From: Exposure to 1800 MHz LTE electromagnetic fields under proinflammatory conditions decreases the response strength and increases the acoustic threshold of auditory cortical neurons

Figure 4

Effects of LTE exposure on parameters quantified from cortical responses in the LPS-treated animals. (a) BF distributions of the cortical neurons for the LPS-treated animals exposed to LTE (in black) and Sham-exposed to LTE (in white). The two distributions did not differ. (b–f) Effects of LTE exposure on the parameters quantifying the spectro-temporal receptive fields (STRF). The response strength was significantly decreased (* p < 0.05, unpaired t test) both on the entire STRF (total response strength) and at the best frequency (b,c). The response duration, the response bandwidth and the bandwidth were unchanged (d–f). Both the strength and the temporal reliability of the responses to vocalizations were decreased (g,h). Spontaneous activity was not significantly decreased (i). (* p < 0.05, unpaired t-tests). (j,k) Effects of LTE exposure on the cortical thresholds. The average thresholds were significantly higher in LTE-exposed rats compared to Sham-exposed rats. This effect was more pronounced in the low and middle frequencies.
