“…We then used Granger causality spectra to measure directional influences among recording sites, ascertaining that the dominant causal influences occurred in the same part of the beta-frequency range (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) indicated by coherence analysis. The patterns of significant beta-frequency coherence and Granger causality are summarized in the graphs shown in Figure 2.…”

A framework is presented for quantifying functional network organization in the brain by spectral analysis based on autoregressive modeling. Local field potentials (LFPs), simultaneously recorded from distributed sites in the cerebral cortex of monkeys, are treated as signals generated by local neuronal assemblies. During the delay period of a visual pattern discrimination task, oscillatory assembly activity is manifested in the LFPs in the beta-frequency range (14-30 Hz). Coherence analysis has shown that these oscillations are phase synchronized in functional networks in the sensorimotor cortex in relation to maintenance of contralateral hand position, and in the visual cortex in relation to anticipation of the visual stimulus. Granger causality analysis has revealed information flow in the sensorimotor network that is consistent with a peripheral sensorimotor feedback loop, and in the visual network that is consistent with top-down anticipatory modulation of assemblies in the primary visual cortex.

“…While occasional use of cannabis does not seem to significantly impair the ability to filter irrelevant auditory stimuli during acute intoxication [33], chronic use does. For example, event related potentials (ERPs) are known to be temporal representations of electrical brain activity related to sensory, motor, and cognitive events [65]. In a series of studies done by Solowij and colleagues [64,66,67], ERPs were recorded from long-term cannabis users during a complex auditory selective attention task, which were compared with the performance of nonuser controls.…”

This chapter is aimed at summarizing the existing literature with respect to the subjective and objective cognitive profiles associated with marijuana use. Although subjective reports of marijuana use include feelings of relaxation and increased creativity, the altered state of consciousness and reduced inhibitory and executive cognitive functions may be enough to cause impairment in daily functioning. However, a chronically high level of consumption for an extended period of time is likely to result in increased risk of developing impairments such as affective dysregulation, inefficient cognitive control, underachievement, lower estimated intellectual capacity, and increased potential for additional drug use.

“…The contingent negative variation (CNV) is an endogenous ERP component characterized by a large negative shift reflecting response anticipation that occurs between a warning stimulus (S1) and an imperative stimulus (S2; Walter et al, 1964;Tecce, 1972;Tecce and Cattanach, 1993;Bressler and Ding, 2006). The component has been further decomposed into two subcomponents: initial CNV (iCNV) and terminal CNV (tCNV; Loveless and Sanford, 1974;Birbaumer et al, 1990).…”
