Ott ‘An Algorithm for the Empirical Determination of Intracranial Stereotactic Targets’, Stereotact Funct Neurosurg 1998;71: 29–35. In the Neurosurgical Department of Florence City Hospital we routinely employ basically the same method of calculation since 1996 for the surgical treatment of Parkinson...

OBJECTIVE To assess the accuracy of fetal sex determination at 11-14 weeks of gestation. METHODS Fetal gender assessment by ultrasound was prospectively carried out in 172 singleton pregnancies at 11-14 weeks of gestation immediately before chorionic villus sampling for karyotyping. The genital region was examined in a midsagittal plane and the fetal gender was assigned as male if the angle o...

Most pathologies (tumor, bleed, stroke) of the human brain can be determined by a symmetry-based analysis of neural scans showing the brain's 3D internal structure. Detecting departures of this internal structure from its normal bilateral symmetry can guide the classi cation of abnormalities. This process is facilitated by rst locating the ideal symmetry plane (midsagittal) with respect to whic...

This paper demonstrates the use of smoothing spline ANOVA and T tests to analyze whether the influence of syllable final consonants on the preceding vowel differs for articulation and acoustics. The onset of vowels either followed by phrase-final /r/ or by phrase-initial /r/ is compared for two Scottish English speakers. To measure articulatory differences of opposing vowel pairs, smoothing spl...

This article aims to understand the development of diachronic asymmetries in phonological systems by evaluating variability stability synchronic contrasts. We focus on sonorant involving secondary palatalisation, grounded claim that palatalised laterals are more common than rhotics cross-linguistically. Our analysis reports acoustic and articulatory data Scottish Gaelic, a Celtic language with ...

The software allows displaying the positions of the sensors that are simultaneously played with the spe...

Magnetic resonance imaging was used to produce midsagittal images of the corpus callosum of 19 right-handed adult male and female subjects. The preliminary findings of this study indicate that significant adaptation in the anterior midbody of the corpus callosum has occurred to accommodate multiple language capacity in bilingual individuals compared to monolingual individuals. The main interpre...

An investigation of the identifiable real-time sonographic features of the normal infant brain in the horizontal, coronal, inclined coronal, and midsagittal planes was undertaken. Correlations were made of sonograms of intact brains in vitro, corresponding brain sections, and sonograms in vivo. A large number of anatomic structures could be consistently depicted including cisterns, fissures, fa...

This study uses real-time MRI to investigate shaping aspects of two English sibilant fricatives. The purpose of this article is to 1) develop linguistically meaningful quantitative measurements based on vocal tract features that robustly capture the shaping aspects of the two fricatives, and 2) provide qualitative analyses of fricative shaping. Data was recorded in both midsagittal and coronal ...

Background: Intrapartum ultrasound (ITU) techniques have been described only in maternal semi-recumbent position. However, other birthing positions, such as side-lying, are more comfortable for many mothers. The present study aimed to test the hypothesis that ITU measurements can be obtained lateral positions during second stage of labor. Methods: A single-center, prospective observational was ...
