We tested whether the recovered ability of rats to discriminate NaCl from KCl after chorda tympani nerve transection (CTX) is causally linked to nerve regeneration or some other compensatory process. Rats were presurgically trained in an operant NaCl vs. KCl discrimination task. Rats with regenerated nerves, histologically confirmed by anterior tongue taste pore counts and tested 62 days after ...

Complete sequencing of pJIE137 revealed a backbone closely related to p271A, encoding a novel RepA protein but with a similar organization and up to ∼70% nucleotide identity to IncN plasmids. A region in pJIE137 resembling the IncN CUP regulon is mostly missing from p271A, presumably due to recombination. The class 1 In/Tn and ISEcp1-bla(CTX-M-62) transposition unit in pJIE137 and a putative tr...

Calcium/calmodulin-dependent kinases (CaM-kinases) are central to various forms of long-term memory (LTM) in a number of evolutionarily diverse organisms. However, it is still largely unknown what contributions specific CaM-kinases make to different phases of the same specific type of memory, such as acquisition, or early, intermediate, and late consolidation of associative LTM after classical ...
