| activity and habituation in the brain of the polyclad flatworm freemania litoricola. | 1. a variety of spontaneously active units was measured in the brain of the polyclad flatworm freemania litoricola. following application of mgcl2 there was both a decrease in number of active units and a decrease in frequency of firing of those cells which persisted in their activity. 2. receptors which respond to vibration stimuli evoke potentials in the posterior part of the brain. repetitive stimulation leads to habituation, the extent of which is dependent on both the number of times stimul ... | 1975 | 1206341 |
| electrophysiology of the peripheral nerve net in the polyclad flatworm freemania litoricola. | 1. a diffuse-conducting system close to the dorsal epithelium of the polyclad flatworm freemania litoricola is described. tactile stimuli elicit small action potentials which can be conducted around lesions through the body wall. the potentials can occur in bursts or barrages. 2. this conducting system appears to be insensitive to mg2+ ions. 3. conduction velocities (0-26--71 m/sec) vary over the animal. conduction spread in the anterior half of the animal appears to be greater than that in the ... | 1975 | 1206342 |
| litoricolaceae fam. nov., to include litoricola lipolytica gen. nov., sp. nov., a marine bacterium belonging to the order oceanospirillales. | a gram-negative, non-motile, chemoheterotrophic, facultatively aerobic, short-rod-shaped bacterium, designated imcc1097(t), was isolated from coastal seawater (10 m depth) of the east sea, korea. the temperature, ph and nacl ranges for growth were 15-30 degrees c, ph 5.0-10.0 and 1.5-10 % nacl. the colonies of the strain were very small, having a mean diameter of 0.05 mm. 16s rrna gene sequence data indicated that the strain was most closely related to genera within the class gammaproteobacteria ... | 2007 | 17684259 |
| litoricola marina sp. nov. | a gram-negative, non-pigmented, non-motile, chemoheterotrophic marine bacterium, designated strain imcc2782(t), was isolated from a surface seawater sample of the yellow sea, korea. on the basis of 16s rrna gene sequence analysis and phenotypic and genotypic characterization, strain imcc2782(t) is shown to represent a novel species of the genus litoricola. strain imcc2782(t) grew at 15-37 degrees c and tolerated 7.5% nacl. based on 16s rrna gene sequences, strain imcc2782(t) was related most clo ... | 2010 | 19667367 |
