Publication date: Available online 6 January 2016 *Source:*Brain Research Bulletin Author(s): Carla García-Barba, Laura Medina-Ceja Fast ripples (FR, 250–600Hz) are field potentials that occur only in those areas capable of generating seizures, such as the hippocampus, and modulation of FR by serotonin has been reported. Therefore, we hypothesized that the receptor antagonists 5HT1A and 5HT2A, B, C will increase FR in rats treated with kainic acid (KA, 0.8μg/0.5μl). For this purpose, the intracranial EEG recordings of the hippocampus from animals treated with KA and the serotonin an...περισσότερα »

Decisions about the past are guided by reinstatement of specific memories in the hippocampus and perirhinal cortex

Alexandros G. SfakianakisστοΝευρολογία κ' ΝευροχειρουργικήΠριν από 5 δευτερόλεπτα
Publication date: 15 February 2016 *Source:*NeuroImage, Volume 127 Author(s): Michael L. Mack, Alison R. Preston When faced with a new challenge, we often reflect on related past experiences to guide our behavior. The ability to retrieve memories that overlap with current experience, a process known as pattern completion, is theorized as a critical function of the hippocampus. Although this view has influenced research for decades, there is little empirical support for hippocampal pattern completion to individual memory elements and its influence on behavior. We used pattern analysi... περισσότερα »

Thinking about thinking: Neural mechanisms and effects on memory

Alexandros G. SfakianakisστοΝευρολογία κ' ΝευροχειρουργικήΠριν από 5 δευτερόλεπτα
[image: S10538119.gif] Publication date: 15 February 2016 *Source:*NeuroImage, Volume 127 Author(s): Corinna Bonhage, Friederike Weber, Cornelia Exner, Philipp Kanske It is a well-established finding that memory encoding is impaired if an external secondary task (e.g. tone discrimination) is performed simultaneously. Yet, while studying we are also often engaged in internal secondary tasks such as planning, ruminating, or daydreaming. It remains unclear whether such a secondary internal task has similar effects on memory and what the neural mechanisms underlying such an influence are...περισσότερα »

Impulse source localization in an urban environment: Time reversal versus time matching

Αλέξανδρος ΣφακιανάκηςστοAudiology by Alexandros G. SfakianakisΠριν από 6 δευτερόλεπτα
This study investigates two approaches for localizing an impulse sound source with distributed sensors in an urban environment under controlled processing time. In both approaches, the numerical model used for calculating the sound propagation is a finite-difference time-domain(FDTD) model. The simulations are drastically accelerated by restricting to the lower frequencies of the impulse signals and are evaluated against in situ measurements. The first tested localization technique relies on the time reversal of the measurements with the model. In the second technique, the source i...περισσότερα »

Sub-harmonic broadband humps and tip noise in low-speed ring fans

Αλέξανδρος ΣφακιανάκηςστοAudiology by Alexandros G. SfakianakisΠριν από 6 δευτερόλεπτα
A joint experimental and numerical study has been achieved on a low-speed axial ring fan in clean inflow. Experimental evidence shows large periodic broadband humps at lower frequencies than the blade passing frequencies and harmonics even at design conditions. These sub-harmonic humps are also found to be sensitive to the fan process and consequently to its tip geometry. Softer fans yield more intense humps more shifted to lower frequencies with respect to the fan harmonics. Unsteady turbulent flow simulations of this ring fan mounted on a test plenum have been achieved by four d... περισσότερα »

In-plane and out-of-plane motions of the human tympanic membrane

Αλέξανδρος ΣφακιανάκηςστοAudiology by Alexandros G. SfakianakisΠριν από 6 δευτερόλεπτα
Computer-controlled digital holographic techniques are developed and used to measure shape and four-dimensional nano-scale displacements of the surface of the tympanic membrane (TM) in cadaveric human ears in response to tonal sounds. The combination of these measurements (shape and sound-induced motions) allows the calculation of the out-of-plane (perpendicular to the surface) and in-plane (tangential) motion components at over 1 000 000 points on the TM surface with a high-degree of accuracy and sensitivity. A general conclusion is that the in-plane motion components are 10–20 d...περισσότερα »

