This study proposes that plasticity of dendritic spine formation may be modeled as distribution patterns imbedded in a spine length-dependent and density-dependent stochastic process. Modeling the jewel fish tectal interneuron revealed a critical 10-36 micron region where spine length plasticity was predicted to be most detectable. This hypothesis was(More)
Seyfried, Glasser, and Yu recently reported that the DBA/2J mouse genotype, which is innately susceptible to audiogenic seizures, has high neonatal levels of thyroxine (T4) and that neonatal injections of T4 induce susceptibility in the C57BL/6J mouse. In the C57BL/6J mouse, neonatal T4 injections produced a temporary peripheral auditory dysfunction which(More)
The crystal structure of the title copper(II) complex, [Cu(C(18)H(36)N(8)O(4))]SO(4).4.5H(2)O, formed with the tetraamide cyclam derivative 2-(4,8,11-triscarbamoylmethyl-1,4,8,11-tetraazacyclotetradec-1-yl)acetamide (TETAM), is described. The macrocycle lies on an inversion centre occupied by the hexacoordinated Cu atom. The four macrocyclic tertiary amines(More)
We discuss two techniques involving density functional theory (i.e., ab initio molecular dynamics simulations and frozen density functional theory) which show promise for applications directed towards understanding reactions in complex media. Preliminary results for the simulation of the conformational dynamics of an isolated analogue of alanine dipeptide(More)
Patterned electrical stimulation of the superior olivary complex (SOC) which simulated the neural frequency following response (FFR) extracellular potential was used as a stimulus in behavioral frequency discrimination and cortical evoked potential studies. Behavioral judgments of SOC stimulation frequency were found to be as accurate as those obtained for(More)
