The paper introduces OCaMP, an orange fluorescent calcium indicator that improves sensitivity and performance compared to existing green and red indicators for neural imaging.

The paper investigates the dual function of pannexin-1 as an ion channel and anandamide transporter, showing that the N-terminal helix regulates this switch.

The paper shows that astrocyte Ca2+ signaling amplifies sustained functional hyperemia in awake mice, but not brief responses, through distinct mechanisms.
