Chronic subthreshold intermittent theta burst stimulation promotes structural axon initial segment plasticity in cortical neurons

This study shows that chronic intermittent theta burst stimulation (iTBS) induces axon initial segment (AIS) plasticity in cortical neurons, both in vitro and in vivo, suggesting non-synaptic mechanisms of rTMS effects.

Assessing Brain-Behaviour Coupling in Non-invasive Brain Stimulation Using Reliable Change Indices: Evidence from pre-Supplementary Motor Area - right Inferior Frontal Gyrus transcranial Alternating Current Stimulation

This study evaluates brain-behavior coupling in non-invasive brain stimulation using reliable change indices and finds no significant association between tACS-induced connectivity changes and response inhibition.

Repeated application of bifocal transcranial alternating current stimulation (tACS) improves network connectivity and driving performance: a double-blind sham control study

This study shows that repeated bifocal tACS improves functional connectivity and general driving performance but not response inhibition in young adults.

Characterisation of the axon initial segment and intrinsic excitability in the sub-acute phase post-ischemic stroke

This study examines AIS structure and intrinsic excitability in the sub-acute phase post-ischemic stroke in mice, finding preserved AIS structure but reduced excitability and sex-dependent changes in contralesional hemisphere.

Dual-site transcranial alternating current stimulation over the primary motor cortices increases interhemispheric inhibition and improves bimanual dexterity: A triple-blind, randomised, sham-controlled study

This study shows that dual-site tACS over M1s increases interhemispheric inhibition and improves bimanual dexterity, suggesting modulation of M1-M1 connectivity rather than oscillatory coupling.

Comparison of online and offline applications of dual-site transcranial alternatingcurrent stimulation (tACS) on functional connectivity between pre-supplementarymotor area (preSMA) and right inferior frontal gyrus (rIFG) for improving responseinhibition

This study compares online and offline dual-site tACS on functional connectivity and response inhibition, finding that online tACS increases connectivity and improves inhibition, while offline tACS improves inhibition through different mechanisms.

The Effects of Dual-Site Beta tACS over the rIFG and preSMA on Response Inhibition in Young and Older Adults

This study investigates the effects of dual-site beta tACS on response inhibition in young and older adults, finding no significant phase-dependent improvements or changes in connectivity.

Characterising the balance between short-interval intracortical inhibition and short-interval intracortical facilitation in younger and older adults.

The paper compares short-interval intracortical inhibition and facilitation in younger and older adults, finding age-related differences in their balance and association with manual dexterity.
