Abundance and species richness of Coreoidea (Hemiptera: Heteroptera) from Parque Estadual do Turvo, Southern Brazil.

The coreoid fauna from Neotropics is poorly known, especially in terms of community studies. Aiming at contributing to this knowledge, a two-year study was carried out at Parque Estadual do Turvo, Municipality of Derrubadas, state of Rio Grande do Sul, Brazil, to evaluate the composition, abundance and species richness of Coreoidea. Samplings were conducted in the springs of 2003 and 2004 (October), and autumns of 2004 and 2005 (May), using beating tray method, along two trails of the park.

Brazilian Portuguese Language version of the "Tinnitus Handicap Inventory": validity and reproducibility.

Unlabelled: Tinnitus can greatly impact an individual's life quality and it is very difficult to quantify.

Aim: To determine the reproducibility and validity of a Brazilian Portuguese version of the Tinnitus Handicap Inventory (THI), a self-applicable questionnaire which assesses tinnitus impact on patient's life quality.

Materials And Methods: This was a prospective transversal study.

Functional variability of the human cortical motor map: electrical stimulation findings in perirolandic epilepsy surgery.

The purpose of this study was to assess the cortical representation of sensorimotor functions in patients undergoing perirolandic epilepsy surgery, focusing on somatotopy, mosaicism, and variability of function in relation to the classic motor homunculus. The authors studied 36 patients in whom intraoperative or extraoperative electrical cortical stimulation to map motor functions was performed. A computer program was devised to register electrode number, stimulation parameters, and response to each stimulus.
