Attention is a cognitive and behavioral process that selectively focuses on the individual aspects of subjective or objective information. It has been shown that transcranial magnetic stimulation of the brain, or rTMS, can affect the networks of attention in the brain of some peoples. In this study we report the effects of our experimental setup(Beta-1 Device) on human brain. Current research shows the influences of our setup on human concentration and attention. Respected to the low number of sessions of this stimulation using the beta1 device and the significant effect of this stimulation, the beta1 system can be helpful in the treatment or improvement of attention deficit disorders. It is suggested that the effectiveness of this machine in increasing attention and focus should be studied by repeating this research and increasing the number of magnetic stimulation sessions of the brain. Due to the results of the previous researches in the stimulation of the DLPFC area and its relevance with the recovery of depression, the effect of stimulation of brain by this device on depression is expected. In the present study, the final scores of attention and visual and auditory focus in the IVA test were considered. It seems that repeating the research and measuring the different components of attention mentioned in this test can illuminate the dark angles of the present study.

Abstract We are just beginning to understand how spaceflight may impact brain function. As NASA proceeds with plans to send astronauts to the Moon and commercial space travel interest increases, it is critical to understand how the human brain and peripheral nervous system respond to zero gravity. Here, we developed and refined head-worn transcranial magnetic stimulation (TMS) systems capable of reliably and quickly determining the amount of electromagnetism each individual needs to detect electromyographic (EMG) threshold levels in the thumb (called the resting motor threshold (rMT)). We then collected rMTs in 10 healthy adult participants in the laboratory at baseline, and subsequently at three time points onboard an airplane: (T1) pre-flight at Earth gravity, (T2) during zero gravity periods induced by parabolic flight and (T3) post-flight at Earth gravity. Overall, the subjects required 12.6% less electromagnetism applied to the brain to cause thumb muscle activation during weightlessness compared to Earth gravity, suggesting neurophysiological changes occur during brief periods of zero gravity. We discuss several candidate explanations for this finding, including upward shift of the brain within the skull, acute increases in cortical excitability, changes in intracranial pressure, and diffuse spinal or neuromuscular system effects. All of these possible explanations warrant further study. In summary, we documented neurophysiological changes during brief episodes of zero gravity and thus highlighting the need for further studies of human brain function in altered gravity conditions to optimally prepare for prolonged microgravity exposure during spaceflight.

Phonologically similar items (mell, rell, gell) are more difficult to remember than dissimilar items (shen, floy, stap), likely because of mutual interference of the items in the phonological store. Low-frequency transcranial magnetic stimulation (TMS), guided by functional magnetic resonance imaging (fMRI) was used to disrupt this phonological confusion by stimulation of the left inferior parietal (LIP) lobule. Subjects received TMS or placebo stimulation while remembering sets of phonologically similar or dissimilar pseudo-words. Consistent with behavioral performance of patients with neurological damage, memory for phonologically similar, but not dissimilar, items was enhanced following TMS relative to placebo stimulation. Stimulation of a control region of the brain did not produce any changes in memory performance. These results provide new insights into how the brain processes verbal information by establishing the necessity of the inferior parietal region for optimal phonological storage. A mechanism is proposed for how TMS reduces phonological confusion and leads to facilitation of phonological memory.
