N normal phenotype
nervous system
abnormal nervous system electrophysiology ( J:141209 )
• small diameter (less than 25 um) sensory neurons lack the persistent tetrodotoxin-resistant sodium current and cannot be stimulate to up-regulated the current by intracellular dialysis of GTP-gamma-S
• however, over-expression of the human SCN11A can restore the current
