Probably, this effect could be produced through an effect upon the neuronal excitability by ionic channel modulation, since the voltage gated [K.sup.+] channels from the Kv family are involved in the neuronal signaling, changing the discharge threshold of action potential, its frequency, etc.
The reason behind the development of SD is not fully clear, but it might result from differential ionic channels activities in various areas of the brain as a consequence of areal metabolic-perfusion mismatches (7).
Ionic channels were created by the hydrophilicity of quaternary ammonium ionic and the hydrophobic of aliphatic pendant.
