Dynamical and individualised approach of transcranial ultrasound neuromodulation effects in non-human primates (2024)
Journal Article

Low-frequency transcranial ultrasound stimulation (TUS) allows to alter brain functioning with a high spatial resolution and to reach deep targets. However, the time-course of TUS effects remains largely unknown. We applied TUS on three brain targets...

Spatial organisation of the mesoscale connectome: A feature influencing synchrony and metastability of network dynamics (2023)
Journal Article

Significant research has investigated synchronisation in brain networks, but the bulk of this work has explored the contribution of brain networks at the macroscale. Here we explore the effects of changing network topology on functional dynamics in s...

Connectomes: from a sparsity of networks to large-scale databases (2023)
Journal Article
Kaiser, M. (2023). Connectomes: from a sparsity of networks to large-scale databases. Frontiers in Neuroinformatics, 17, Article 1170337. https://doi.org/10.3389/fninf.2023.1170337

The analysis of whole brain networks started in the 1980s when only a handful of connectomes were available. In these early days, information about the human connectome was absent and one could only dream about having information about connectivity i...

Nonoptimal component placement of the human connectome supports variable brain dynamics (2022)
Journal Article
Hayward, C. J., Huo, S., Chen, X., & Kaiser, M. (2023). Nonoptimal component placement of the human connectome supports variable brain dynamics. Network Neuroscience, 7(1), 254-268. https://doi.org/10.1162/netn_a_00282

Neural systems are shaped by multiple constraints, balancing region communication with the cost of establishing and maintaining physical connections. It has been suggested that the lengths of neural projections be minimized, reducing their spatial an...

Time-limited self-sustaining rhythms and state transitions in brain networks (2022)
Journal Article
Huo, S., Zou, Y., Kaiser, M., & Liu, Z. (2022). Time-limited self-sustaining rhythms and state transitions in brain networks. Physical Review Research, 4(2), Article 023076. https://doi.org/10.1103/PhysRevResearch.4.023076

Resting-state networks usually show time-limited self-sustaining oscillatory patterns (TLSOPs) with the characteristic features of multiscaled rhythms and frequent switching between different rhythms, but the underlying mechanisms remain unclear. To... Read More about Time-limited self-sustaining rhythms and state transitions in brain networks.

Dynamic reconfiguration of macaque brain networks during natural vision (2021)
Journal Article

Natural vision engages a wide range of higher-level regions that integrate visual information over the large-scale brain network. How interareal connectivity reconfigures during the processing of ongoing natural visual scenes and how these dynamic fu...
