Amyloid fibrils in Alzheimer's disease differently modulate sleep and cortical oscillations in mice depending on the type of amyloid

Tomomi Sanagi, Masaki Okumura, Yuxi Lin, Shingo Kanemura, Eunyoung Moon, Yunseok Heo, Keiko Takahara, Young-Ho Lee, Tomomi Tsunematsu

This study examines how different amyloid-beta fibrils affect sleep and cortical activity in mice, revealing distinct impacts of Aβ40 and Aβ42.

Chemogenetic activation of astrocytes modulates sleep/wakefulness states in a brain region-dependent manner

Yuta Kurogi, Tomomi Sanagi, Daisuke Ono, Tomomi Tsunematsu

This study shows that chemogenetic activation of astrocytes in specific brain regions affects sleep/wakefulness states and cortical oscillations differently.

Region-specific and state-dependent astrocyte Ca2+ dynamics during the sleep-wake cycle in mice

Tomomi Tsunematsu, Shuzo Sakata, Tomomi Sanagi, Kenji F. Tanaka, Ko Matsui

This study shows that astrocyte Ca2+ levels change with sleep/wakefulness states and vary across brain regions in mice.
