Interactions among neural networks for behavior.

abstract：:Most high-level sensory neurons have complex, nonlinear response properties; a comprehensive characterization of these properties remains a formidable challenge. Recent studies using complex sensory stimuli combined with linear and nonlinear analyses have provided new insights into the neuronal response properties in ...

abstract：:The plasticity of the nervous system is due to the ability of neurons to change their properties by altering the function of their proteome. A major mechanism for this is through altering the amount of proteins by regulating their translation. In this review, we focus on recent advances in the elucidation of the mecha...
