Power spectral analysis (PSA) was used to evaluate the longitudinal overnight electroencephalographic (EEG) sleep recordings of eight subjects, between the ages of 15 and 19 years, who had sustained a minor head injury (MHI). Recordings occurred within 72 h, 6 weeks, and 12 weeks following MHI. A conditioning night preceded the first study night during(More)
The purposes of this research were to assess the cerebrovascular response of closed head-injured patients to a standardized endotracheal tube suctioning/manual hyperventilation (ETTS/MH) procedure and determine if a 5-minute rest period, following the ETTS/MH procedure, was sufficient in length to allow cerebrovascular parameters to return to(More)
This study has demonstrated widespread nerve fiber degeneration (nfd) following experimental cerebral concussion (ECC) in the rat by use of the Fink-Heimer modification of the Nauta--Gygax silver staining method for impregnation of degenerating axons. Beginning approximately 1 mm rostral to the optic chiasm and progressing caudally to the level of the(More)
