is a genetic disorder caused by mutations in the neurofibromin 1 gene at locus 17q11.2. Individuals with NF1 have an increased incidence of learning disabilities, attention deficits, and autism spectrum disorders. As a single-gene disorder, NF1 represents a valuable model for understanding gene–brain–behavior relationships. While mouse models have elucidated molecular and cellular mechanisms underlying learning deficits associated with this mutation, little is known about functional brain architecture in human subjects with NF1. To address this…

    Lara Schlaffke, Naima N. Rüther, Stefanie Heba, Lauren M. Haag, Thomas Schultz, Katharina Rosengarth, Martin Tegenthoff, Christian Bellebaum, Tobias Schmidt-Wilcke
    24 Aug 2015 | 10:11 pm
    Abstract Certain kinds of stimuli can be processed on multiple levels. While the neural correlates of different levels of processing (LOPs) have been investigated to some extent, most of the studies involve skills and/or knowledge already present when performing the task. In this study we specifically sought to identify neural correlates of an evolving skill that allows the transition from perceptual to a lexico-semantic stimulus analysis. Eighteen participants were trained to decode 12 letters of Morse code that were presented acoustically inside and outside of the scanner environment. Morse…

  • Fracture clinic day!

    27 Aug 2015 | 5:13 pm
    Fracture clinic day finally came! and I am so so glad that I didn’t get a cast. The doc said I got to start trying to move my arm, which I have been doing all day. It hurts but I need to get it moving so it doesn’t stiffen up. I have another appointment at the fracture clinic next week, where they are going to x-ray my hand again to check for a fracture, if there isn’t one but my hand still hurts then they will scan it and just go from there, but still got to keep it in the wrist splint until then. So fairly happy with the outcome of that appointment. I slept most of this…

    The production version of the Lada X-Ray has been caught on camera without any sort of camouflage.

  • Pineal Cyst: Incidentally detected on MRI for Sellar Tumour

    Sumer Sethi
    26 Aug 2015 | 12:53 am
    The pineal gland develops by the proliferation of walls of the third ventricle diverticulum in the diencephalic roof. A remnant of the pineal diverticulum or distension of its obliterated portion has been postulated as a possible source of pineal cyst. Non-neoplastic glial cysts of the pineal gland are relatively common findings on magnetic resonance imaging (MRI) studies of the brain, or in autopsy. This patient had an incidental pineal cyst on MRI done for pituitary adenoma. Famous Radiology Blog TeleRad Providers at Mail us at…

    Finally some common sense prevails: In a major relief to visiting radiologists at nursing homes and genetic centres, the Mumbai High court ruled that it is not the duty of a radiologist to maintain details in Form F. It is pure clerical work which is required to be done by the clinic, and the doctor can't be prosecuted for non-maintenance of details in the form, the court observed while quashing a criminal complaint against two radiologists.Famous Radiology Blog TeleRad Providers at Mail us at
