CFNS (AM)

CFNS (AM) likely refers to the abbreviation for the Canadian Foundation for Neuroscience, followed by the designation (AM) indicating Amplitude Modulation. Without further context, it's difficult to determine the specific intended meaning, but it most likely refers to a radio broadcast originating from or related to the Canadian Foundation for Neuroscience.

Amplitude Modulation (AM) is a type of radio transmission in which the amplitude of the carrier wave is varied in proportion to the instantaneous amplitude of the modulating signal. AM radio is commonly used for broadcasting, particularly for talk radio and news programming.

Therefore, CFNS (AM) most likely represents a radio station, potentially affiliated with or supporting the Canadian Foundation for Neuroscience, broadcasting using Amplitude Modulation.
