Simulated local field potential (LFP) and blood-oxygen-level dependent (BOLD).

(A) Three different inputs to each neuron were simulated: a broadband, random input with a small positive offset (C¹), an oscillatory input with a time scale of 40 Hz to 60 Hz (C²), and a negative input with a time scale of 10 Hz (C³). (B) The 3 inputs (C¹, C², C³) were summed in each neuron to produce the total input to the neuron. (C) The total input was passed through a leaky integrator to produce the dendritic dipole current (I_i). The LFP was simulated by summing the dendritic currents. (D) The BOLD signal was simulated by taking the power of the dendritic current for each neuron and then summing across neurons.
