[Retracted] Propofol Causes Consciousness Loss by Affecting GABA-A Receptor in the Nucleus Basalis of Rats

Figure 4

EEG and energy spectrum analysis of prefrontal cortex in rats with different anesthetic doses of propofol. (a) Record of the high-frequency low-level alpha wave in the awake state and the energy spectrum in the right. (b) Low doses of propofol (50 mg/kg/h) increase the slow wave energy as an increase in delta wave energy, expressed in black. (c) indicates that a medium dose of propofol (60 mg/kg/h) increases the energy in the 0-10 Hz band, reducing the energy of the 50-60 HZ fast wave, producing a mild inhibition, indicated in black. (d) indicates a dose of 70 mg/kg/h.

(a) Awake immobility

(b) Propofol 50 mg/kg/h IV

(c) Propofol 60 mg/kg/h IV

(d) Propofol 70 mg/kg/h IV
