“…If so, dynamic patterns of coherence across these brain structures may be a critical component of the decision and learning process of goal-directed behaviors. Task-selective, cross-structure relation-ships have been reported for the hippocampus and amygdala and for pairs of cortical areas (8,(39)(40)(41). Our findings suggest that cross-structure coherence patterns are built through experience and may be required for learning and that these changing coherence patterns may influence the degree of coordination with which the striatum and the hippocampus operate during goal-directed behaviors.…”

The striatum and hippocampus are conventionally viewed as complementary learning and memory systems, with the hippocampus specialized for fact-based episodic memory and the striatum for procedural learning and memory. Here we directly tested whether these two systems exhibit independent or coordinated activity patterns during procedural learning. We trained rats on a conditional T-maze task requiring navigational and cue-based associative learning. We recorded local field potential (LFP) activity with tetrodes chronically implanted in the caudoputamen and the CA1 field of the dorsal hippocampus during 6 -25 days of training. We show that simultaneously recorded striatal and hippocampal theta rhythms are modulated differently as the rats learned to perform the T-maze task but nevertheless become highly coherent during the choice period of the maze runs in rats that successfully learned the task. Moreover, in the rats that acquired the task, the phase of the striatal-hippocampal theta coherence was modified toward a consistent antiphase relationship, and these changes occurred in proportion to the levels of learning achieved. We suggest that rhythmic oscillations, including theta-band activity, could influence not only neural processing in cortico-basal ganglia circuits but also dynamic interactions between basal ganglia-based and hippocampus-based forebrain circuits during the acquisition and performance of learned behaviors. Experience-dependent changes in coordination of oscillatory activity across brain structures thus may parallel the well known plasticity of spike activity that occurs as a function of experience.basal ganglia ͉ hippocampus ͉ local field potential ͉ oscillations ͉ striatum T he striatum and the hippocampus are both forebrain structures implicated in the learning and memory of behavioral sequences, but behavioral sequences of different sorts. The striatum, as part of basal ganglia circuitry, is associated with learning sequences of actions that make up goal-directed procedures and habits (1-4). The hippocampus and adjoining cortical structures are recognized as critical for encoding and storing sequences on the basis of episodic, context-cued events (5-8). Lesion studies have dissociated striatum-dependent and hippocampus-dependent forms of learning and memory (9-11), supporting the view that these systems work independently or even competitively. In humans, there is evidence that one system can substitute for another (12). Other evidence, however, suggests that ''hippocampal'' deficits can follow damage in regions of the dorsal striatum interconnected with hippocampal/limbic circuits (13,14). Furthermore, part of the ventral striatum receives direct projections from the hippocampus.Rhythmic activity in the theta range (Ϸ7-14 Hz in the rodent) has been proposed to be crucial for mnemonic coding in the hippocampus and related limbic structures. Pathways interconnecting the hippocampus and neocortex are thought to use these rhythms for transferring and coordinating neural representations in cort...

“…Because coupling in the theta-frequency range between the medial frontal cortex and hippocampus in rodents has been reported (Hyman et al 2005;Jones and Wilson 2005b;Siapas et al 2005;Young and McNaughton 2009), such functional coupling may also exist in the primate. In electroencephalographic studies in human subjects, a similar correlation of theta oscillations is reported between the frontal leads and the temporal and posterior leads during working memory tasks (Moore et al 2006;Sarnthein et al 1998;Sauseng et al 2004Sauseng et al , 2005Sauseng et al , 2006Weiss et al 2000), suggesting intercortical functional coupling. In addition, although we focused our analysis on oscillatory activities in the theta-frequency range, there also seems to be modulation in different frequency bands (e.g.,, alpha and beta bands in area 46v in Fig.…”

“…Fm theta oscillations can be observed in various kinds of situations demanding attention, including mental calculation, working memory tasks, visuospatial tasks, verbal tasks, musical imagination, video games, and meditation (for review, see Mitchell et al 2008). There is evidence suggesting that Fm theta oscillations are correlated with theta oscillations in the temporal or posterior regions in certain conditions (Moore et al 2006;Sarnthein et al 1998;Sauseng et al 2004Sauseng et al -2006Weiss et al 2000). Because coupling of neural activities in the theta-frequency range has been reported between the rodent's medial frontal cortex and hippocampus (Hyman et al 2005;Jones and Wilson 2005a,b;Siapas et al 2005;Young and McNaughton 2009), it is an intriguing question whether Fm theta oscillations are related to theta oscillations in the human hippocampus.…”

we introduced a monkey model for human frontal midline theta oscillations as a possible neural correlate of attention. It was based on homologous theta oscillations found in the monkey's prefrontal and anterior cingulate cortices (areas 9 and 32) in a self-initiated handmovement task. However, it has not been confirmed whether theta activity in the monkey model consistently appears in other situations demanding attention. Here, we examined the detailed properties of theta oscillations in four variations of forewarned reaction time tasks with warning (S1) and imperative (S2) stimuli. We characterized the theta oscillations generated exclusively in areas 9 and 32, as follows: 1) in the S1-S2 interval where movement preparation and reward expectation were presumably involved, the theta power was higher than in the pre-S1 period; 2) in the no-go trials of go/no-go tasks instructed by S1, the theta power in the S1-S2 interval was lower than in the pre-S1 period in an asymmetrical reward condition, whereas it was moderately higher in a symmetrical condition; 3) the theta power after reward delivery was higher than in the unrewarded trials; 4) the theta power in the pre-S1 period was higher than in the resting condition; and 5) when the monkey had to guess the S1-S2 duration internally without seeing S2, the theta power in the pre-S1 period was higher than in the original S1-S2 experiment. These findings suggest that attentional loads associated with different causes can induce the same theta activity, thereby supporting the consistency of attentiondependent theta oscillations in our model.

“…During certain behaviors, the supramammillary nucleus regulates the frequency of theta activity, and Aranda et al [15] recently found that lesions of the supramammillary nucleus in rats led to reduced BI. Very few direct tests of the updated Gray-McNaughton BIS model in humans exist, but a recent electroencephalogram (EEG) study by Moore et al [16] did find increased theta power and coherence at points of conflict, as well as during response in a go-no-go type of task.…”

Behavioral inhibition (BI) during early childhood has been associated with subsequent development of anxiety disorders. However, understanding of the neuroanatomical substrates of BI in humans generally has not kept pace with that of anxiety disorders. Recent interpretations and implementations of Gray's and Kagan's concepts of BI are examined from the perspective of current neurobiological models. Particular attention is given to evidence pointing to conceptual and operational limitations of self-report scales purported to measure trait BI in adults, and especially to inconsistent correlations between such behavioral inhibition system (BIS) scores and amygdala and autonomic responses to fear- or startle-inducing stimuli. Evidence showing a dissociation of both BI and trait anxiety from the amygdala is considered. Possible reasons for the poor association between BIS and trait anxiety self-report scale scores and predicted physiological outputs of the BIS are identified. Reasons to distinguish between the neural bases of BI as against trait anxiety also are discussed. The need to critically examine the role of the amygdala in BI and trait anxiety, as well as to consider other brain areas that appear to be involved in subserving these emotional traits, is emphasized.
