Neurosurgeons are in a unique position to shed light on the neural basis for consciousness, not only by their clinical care of patients with compromised states of consciousness, but also by employing neurostimulation and neuronal recordings through intracranial electrodes in awake surgical patients, as well as during stages of sleep and anethesia. In this review, we discuss several aspects of consciousness, i.e.

Object: Despite a history of safety and efficacy, spinal anesthesia is rarely used in lumbar surgery. Application of regional anesthetics is widely preferred for lower-extremity surgery, but general anesthesia is used almost exclusively in spine surgery, despite evidence that spinal anesthesia is as safe and may offer some advantages.
Methods: In this case-controlled study the authors analyzed outcomes obtained in 400 patients in whom either spinal anesthesia or general anesthesia was induced to perform a lumbar decompression.

Five adult male subjects vocally matched the pitches of tones in a steady-state tone matching task (SSTMT) and vocally shadowed frequency changes in a frequency modulated tone matching task (FMTMT). Matching was done in both a normal condition and a condition of topical anesthesia of the laryngeal mucosa. Pitch matching accuracy was not seriously altered in the anethesia condition, but anesthetized subjects required more time and had slower velocities in effecting transitions between tones on the FMTMT, as compared to normal.
