    The right temporoparietal junction supports speech tracking during selective listening: Evidence from concurrent EEG-fMRI.
    J Neurosci 2017 Oct 23. Epub 2017 Oct 23.
    Biological Psychology Lab, Department of Psychology, European Medical School, Carl von Ossietzky Universität, 26111 Oldenburg, Germany.
    Listening selectively to one out of several competing speakers in a "cocktail party" situation is a highly demanding task. It relies on a widespread cortical network, including auditory sensory but also frontal and parietal brain regions involved in controlling auditory attention. Previous work has shown that, during selective listening, ongoing neural activity in auditory sensory areas is dominated by the attended speech stream, whereas competing input is suppressed.

    EEG source estimation accuracy in presence of simulated cortical lesions.
    Conf Proc IEEE Eng Med Biol Soc 2017 Jul;2017:544-547
    Methods to reconstruct the neuroelectrical activity in the brain source space can be used to improve the spatial resolution of scalp-recorded EEG and to estimate the locations of electrical sources in the brain. This procedure can improve the investigation of the functional organization of the human brain, exploiting the high temporal resolution of EEG to follow the temporal dynamics of information processing. As for today, the uncertainties about the effects of inhomogeneities due to brain lesions preclude the adoption of EEG functional mapping on patients with lesioned brain. Read More

    Immediate Near-Total Scalp Reconstruction with Artificial Dermis on Exposed Calvarium.
    Arch Craniofac Surg 2016 Dec 23;17(4):233-236. Epub 2016 Dec 23.
    Department of Plastic and Reconstructive Surgery, St. Vincent's Hospital, College of Medicine, The Catholic University of Korea, Suwon, Korea.
    Scalp defect management is complicated secondary to reduced laxity in the scalp and forehead area. For reconstruction of larger defects with exposed bone and loss of the periosteal layer, free flap reconstruction is one option for single-stage surgery, although the procedure is lengthy and includes the possibility of flap loss. We successfully performed a single-stage reconstruction of a large scalp defect using a combination of artificial dermis, split-thickness skin graft, and full-thickness skin graft following wide excision of a cutaneous angiosarcoma, and present our method as one option for the treatment of large oncologic surgical defects in patients who are poor candidates for free flap surgery.

It is currently unclear how this generalizes to more complex sound environments. Read More

    Comparing diffuse optical tomography and functional magnetic resonance imaging signals during a cognitive task: pilot study.
    Neurophotonics 2017 Jan 15;4(1):015003. Epub 2017 Mar 15.
    Universidad de La Laguna , Faculty of Health Sciences (Medicine Section), Department of Basic Medical Science (Physiology Section), Spain.
    Diffuse optical tomography (DOT) measures concentration changes in both oxy- and deoxyhemoglobin providing three-dimensional images of local brain activations. A pilot study, which compares both DOT and functional magnetic resonance imaging (fMRI) volumes through t-maps given by canonical statistical parametric mapping (SPM) processing for both data modalities, is presented. The DOT series were processed using a method that is based on a Bayesian filter application on raw DOT data to remove physiological changes and minimum description length application index to select a number of singular values, which reduce the data dimensionality during image reconstruction and adaptation of DOT volume series to normalized standard space.

    Aesthetic Eyebrow Reconstruction with an Expanded Scalp Island Flap Pedicled by the Superficial Temporal Artery.
    Aesthetic Plast Surg 2017 Jun 9;41(3):563-567. Epub 2017 Mar 9.
    Department of Plastic Surgery, The Third Hospital of Wuhan, Wuhan, Hubei, China.
    Purpose: This case study demonstrates a new operative method of eyebrow reconstruction, in which the hair density of the reconstructed eyebrow is controlled by the surgeon and is more similar to that of the uninjured side, resulting in a more natural facial expression and greater aesthetic value for our patients.

    Materials And Methods: The operation was divided into two stages: Stage 1: Implantation of a soft tissue expander into the corresponding subgaleal position of the parietal branch of the superficial temporal artery on the injured side, followed by dilation of the expander until the density of the hair on the expanded scalp reached a suitable value and was lower than that of the uninjured eyebrow. Stage 2: Harvesting of the scalp island flap pedicled by the superficial temporal artery, the end of which was attached to the expanded scalp, followed by the downward movement of the flap to the defect site of the eyebrow via a subcutaneous tunnel, resulting in new eyebrow formation.

    Graph fractional-order total variation EEG source reconstruction.
    Conf Proc IEEE Eng Med Biol Soc 2016 08;2016:101-104
    EEG source imaging is able to reconstruct sources in the brain from scalp measurements with high temporal resolution. Due to the limited number of sensors, it is very challenging to locate the source accurately with high spatial resolution. Recently, several total variation (TV) based methods have been proposed to explore sparsity of the source spatial gradients, which is based on the assumption that the source is constant at each subregion.
