Recent physiological studies have implicated theta - a high-amplitude 4-8 Hz oscillation that is prominent in rat hippocampus during locomotion, orienting and other voluntary behaviors - in synaptic plasticity, information coding and the function of working memory. Intracranial recordings from human cortex have revealed evidence of high-amplitude theta

A study on ratio of the Θ–Theta functions
Applied Mathematics and Computation, 2004The authors show that the four fundamental theta functions satisfy a nonlinear differential equation, involving also the quotient of the first and third theta functions. They use some results from the monograph of \textit{D. Mumford} [Tata lectures on theta.

Theta series on the theta group
Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 1988This paper is a continuation of a similar study for the Hecke groups \(G(\sqrt{2})\) and \(G(\sqrt{3})\) [Math. Z. 197, 69--96 (1988; Zbl 0632.10024)]. It contains a complete description of all modular forms f on subgroups of the theta group \(\Gamma_{\tau}\) which satisfy: (1) \(f\) is a sum of modular forms of integral weight and different multiplier

Theta theory explores the lexicon as an interface in the strict sense, as facilitating the flow of informaiton between cognition and the computational system of language. It argues for the traditional concept of a listed lexicon, where semantic roles are encoded as features of verbs, and against event decomposition.

On \(\theta\)-connectedness and \(\theta\)-closure spaces
2002If \((X,{\mathcal T})\) is a topological space and \(A\subseteq X\), then the \(\theta\)-closure of \(A\), denoted by cl\(_\theta(A)\) is the set \(\{x:\) each closed neighbourhood of \(x\) meets \(A\}\). A set \(C\) is \(\theta\)-closed if \(C=\text{ cl}_\theta(C)\); the \(\theta\)-closed sets form the closed sets of a topology called the \(\theta ...

Summary: We define the \(\theta\)-tightness and \(\theta\)-bitightness of a topological space and give some results in connection with these notions. In particular we prove that for every subset \(A\) of an Urysohn space \(X\) it holds \(| [A]_ \theta | \leq | A|^{\text{bt}_ \theta (X)}\), where \([A]_ \theta\) denotes the smallest \(\theta\)-closed ...

Premature temporal theta (PT theta).
Electroencephalography and clinical neurophysiology, 1987A distinctive pattern called premature temporal theta (PT theta) was studied in 436 infants, ranging in age from 24 to 46 weeks. The pattern is seen in early prematurity, maximizes at 29-31 weeks and then diminishes and disappears near term. Usually the pattern is found independently on both temporal areas, but with a right-sided preference.
