A New Functional Transcranial Doppler Spectroscopy (fTCDS) Study of Cerebral Asymmetry During Neuro-Cognitive Functions in Men and Women

摘要: The perception of light underlies the processes cognitive brain function. However, characterizations neuroadaptational that relates to physical quality light, particularly those implicated in color processing remains largely unknown. Simultaneous contrast and constancy have been identified as memory associated with [1-8]. is phenomenon surrounding colors profoundly influence perceived [1,9]. mechanism simultaneous has described wavelength-differencing, implying ability differ‐ entiate dominant wavelength [10]. Wavelength-differencing involves wavelength-encoding main effect at subcortical peaks, energy-encoding effects cortical peaks [11]. On other hand, frequency-differencing refers differentiate frequency (the inverse wavelength) energyencoding [11, 12]. Genetic studies suggest genderrelated differences vision primates. Whereas both trichromatic dichromatic occurs among female monkeys, males appear exclusively [13]. It was proposed that, unlike humans, squirrel monkeys only a single photopigment locus on X chromosome
