Aim of study (acc. to author)

To study the gender-related influence of electromagnetic fields, similar to that emitted by mobile phones, on brain activity of human subjects.

Endpoint

effects on the neurological system: brain activity/EEG

Exposure

- mobile communications
- mobile phone

Exposure	Parameters
Exposure 1: 900 MHz Exposure duration: continuous for about 45 min	power: 64 mW mean

Exposure 1

Main characteristics

Frequency	900 MHz
Type	electromagnetic field
Exposure duration	continuous for about 45 min

Modulation

Modulation type	unspecified

Exposure setup

Exposure source	dipole antenna signal generator
Chamber	Faraday room
Setup	Subjects sat in an anatomical chair, and the antenna was fixed near their right ear at a constant distance.
Additional info	The subjects attended two sessions, with and without radiation, in random order and with an interval of two weeks.

Parameters

power	64 mW	mean	-	-	-

Exposed system:

human
partial body: right ear

Methods Endpoint/measurement parameters/methodology

effects on the neurological system: EEG during the memory task
cognitive/behavioral endpoints: auditory memory task

Investigated material:

investigation on living organism

Investigated organ system:

brain/CNS

Time of investigation:

during exposure

Main outcome of study (acc. to author)

Baseline EEG energy of males was greater than that of females, while exposure to electromagnetic fields decreased EEG energy of males and increased that of females. Memory performance was invariant to electromagnetic field irradiation exposure and gender influences. These results indicate that electromagnetic fields may exert a gender-related influence on brain activity.
