Summary: This study investigated changes in brain network integration/segregation during thermal pain using high temporal resolution methods. The results showed that the brain shifts from a segregated state to an integrated state when processing painful stimuli. Different brain networks were associated with pain ratings at different time points, but the association weakened when measured at lower temporal resolution. Moreover, the increased integration associated with pain can be partly explained by increased between-network connectivity. These findings highlight the importance of studying the relationship between pain and brain network connectivity at a single time point scale.

Summary: Acupuncture can reduce blood pressure and improve cognitive function, but the neural mechanism is unclear. This study used functional magnetic resonance imaging to investigate the effects of electroacupuncture and manual acupuncture on brain functional activity in hypertensive rats, and compared the differences between the two.

Summary: This study combined transcranial static magnetic field stimulation (tSMS) with resting-state functional MRI (fMRI) to investigate corticostriatal activity and found that tSMS can noninvasively modulate corticostriatal activity in humans. The results showed that the supplementary motor area (SMA) is the main region with functional connectivity to the striatum, and tSMS can modulate local activity in the SMA, adjacent sensorimotor cortex, and motor striatum. The findings also indicated that the tSMS-induced modulation of striatal activity can be primarily explained by a change in the shared activity between the modulated motor cortical areas and the motor striatum. These results suggest that corticostriatal activity can be targeted, monitored, and modulated noninvasively in humans.

Summary: This study demonstrates that acupuncture significantly increases cross-frequency coupling in specific frequency bands, impacting neural system dynamics and brain activity. Acupuncture promotes information integration and segregation within the brain, with noticeable effects in the alpha and beta bands. Multiplex network features further quantify the functional structure of cross-frequency networks, providing a new perspective on exploring brain function changes under manual acupuncture stimulation.

Summary: This study using fMRI revealed distinct activation patterns in the brain for painful and non-painful stimulation, indicating specific effects on pain perception and habituation. The findings highlight a general habituation in somatosensory processing and attention reduction, while specific effects related to pain perception were observed in the anterior midcingulate cortex.

Summary: Acupuncture at HT7 acupoint can regulate the brain reward function of rats and elevate ICSS thresholds. However, it does not affect the threshold-lowering effects produced by cocaine, indicating that it only effectively regulates the ICSS thresholds in drug-naive rats.

Summary: The default mode network (DMN) is a key structure of the brain's functional organization, and dysregulated DMN is a characteristic of neuropsychiatric disorders. This study manipulates neural synchrony, particularly alpha oscillations, and reveals a mechanistic link between alpha oscillations and DMN functioning. Transcranial alpha modulation can effectively enhance DMN connectivity and functionality.

Summary: This study investigated the brain network responses to electroacupuncture stimulation at scalp acupoints using functional magnetic resonance imaging (fMRI). The results revealed differential changes in functional connectivity in different brain networks following electroacupuncture stimulation. These findings contribute to our understanding of the neural mechanisms underlying electroacupuncture therapy.

Summary: This study examined the effects of intracranial brain stimulation on brain network dynamics in epilepsy patients. The results showed a decrease in network switching and synchrony after the stimulation, followed by a more consistent pattern over time. This change was commonly observed in cortical networks and adjacent to the electrode targets.
