| Abstract | ||
| The electroencephalogram (EEG) is a unique and valuable measure of the brain’s electrical functions. It is a graphic display of a difference in voltages from two sites of brain function recorded over time. Physical, chemical and mechanical stimulators appear as wave frequency, action potential amplitude changes which are reaching different areas in the brain. Each area is responsible to record a certain type of stimulator whether it is chemical that is received by smelling, and test senses, physical stimulator by hearing, , and vision senses, or touching stimulator. This research is concentrated on the determination of the most sensitive areas (the correct channels of electrodes placement system) of the brain that are responsible to receive the highest chemical stimulation due to the action of Lavender perfume stimulator (Lavender perfume with concentration of 50 % ), for normal males and females subjects for smelling sense. Ten males and the same numbers of females all subjects selected within the age range between (25- 30) years old. It has been found that T3 and T4 are the best channels connections for smelling sense for both male and female, and that the mean relative action potential (The ratio of action potential amplitude after to that before exposure of perfume stimulation) for males are higher than that for females, these results reflect that males are more sensitive than females in this type of perfume and may be it is not in other type, and the mean relative action potential amplitude for the channels T3, T4, T5, T6, P3, and P4 are 2.05, 1.80, 1.12, 1.20, 1.10, and 1.10 for males and 1.96, 1.76, 1.12, 1.11, 1.09, 1.09 for females respectively. | ||
