The realization that different behavioural and perceptual states of the bra
in are associated with different brain rhythms has sparked growing interest
in the oscillatory behaviours of neurons. Recent research has uncovered a
close association between electrical oscillations and resonance in neurons.
Resonance is an easily measurable property that describes the ability of n
eurons to respond selectively to inputs at preferred frequencies. A variety
of ionic mechanisms support resonance and oscillation in neurons. understa
nding the basic principles involved in the production of resonance allows f
or a simplified classification of these mechanisms. The characterization of
resonance and frequency preference captures those essential properties of
neurons that can serve as a substrate for coordinating network activity aro
und a particular frequency in the brain.
