OPTIMAL STIMULUS SHAPES FOR NEURONAL EXCITATION.

Optimal stimulus shapes for neuronal excitation.

An important problem in neuronal computation is to discern how features of stimuli control the timing of action potentials.One aspect of this problem is to determine how an action potential, or spike, can be elicited with the least energy cost, e.g., a minimal amount of applied current.Here we show in the Hodgkin & Huxley model of the action potent

Mitochondrial DNA Corroborates the Genetic Variability of Clarias Catfishes (Siluriformes, Clariidae) from Cameroon

The airbreathing walking catfish (Clariidae: Clarias) comprises 32 species that are endemic to African freshwater systems.The species-level identification of this group is challenging due to their complex taxonomy and polymorphism.Prior to this study, the biological and ecological studies were restricted to a single species, Clarias gariepinus, res
