A Theory of Nerve-Conduction.
fore be stated that, notwithstanding the many difficulties in the way of such studies among primitive peoples, there have been made some serious beginnings in this very important line of anthropological investigation. As to detailed results, nothing can be said until a careful and necessarily tedious elaboration of the data is completed. The third main object of anthropological field work under...
متن کاملOn the cable theory of nerve conduction.
Conduction of an impulse in the nonmyelinated nerve fiber is treated quantitatively by considering it as a direct consequence of the coexistence of two structurally distinct regions, resting and active, in the fiber. The profile of the electrical potential change induced in the vicinity of the boundary between the two regions is analyzed by using the cable equations. Simple mathematical formula...
متن کاملConduction in Nerve Fibres
Data by E. A. Blair and Erlanger on the voltage-capacity curves and the nerve impulse velocities of each of several fibres in the same nerve trunk are related to Rashevsky's equation for the velocity of transmission in nerve. The results lend support to Rashevsky's analysis. Other empirical relations between the velocity and the parameters of the excitation equations indicate the correctness of...
متن کاملA normative study of nerve conduction
The temporal branch of the facial nerve is particularly vulnerable to traumatic injuries during surgical procedures. It may also be affected in clinical conditions. Electrodiagnostic studies may add additional information about the type and severity of injuries, thus allowing prognostic inferences. The objective of the present study was to develop and standardize an electrophysiological techniq...
متن کاملMotor Nerve Conduction Studies
tion techniques, it is important to pursue more specialized methods of evaluating the peripheral nervous system. Additionally, nerves requiring needle excitation and less commonly studied nerves are of importance. From time-to-time patients may present with lesions affecting specific sensory branches that yield small amplitude responses or require averaging techniques to better define the desir...
