The studies of nudibranch embryonic development has been limited to the temperate zone and include Rostanga pulchra (Chia & Koss 1978), Doridella steinbrege (Bickell & Chia 1979), Hermissenda
crassicornis (Avila et al.
Larval rearing, metamorphosis, growth and reproduction of the eolid nudibranch Hermissenda
crassicorni (Eschscholtz, 1831) (Gastropoda: Opisthobranchia).
Average tidal heights changed for only four species (the sea slug Hermissenda
crassicornis, the mussel Mytilus californianus, the crab Pachygrapsus crassipes, and the limpet Tectura scutum).
But if the light appears repeatedly just before and during shaking, this snail, called Hermissenda
crassicornis, eventually learns to contract its foot when light flashes, "just as Pavlov's dog would salivate when the bell occurred, as if the smell of meat were there," Alkon says.
PKC activation by low concentrations of bryostatins has been shown to enhance long-term memory in the nudibranch Hermissenda
(Alkon et al.
contribute a paper on the enhancement of memory in Hermissenda
by the protein kinase C (PKC) agonist bryostatin.
Many aspects of memory and recall can be studied especially well in the nudibranch Hermissenda
because the temporal specificity of experimental effects can be determined within 2 or 3 min, and the process of long-term memory consolidation occurs within 220 to 230 min after conditioning (Epstein et al.
The nudibranch mollusc Hermissenda
crassicornis, the subject of this review, is one preparation that has contributed to an understanding of Pavlovian conditioning at the cellular, molecular, and systems level.
Examples of their use include Aplysia californica as a model of sensitization of the gill-withdrawal reflex (Kandel, 1976), Hermissenda
crassicornis as a model of classical conditioning (Alkon, 1987), and Lymnaea stagnalis as a model of classical conditioning and operant conditioning (Lukowiak et al.
