...Ofer Tchernichovski; Olga Feher; Daniel Fimiarz; Dalton Conley; Joel D. Levine; Daniel J. C. Kronauer; Michael H. Dickinson ABSTRACT Distributed social learning may occur at many temporal and spatial scales, but it rarely adds up to a stable culture. Cultures vary in stability and diversity...

... were left attached to the isolated CNS. At raised temperatures of 28°C compared to 23°C both spontaneous and evoked electrical activity were reversibly reduced. Together these results show that the isolated CNS of the newborn opossum survives well in culture. The preparation offers advantages...

...L. Vyklicky; J. Nicholls ABSTRACT Individual medial and lateral nociceptive (N) cells of the leech have been paired with a variety of different target cells to determine the patterns and the properties of the connections made in culture. Lateral nociceptive N cells did not make electrical...

... identified neurones in culture. An important requirement for sprouting of leech neurones is the substrate. Neurites grow only slowly and sparsely on polylysine or vertebrate laminin. The extracellular matrix of leech ganglion capsules contains a protease-sensitive factor which can be extracted with urea...

...H. Arechiga; M. Chiquet; D. P. Kuffler; J. G. Nicholls ABSTRACT Connections made in culture by identified leech neurones have been studied using pairs of cells that contain various transmitters. These cells were: motoneurones innervating the heart; the anterior pagoda neurones (which contain both...
