Based on the similarity of chaos in human brain and Chua's circuit

we propose the methods to model human brain with Chua's circuit.With the simulation of Multisim 10

we set voltages across resistor

R

1

as original signals.Also

Analogous definite integral

Lyapunov

Micro-segmented windows and P values are applied to gain data window.Then

minimum mean power of

R

1

(

P

R1min

:1.5610

-4

W) is discovered after tuning inductance

L

and nonlinear-resistor parameter

R

5

.Furthermore

we suppose

P

R1min

as log-base

and calculate the new indexes for each power of

R

1

as reference values.After compared with previous indexes of brain power consumption(BPC)in frontal lobe at cognitive states of calmness

honesty

or lying(BPC at smile as base)

two-set indexes equal to each other.According to actual BPC

and with Chua's circuit corresponding to minimum mean power

P

R1min

we accomplish human brain model in frontal lobe at cognitive states of calmness

honesty

lying and smile.This work will provide novel thinking for nonlinear modeling of human brain.
