  The Theta Rhythm..... . . . . .
The behavioral correlates of theta in humans are not as simple as in the cat or the rat, however it is theorized that the same basic mechanism is being utilized across all species exhibiting theta.
It is theorized that theta activity in the posterior areas of the brain is involved with selective attention, and in the frontal areas with the cognitive filtering, ìdisattending to extraneous stimuliî, neccesary for entry into the hypnotic state (Crawford, 1994).
Theta rhythms have been observed in humans and animals during a wide variety of activities; thus understanding the role of theta is integral to the understanding of the functioning brain.

 THETA Uganda   (Site not responding. Last check: 2007-10-12)
THETA has taken a lead role in a collaborative effort to set standards for traditional medicine for a group of nine African countries.
The focus of the THETA method is to improve the health of rural Ugandan populations by involving healers through training in health education, provision of quality care and counselling, and initiating community support initiatives for vulnerable people such as women, orphans and persons living with AIDS.
THETA's main strategy is to build and support long term in-depth relationships between healers, local biomedical health workers, the local community and THETA staff based on mutual respect, openness and trust.

 Theta role - Wikipedia, the free encyclopedia
In linguistics, a theta role or θ-role is the semantic role a noun phrase plays in a sentence.
As such it is a semantic rather than a syntactic feature, in contrast to such notions as the subject of a sentence or a prepositional object.
In languages such as English which rely heavily on word order and use frequent passivization, identification of theta roles from merely syntactic clues is often impossible.

 Theta oscillations in the brain
Theta activity is one of the prominent oscillatory patterns in the EEG of animals and humans.
The mechanisms and functional role of theta oscillations is currently a hot topic, with 5 papers in the journals Nature and Science in 2002-3.
Theta is most easily recorded from the hippocampus of rodents but occurs in other cortical and subcortical structures as well, and has recently been demonstrated in the human neocortex.

 Syntax I » Themes, Patients, and Theta roles
So, when we determine the theta role, it’s based (in some sense) on the literal meaning of a sentence, and not on any kind of implication or implicature that the sentence might convey.
Defining theta roles in a satisfactory way is quite difficult to do, most of syntax proceeds with heuristics and a “we know them when we see them” approach.
It’s unlikely that this helped clarify how to define theta roles, but with luck it may have at least clarified that the situation is a bit murky with respect to determining the theta role an argument gets.

 5.1.1.1. Semantic Role Lists
Semantic roles (also known as thematic roles or theta roles) attempt to capture similarities and differences in verb meaning that are reflected in argument expression, with emergent generalizations that will contribute to the mapping from semantics to syntax.
Thus, adjuncts are not generally thought of as receiving a theta role from the verb.
The advantage of Dowty’s proposal is that thematic roles are not viewed as discrete categories, but as prototypical concepts, in line with Wittgenstein’s family resemblances and the prototypes of Rosch and her followers (cf.

Thematic role is the semantic relationship between a predicate (e.g.
Thematic roles have sometimes been associated with a theory known as Case theory, as in many languages thematic roles are reflected in the case which the noun assumes.
Thematic roles separate pleonastic (dummy) noun phrases, which lack a thematic role, such as it in it is going to rain, from meaningful noun phrases, which have one.

 Theta Roles
Theta roles are the names of the participant roles associated with a predicate: the predicate may be a verb, an adjective, a preposition, or a noun.
Theta roles play an important role in NP raising and Case theory (topics for L322).
Theta roles are closely tied to the meaning of the predicate that assigns the theta role of each argument.

 Theta role biography .ms   (Site not responding. Last check: 2007-10-12)
Other theta roles exist in the literature, but many, such as theme, tend to be more controversial.
In languages such as English which rely heavily on word order and use frequent passivization, identification of theta roles from merely syntactic cues is often impossible.
Although either the patient or agent can function as the subject of a sentence even in unmarked usages, in ergative-absolutive languages the case marking of the "subject" differs depending on the type of verb used, in a way that tends to reflect the theta role it occupies.

 The Coancestry Coefficient in Forensic Science B
Given this central role of theta in the interpretation of forensic DNA evidence, it is of interest to discuss the population genetic meaning of the parameter.
To be more accurate, N is the inbreeding effective population size, and it means that theta is increasing as though there is a probability of 1/2N of any two alleles in one generation descending from the same allele in the previous generation.
The effects of theta decrease as allele frequencies increase and are not substantial when p = 0.1 even for theta as high as 0.01.

The word 'thematic' is in REST normally abbreviated by the Greek letter theta (which of course in this medium i have to spell out).
Theta Theory assumes a fundamental asymmetry amongst syntactic categories (as we proceed, it shall become evident that similar asymmetries pervade the framework).
Having briefly addressed the possibility of adjunct NPs, whose theta- roles are typically assigned by adpositions (or by morphological case- markers, in those languages that have this option), i must now address the flip side of the issue.

 LX522 Syntax I: Questions and Answers
The light verb assigns the theta role to the subject, and the the lower verb assigns the theta roles to the other two arguments.
It seems like I "wants" to get 2 theta roles, in the sense that we seem to be assigning it two different functions in the sentence, but since we can't really be doing that, there must be a PRO taking up one of the roles, its reference controlled by I.
Perhaps another way to say this is that nothing changes with respect to the theta roles a verb (perhaps in a particular sense) assigns whether it is a main verb or an embedded verb.

Madsen, a neurosurgeon at Children's Hospital with a special interest in the treatment of epilepsy, says the recognition of theta as a neural "signature" for certain kinds of memory should help neurosurgeons avoid inadvertently excising regions key to memory and other critical brain functions.

 Linguistic Methodology
Theta-Theory concerns the relationship between thematic roles (theta-roles), such as 'agent' (the doer) and 'patient' (the do-ee), and the syntactic structure of the sentence (including 'subject', 'object', etc.).
Theta roles are essentially semantic (involve meaning), and 'subject', 'object' are syntactic roles (involve formal sentence structure).
A question word can't move to a new A-position, because these positions are assigned a thematic role under government, which would conflict with the original thematic role assigned to the word and result in a violation of the Theta-Criterion, giving one NP two thematic roles.

Notice that although the derivation in (6) countenances movement (of John) into a theta position, it does not assign two theta roles to John - the lower theta role is assigned, rather, to the larger constituent [John he] (conceivably also to the head he).
Movement into a theta position is also proposed by O'Neil (1995; 1997) and Hornstein (1999; 2001),<6> but since they do not start from a doubling structure, they also have to allow a given argument to bear more than one theta role, which the proposal illustrated in (6) does not need to do.
The double John moves into the theta position of try; it does not thereby get a second theta role, since the subject theta role of solve is born by [John PRO].

The application of a particular role to a class of verbs was based, to the extent possible, on properties outlined in Jackendoff (1983, 1990).

Although theta roles are theoretically unordered, they are generally specified in a "canonical" ordering that is thought to arise most frequently.
