A series of papers explored the hypothesis that the apical dendrite is not “just another dendrite” but has its own special functions (2001, 2002, 2005, 2006, 2007). A formal description of a theory of electric resonance in apical dendrites appeared in an article by Kasevich & LaBerge (2011), which shows how an apical dendrite can fine tune its own membrane oscillations to a specific peak frequency, and narrow the width of the resonance curve around this peak to less than 1 Hz. This refinement enables its associated cortical circuit to generate a specific resonant (“carrier”) frequency by which the circuit can separate its signaling from that of other circuits. A more recent article (LaBerge & Kasevich, 2013) describes signaling by neurons as the neural correlate of objective information processing and resonating in clusters of apical dendrites as the neural correlate of subjective impressions (e.g., impressions of sounds, colors, and feelings). These articles provide theoretical support for the hypothesis that apical dendrite resonance supplements neural signaling as a major mode of neural function.
