    The biologically relevant parameter in nerve impulse trains (1970)
    Springer
    Biological cybernetics 6 (1970), S. 168-170

    ISSN: 1432-0770

    Topics: Biology , Computer Science , Physics
    Notes: Summary An experiment is described, the results of which indicate that impulse rate is the information carrying parameter of impulse trains. The demodulation of such information occurs by low-pass filtering. This conceptual model is compatible with all the features of synaptic transmission. The implications of this model for the transmission of information in integrative neurons is discussed.

    Cation selectivity of the resting membrane of squid axon (1972)
    Springer
    The journal of membrane biology 9 (1972), S. 373-384

    Notes: Summary Permeability constant ratios among monovalent cations were studied in the resting membrane of a giant axon of a Pacific squid,Loligo opalescens, by observing the relationship between the membrane potential and the ion concentration. The average permeability ratios are: Tl, 1.8; K, 1.0; Rb, 0.72; Cs, 0.16; Na, 〈0.08; Li, 〈0.08. These permeability ratios suggest that neither valinomycin nor nonactin are adequate models for the sites producing the resting permeability in the axonal membrane. Cyclic polyetherbis(t-butyl cyclohexyl) 18-crown-6 does not increase the permeability ratioP Cs/P K except when applied at concentrations (5×10−5 m) at which the surfactant properties of this molecule may become significant.
