ABSTRACT

The detailed study of arm ossicles, particularly the lateral arm plates, is providing valuable information in the elucidation of ophiuroid taxonomy. The present study describes in detail 16 species of brittle stars from Araçá Bay, Brazil. This information is used to construct the first interactive electronic key, providing a valuable resource for a broad range of researchers. Brittle stars families were divided into three groups based on their spatial distribution: i) infaunal species of intertidal and shallow subtidal belonging to Amphiuridae and Ophiactidae, ii) epizoic species belonging to Amphiuridae, Ophiactidae, and Ophiotrichidae and, iii) epifaunal species of the subtidal belonging to Ophiodermatidae and Hemieuryalidae. In the global context of recent revisions of ophiuroid taxonomy, the present work provides additional characters for use in future phylogenetic studies.

ABSTRACT

The usual drug used in the Wada test is amobarbital, but it is not available in Brazil. Propofol was already used by Bazin et al. in 1998, and in their report the test resulted good in the absence of any adverse effect. We report the use of propofol as the anesthetic for the Wada test. The test was carried out in a 26 years old woman with temporal medial lobe epilepsy refractory to medical treatment. Language functions and memory were tested after injection in both hemispheres by three procedures (Seattle, Montreal and Interview procedures). Propofol showed to be good to carry on the Wada test.
