Figure Lengend Snippet: Integrated mechanistic framework of pFUS-mediated seizure suppression. pFUS modulates neural activity through dual cellular pathways: the preferential activation of GABAergic interneurons and astrocytic mechano-transduction, leading to disrupted hypersynchrony and restored excitation–inhibition balance. These cellular effects propagate to network-level modulation, characterized by desynchronization and increased signal complexity. Ultimately, these processes drive system-level outcomes, including acute seizure reduction and long-term benefits mediated by neuroprotection.
