Previously, we demonstrated that initial acquisition of a lever-press task resulted in higher levels of activity-regulated cytoskeleton-associated protein (Arc) mRNA induction than did overtrained performance (Kelly and Deadwyler, 2002). The present study extends this finding by characterizing (1) the behavioral regulation of Arc protein expression, (2) the time course of decay of Arc mRNA sign...

Insight into the processing dynamics and other neurophysiological properties of different hippocampal subfields is critically important for understanding hippocampal function. In this study, we compared shifts in the center of mass (COM) of CA3 and CA1 place fields in a familiar and completely novel environment. Place fields in CA1 and CA3 were simultaneously recorded as rats ran along a closed...

source localization is an essential part of array signal processing including radar, sonar, seismology and oceanography applications. the performance of the presented source localization methods are degraded substantially in practical situations. one of the conditions which decreases the performance o

Understanding how the hippocampus processes information critical for establishing spatial and declarative memories will benefit greatly from determining not only what kind of information the hippocampus registers, but also how this information is processed across the different hippocampal subfields. We addressed this question using a novel immediate-early gene-based brain-imaging method (Arc/H1...

entrepreneurship as any emergence scientific field is confronting with scientific legitimacy. entrepreneurship as a scientific field has received increasing attention but doesn't acceptance as well as. from this point of view entrepreneurship is confronting with legitimacy challenge. in this article entrepreneurship as a emergence scientific field that is based on the five dimension consis...

‎we obtain the porc formulae for the number of non-associative algebras‎ ‎of dimension 2‎, ‎3 and 4 over the finite field gf$(q)$‎. ‎we also give some‎ ‎asymptotic bounds for the number of algebras of dimension $n$ over gf$(q)$.
