Brain areas in the frontal lobe have been implicated in behavioral flexibility and control. The study by Johnston et al. in this issue of Neuron provides novel insights into the roles of the prefrontal and anterior cingulate cortices in controlling behavior.

(D) Viruses Since Lindner (1910) first described elementary bodies in a urethral discharge, various attempts have been made to prove a viral aetiology by various workers including Halberstaedter and von Prowazek (1910); Thygeson and Mengert (1936); Harkness (1945); Johnston and McEwin (1945); Williams (1946); Dunlop, Jones, and Al-Hussaini (1964); Dunlop, Harper, Al-Hussaini, Garland, Treharne,...

There is recent concern over the status of many Neotropical migrant bird populations. Reports of declining numbers and the continuing loss and degradation of breeding and overwintering habitats have prompted an upsurge of interest in the conservation biology of these birds (review papers in Hagan and Johnston 1992). Fragmentation of the breeding habitat in North America often is cited as one of...

This paper will explain the asymmetry parallelism between node ‘because’ and toki ‘when’ in terms of the availability of Evidential Phrase in syntax, following the analysis by Chinque [1], Speas [2] and Tenny [3]. This (in)compatibility of Evidential Phrases with Adjunct Clauses is further motivated by the syntax-semantics difference of Adjunct Clauses discussed by Johnston [4].
