In resting-state EEG, the ratio between frontal power in the slow theta frequency band and the fast beta frequency band (the theta/beta ratio, TBR) has previously been negatively related to attentional control. Also, increased theta and reduced beta power were observed during mind wandering (MW) compared to episodes of focused attention. Thus, increased resting-state frontal TBR could be related to MW, suggesting that previously observed relationships between TBR and attentional control could reflect MW episodes increasing the average resting state TBR in people with low attentional control.

We proposed an integration hypothesis of mind wandering in which the tendency of mind wandering is only related to working memory capacity (WMC) when a self-regulation process is required (i.e., under...
Recent claims that people spend 30-50% of their waking lives mind wandering (Killingsworth & Gilbert, 2010; Kane et al., 2007) have become widely accepted and frequently cited. While acknowledging att...
There is accumulating evidence which shows that mind wandering may be increased within automated environments. This is particularly concerning when considering the negative effect of mind wandering on...
In recent years, several laboratory studies have indicated that healthy older adults exhibit a reduction in mind-wandering frequency compared with young adults. However, it is unclear if these finding...
Recent research has indicated that reducing the difficulty of a task by increasing the predictability of critical stimuli produces increases in intentional mind wandering, but, contrary to theoretical...
This study will investigate the effects of an EEG theta/beta ratio Neurofeedback training using a case series multiple baseline design. Twelve participants will be assigned to one of three...
The purpose of this investigation is data pilot study of the effect of theta frequency stimulation of the vagus nerve on cognitive performance in patients with refractory epilepsy. We will...
The investigators conducted a mindfulness training intervention in older adults aimed at examining the effects of brief mindfulness training on mind wandering as well as the cognitive and ...
The goal of this double-blind sham controlled study is to evaluate the effeicacy of continuous theta burst stimulation to the frontal pole as a tool to decrease drug cue reactivity and imp...
Repetitive transcranial magnetic stimulation has been shown to be moderately effective in the treatment of major depression. Theta burst stimulation (TBS) is a new form of rTMS that may ex...
Members of the beta-globin family. In humans, they are encoded in a gene cluster on CHROMOSOME 11. They include epsilon-globin, gamma-globin, delta-globin and beta-globin. There is also a pseudogene of beta (theta-beta) in the gene cluster. Adult HEMOGLOBIN is comprised of two ALPHA-GLOBIN chains and two beta-globin chains.
Members of the alpha-globin family. In humans, they are encoded in a gene cluster on CHROMOSOME 16. They include zeta-globin and alpha-globin. There are also pseudogenes of zeta (theta-zeta) and alpha (theta-alpha) in the cluster. Adult HEMOGLOBIN is comprised of 2 alpha-globin chains and 2 beta-globin chains.
The ratio of two odds. The exposure-odds ratio for case control data is the ratio of the odds in favor of exposure among cases to the odds in favor of exposure among noncases. The disease-odds ratio for a cohort or cross section is the ratio of the odds in favor of disease among the exposed to the odds in favor of disease among the unexposed. The prevalence-odds ratio refers to an odds ratio derived cross-sectionally from studies of prevalent cases.
A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).

Infection of the FRONTAL BONE often as a complication of FRONTAL SINUSITIS or trauma to the frontal bone and skull. It is characterized by subperiosteal abscess with OSTEOMYELITIS.
