“…Theoretically, a possible widespread axonal and trans-synaptic spreading of the TeNT within central neurons to many different brain regions may induce elevated excitability or pro-epileptogenic/pro-seizure state. Since rodents are naturally highly sensitive to loud sounds, we examined their response to short and long-lasting audiostimuli by examining the startle response and its prepulse inhibition, as well as the possible occurrence of audiogenic seizures [42,43]. However, elevated startle response or reduced prepulse inhibition, or the occurrence of audiogenic seizures, were not observed in the experiment (Figure 5 A-D).…”

“…Um reflexo do sobressalto diminuído foi encontrado em ratos que apresentam crises epilépticas audiogênicas (Cunha et al, 2020) provavelmente por apresentarem um déficit motor. No entanto, diferente dos resultados apresentados, esses animais apresentaram uma maior sensibilidade no ensaio de inibição pelo pré-pulso.…”

“…No grupo-teste, exposto ao ruído, a marcação para c-Fos indicou um aumento na atividade de neurônios piramidais em CA1 e CA3. Nesse grupo também observou-se: inibição no LTP como fora descrito por outros trabalhos(CUNHA et al, 2015(CUNHA et al, , 2018(CUNHA et al, , 2019DE DEUS et al, 2017) e redução na quantidade de BDNF no hipocampo. Sabe-se que um dos efeitos do BDNF é facilitar a indução do Fosfatidil Inositol -3-kinase (PI3-K).…”
