Dopamine diffusion after microwave fixation at 986 MHz
Abstract:
It has been previously demonstrated by us that microwave irradiation at 2450 MHz causes diffusion of dopamine from rat brain regions of high dopamine concentration to contiguous regions low in dopamine. Because we have found that the heating pattern at 986 MHz is opposite to that seen at 2450 MHz, we attempted in the present study to eliminate DA diffusion by heating at 986 MHz. However, dopamine levels were elevated in frontal and parietal cortex, remainder of cortex, and amygdala after sacrifice by microwave irradiation at 986 MHz. Norepinephrine levels were unaffected by sacrifice method. Microwave-induced diffusion of certain substances must be considered in the interpretation of regional neurochemical data.
Insights
Microwave irradiation at 986 MHz unexpectedly increased dopamine levels in specific rat brain regions. This finding highlights the need to consider microwave-induced diffusion when interpreting neurochemical data.
Area of Science:
- Neuroscience
- Biochemistry
- Electromagnetics
Background:
- Previous research showed 2450 MHz microwave irradiation causes dopamine diffusion in rat brains.
- The heating pattern at 986 MHz is opposite to that at 2450 MHz.
Purpose of the Study:
- To investigate if 986 MHz microwave irradiation could prevent dopamine diffusion.
- To examine the effects of 986 MHz microwave irradiation on regional dopamine and norepinephrine levels.
Main Methods:
- Rats were sacrificed using 986 MHz microwave irradiation.
- Regional dopamine and norepinephrine levels were measured post-irradiation.
Main Results:
- Dopamine levels were elevated in the frontal cortex, parietal cortex, remainder of cortex, and amygdala.
- Norepinephrine levels remained unaffected by the 986 MHz microwave irradiation sacrifice method.
Conclusions:
- 986 MHz microwave irradiation did not eliminate dopamine diffusion and instead caused increases in specific brain regions.
- Microwave-induced diffusion effects must be considered when interpreting regional neurochemical data from microwave-sacrificed animals.
