Schedule of experimental procedures. Timeline of the experimental protocol for (1) injection of blood into the subarachnoid space (SAs) and (2) perforation of the anterior cerebral artery (ACA). Rats underwent surgery for implantation of temperature recording devices on Day 0. On day 8, following 7 days of recovery from surgery, one hour of baseline core temperatures were recorded at 15 min intervals, followed by the procedure for blood injection into the SAs or perforation of the ACA. Core temperature was then monitored for 2 h, before perfusion, to assess the occurrence of NF.
