The extra spike appears to arise from a large depolarizing afterpotential crossing the falling threshold several milliseconds following a spike; extra spikes themselves may generate further extra spikes in a similar manner, generating burst patterns which are strikingly similar to those of epileptic neurons.William H.

One of these studies is described here and an attempt is made to generalize from all eighteen about the relationship between size of incentives and reduction in nonresponse. These generalizations should be of value for the design of mail survey studies.J.

Two highly inbred strains (BALB/cBy and C57BL/6By), their F1 hybrids, a backcross generation, and seven recombinant-inbred strains derived from the F2 generation were tested. It was concluded that there is a genetic component to the response of female mice to placenta in the absence of previous experience, and that more than one, but possibly as few as two loci are involved. Alternative explanations of average dominance for placentophagia and for no placentophagia (by the promotion of competing responses) were considered.Dr. Mark B. Kristalkristal@buffalo.eduBasil E.
