Serial coronal or sagittal sections were stained for myelin and examined in 6 inbred, 4 hybrid, and 2 outbred mouse strains. Absent corpus callosum was seen only in BALB/cJ as reported by Wimer, but a wide range of the size of corpus callosum was also noted. The action of a major gene was not evident in backcross or F2 generations; polygenic and perhaps epistatic inheritance was indicated. In A...

Objective: To record somatosensory evoked potentials (SEPs) to median nerve stimulation by chronically implanted electrodes in the parieto-rolandic opercular area of 9 epileptic patients, in order to evaluate whether somatosensory evoked responses could be generated in the second somatosensory area (SII) earlier than 40 ms after stimulus. Methods: Nine patients (4 males, 5 females) with drug-re...

We report a morphological and biochemical analysis on the presence, distribution and quantification of vasotocin in the hypothalamus and limbic region of the budgerigar Melopsittacus undulatus, using immunohistochemistry on serial sections and competitive enzyme linked immunoadsorbent assay measurements on tissue extracts. Analysis of the sections showed large vasotocin-immunoreactive neurons i...

BACKGROUND Neurite orientation dispersion and density imaging (NODDI) is a diffusion magnetic resonance imaging (MRI) technique with the potential to visualize the microstructure of the brain. Revolutionary histological methods to render the mouse brain transparent have recently been developed, but verification of NODDI by these methods has not been reported. PURPOSE To confirm the concordanc...

The subfornical organ (SFO) and the periventricular tissue of the anteroventral third ventricle (AV3V) have been shown to be important for the central action of circulating angiotensin. Recent anatomical findings have elucidated neural connections between the SFO and several structures within the AV3V region. The present study examined the function of fibers between the SFO and the median preop...

Male and female mice from HI and LO lines selectively bred by Collins for strength of lateralization were tested for paw preference and then studied histologically to assess size of forebrain commissures and myelination of the corpus callosum. When compared to LO line mice, HI line mice were more strongly lateralized for paw preference and had larger brains as well as greater cross-sectional ar...

BACKGROUND AND PURPOSE Tumor volume and cartilage invasion have been suggested as prognostic factors of glottic carcinomas following definitive radiation therapy. Radiologic examinations provide additional information regarding the deep extension of tumor. We determined whether dynamic helical CT can predict local control of early (T1 and T2 stage) glottic carcinomas treated with definitive rad...

PURPOSE OF REVIEW To give an overview of the evolvement of transoral laser microsurgery (TLM) in the treatment of early glottic carcinoma and highlight the contribution of recent literature. RECENT FINDINGS The indications and limits of TLM have been well specified. Effects on swallowing have been well documented. Introduction of narrow-band imaging (NBI) and diffusion-weighted magnetic reson...

Several therapeutic options are used for treatment of early stage glottic carcinoma (Tis/T1/T2): open partial laryngectomy (OPL), radiotherapy and CO2 laser-assisted endoscopic surgery. Laser surgery has gradually gained approval in the management of laryngeal cancer. We present our experience in endoscopic laser surgery for early stage glottic carcinomas. This was a retrospective analysis of 7...

An experimental investigation has been made of the site and mode of termination of the 3 groups of afferent fibres to the olfactory bulb which come from more caudal parts of the cerebral hemisphere. Lesions have been placed in the relevant parts of the brain of the rat and the resulting degeneration of axon terminals in the olfactory bulb studied with the electron microscope. All 3 groups of th...
