Legislation for Ukraine's public health: the current situation and paths to further development.

The paper contains the findings of an analytical study of the current national health care legislation of Ukraine and identification of priority areas in its further development. One of the key objectives of the above study was to identify the compliance of the national healthcare legal framework with the approaches to health policy formation, which are set out in the documents of global and European regional international organizations, and to assess whether the national legislation includes that spectrum of functions that are to be covered by the health care legislation. The analysis showed that Ukraine's national healthcare legislation is rather strong and well developed. Though the national healthcare legislation is mostly in line with international approaches to the state health care policy formulation, the issue of enforcing already adopted laws and by-laws and ensuring their compliance by all legally established bodies, including state authorities and self-governments, citizens, NGOs, etc, is problematic.

Color signals in human motion-selective cortex.

The neural basis for the effects of color and contrast on perceived speed was examined using functional magnetic resonance imaging (fMRI). Responses to S cone (blue-yellow) and L + M cone (luminance) patterns were measured in area V1 and in the motion area MT+. The MT+ responses were quantitatively similar to perceptual speed judgments of color patterns but not to color detection measures. We also measured cortical motion responses in individuals lacking L and M cone function (S cone monochromats). The S cone monochromats have clear motion-responsive regions in the conventional MT+ position, and their contrast-response functions there have twice the responsivity of S cone contrast-response functions in normal controls. But, their responsivity is far lower than the normals' responsivity to luminance contrast. Thus, the powerful magnocellular input to MT+ is either weak or silent during photopic vision in S cone monochromats.
