INCREASED IRRITABILITY IN NITELLA DUE TO GUANIDINE

Guanidine applied to Nitella may lower the threshold of E.M.F. required to produce electrical stimulation and may give rise to trains of action currents. Its effect thus appears to be somewhat similar to that observed in animals. Rapid action currents are produced as well as "square topped"...

Sumario:Guanidine applied to Nitella may lower the threshold of E.M.F. required to produce electrical stimulation and may give rise to trains of action currents. Its effect thus appears to be somewhat similar to that observed in animals. Rapid action currents are produced as well as "square topped" action curves and transitional forms. These effects may be due in part to increased protoplasmic conductivity produced by the penetration of guanidine.
