Adult mammalian brains are capable of some structural plasticity. Although the basic cellular mechanisms underlying learning and memory are being revealed, extrinsic factors contributing to this plasticity remain unspecified. White-footed mice (Peromyscus leucopus) are particularly well suited to investigate brain plasticity because they show marked(More)

We determine the linear complexity of a family of p 2-periodic binary threshold sequences derived from Fermat quotients modulo an odd prime p, where p satisfies 2 p−1 ≡ 1 (mod p 2). The linear complexity equals p 2 − p or p 2 − 1, depending whether p ≡ 1 or 3 (mod 4). Our research extends the results from previous work on the linear complexity of the(More)
Previous studies have localized a central pattern generator for mastication to the midline pontomedullary reticular formation (RF) based on cortically induced ororhythmic movements. The present study determined whether this same substrate mediated licking responses evoked by more natural stimuli. Licking in the awake rat was initiated either through an(More)
We determine the linear complexity of p 2-periodic binary threshold sequences derived from polynomial quotient, which is defined by the function (u w −u wp)/p (mod p). When w = (p−1)/2 and 2 p−1 ≡ 1 (mod p 2), we show that the linear complexity is equal to one of the following values p 2 − 1, p 2 − p, (p 2 + p)/2 + 1, (p 2 − p)/2 , depending whether p ≡ 1,(More)
We describe the trace representations of two families of binary sequences derived from the Fermat quotients modulo an odd prime p (one is the binary threshold sequences and the other is the Legendre Fermat quotient sequences) by determining the defining pairs of all binary characteristic sequences of cosets, which coincide with the sets of pre-images modulo(More)
