![]() Thus, a shared tuning frequency can select neurons for membership in a circuit. When the pulse outputs are finely tuned, they function as a local “clock,” which enables the contacted neurons to synchronously communicate with each other. Synchronous pulse outputs from the circuit loops containing apical dendrites can tune subthreshold membrane oscillations of neurons they contact. The results of that simulation demonstrated that subthreshold electric pulses in these apical dendrites can be tuned to specific frequencies and also can be fine-tuned to narrow bandwidths of less than one Hertz (1 Hz). A model of the apical dendrites of these pyramidal neurons has been used to simulate the electric activity of the apical dendrite. ![]() Many layer 5 and 6 pyramidal neurons are connected to thalamic neurons in loop circuits. It is proposed that a major function of the apical dendrite is to produce sustained oscillations at a specific frequency that can serve as a common timing unit for the processing of information in circuits connected to that apical dendrite. 3Bard College at Simon’s Rock, Great Barrington, MA, United Statesīundles of relatively long apical dendrites dominate the neurons that make up the thickness of the cerebral cortex.2Stanley Laboratory of Electrical Physics, Great Barrington, MA, United States.1Department of Cognitive Sciences, University of California, Irvine, Irvine, CA, United States.