Acoustic impedance of micro perforated membranes: Velocity continuity condition at the perforation boundary

Αλέξανδρος ΣφακιανάκηςστοAudiology by Alexandros G. SfakianakisΠριν από 6 δευτερόλεπτα
The classic analytical model for the sound absorption of micro perforated materials is well developed and is based on a boundary condition where the velocity of the material is assumed to be zero, which is accurate when the material vibration is negligible. This paper develops an analytical model for finite-sized circular micro perforated membranes (MPMs) by applying a boundary condition such that the velocity of air particles on the hole wall boundary is equal to the membrane vibrationvelocity (a zero-slip condition). The acoustic impedance of the perforation, which varies with it... περισσότερα »

*Quiet transcranial magnetic stimulation: Status and future directions.* Conf Proc IEEE Eng Med Biol Soc. 2015 Aug;2015:226-229 Authors: Peterchev AV, Murphy DL, Goetz SM Abstract A significant limitation of transcranial magnetic stimulation (TMS) is that the magnetic pulse delivery is associated with a loud clicking sound as high as 140 dB resulting from electromagnetic forces. The loud noise significantly impedes both basic research and clinical applications of TMS. It effectively makes TMS less focal since every click activates auditory cortex, brainstem, and other connected r...περισσότερα »

Alexandros G. SfakianakisστοΝοσολογίαΠριν από 33 δευτερόλεπτα
Turkey's electricity mix is dominated by fossil fuels, but the country has ambitious future targets for renewable and nuclear energy. At present, environmental impacts of electricity generation in Turkey are unknown so this paper represents a first attempt to fill this knowledge gap. Taking a life cycle approach, the study considers eleven impacts from electricity generation over the period 1990–2014. All 516 power plants currently operational in Turkey are assessed: lignite, hard coal, natural gas, hydro, onshore wind and geothermal. The results show that the annual impacts from ... περισσότερα »

Abstract HEV, as a zoonotic disease virus, was seldom studied in dogs especially in stray dogs. As previously reported, dog might be an accidental host of HEV for human beings and some risk factors might play an important role in HEV transmission. Thus, we designed this study to evaluate the seroprevalence of HEV infection among dogs in several cities in Guangdong province of China. This surveillance may help us understand risk factors including location, gender, live type and diet habit for HEV transmission. The overall seroprevalence of anti-HEV antibodies in dogs was 19.00%.

Somatic arousal and sleepiness/fatigue among patients with sleep-disordered breathing

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 1 ώρα
Abstract Objectives In a large clinical sample, we tested the hypothesis that levels of sleepiness and fatigue among upper airway resistance syndrome (UARS) patients are correlated with levels of somatic arousal (SA; reflecting the sympathetic nervous system component of the stress response). We also tested the correlations of post-treatment change in these three parameters, and we extended the investigation to obstructive sleep apnea/hypopnea (OSA/H) patients. Methods From 5 years of patient data, we obtained scores on the body sensation questionnaire (BSQ), measuring the level ... περισσότερα »

Clinical diagnostics and therapy monitoring in the congenital disorders of glycosylation

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 1 ώρα
Abstract Abnormal protein glycosylation is observed in many common disorders like cancer, inflammation, Alzheimer's disease and diabetes. However, the actual use of this information in clinical diagnostics is still very limited. Information is usually derived from analysis of total serum N-glycan profiling methods, whereas the current use of glycoprotein biomarkers in the clinical setting is commonly based on protein levels. It can be envisioned that combining protein levels and their glycan isoforms would increase specificity for early diagnosis and therapy monitoring. To establi... περισσότερα »
