how are lfp's produced?
Signals travel down the axon of the neutron, when they reach the synapse, neurotransmitters are transmitted across, this excites/ opposite, this creates a current through the neutron like a dipole, these currents from the dipoles combine= LFP

In EEG, what increases LFP?
If the dendrites are aligned similarly, their closeness to scalp, larger number of synapses, the fact that EEG ignores deeper structures EM
