rheoscopicadj.

Brit.

/ˌriːəˈskɒpɪk/, U.S.

/ˌriəˈskɑpɪk/

Forms: 1800s reoscopic, 1800s– rheoscopic.

Origin: Formed within English, by compounding. Etymons: rheo- comb. form, -scopic comb. form, rheoscope n.

Etymology: < rheo- comb. form + -scopic comb. form. Compare earlier rheoscope n. In sense 1 after French rhéoscopique (1842 or earlier); in rheoscopic frog after French grenouille rhéoscopique (E. du Bois-Raymond 1850, in Ann. de chim. et de physique 30 184).

1. Designating a preparation of a muscle and attached nerve of a frog used for detecting electric currents; of or relating to such a preparation; esp. in rheoscopic frog. Cf. physiological rheoscope n. at physiological adj. Compounds. Now historical.

1983 Med. Instrumentation 17 235 The rheoscopic frog, an isolated nerve-muscle preparation from the leg of a frog,..was used for more than half of the 19th century as a biological galvanometer.

2. Capable of detecting an electric current (as opposed to measuring it); relating to such detection. Now rare.
