摘要： The present invention provides a method for improving cognitive performance that encompasses all of: sense; perception; recognition; judgment; and action or suppression; and is based on a higher brain function. The method for improving cognitive performance of the present invention includes administering astaxanthin and/or an ester thereof to an individual. The cognitive performance is, for example, at least one selected from the group consisting of judging ability, spatial attention-allocating ability, concentration on the recognition of surroundings, and agility as determined by speed and/or accuracy of a body reaction which requires a higher brain function.

摘要： An optical module including a transimpedance amplifier capable of realizing a high-speed and high-quality receiving operation is provided. A transimpedance amplifier includes: a pre-amplifier using a single-end current signal as an input and converting the single-end current signal to a single-end voltage signal; an automatic decision threshold control detecting a center electric potential of the single-end voltage signal serving as an output of the pre-amplifier; a post-amplifier differentiating and amplifying the single-end voltage signal of the output of the pre-amplifier; and a power circuit supplying power to the pre-amplifier. Particularly, in accordance with an input voltage signal or an output voltage signal of the pre-amplifier, the power circuit outputs a varied current that flows to a supply terminal of the pre-amplifier and a varied current having a phase opposite to that of the varied current. Thus, the power supply current change is cancelled out.
