Cognitive (learning/memory) function in animals subjected to fluid percussion injury (FPI) and FPI-hemorrhagic hypotension (HH). FPI significantly impaired learning ability from 1 day through 8 wks postinjury whereupon animals recovered their learning ability (*p < .025 in comparison to sham). The superimposition of HH caused a significantly longer duration of cognitive dysfunction up to 16 wks postinjury (+p < .025 compared with sham-injured controls).
