A Local field potentials (LFPs) from MEA recordings indicate the expression of Tat and Nef significantly suppressed neuronal activity, where black, blue, and red color indicate normal, suppressed, and silenced activities, respectively. AOX treatment of Tat expressing neurons was capable of inhibiting further attenuation in network firing frequencies and partially stabilizing amplitudes, while treatment in Nef expressing neurons only partially preserved firing amplitudes under acute conditions. B Raster plots demonstrated the highly synchronous and regular firing activity at baseline was fully mitigated by the expression of Tat or Nef. AOX treatment resulted in a partial restoration of synchronous activity in the Tat expressing group, but not Nef. C Analyses of correlation-based conduction velocities revealed the application of AOX prevented further attenuation in temporal firing dynamics in Tat expressing neurons, and improved activity in the Nef expressing group. *p < 0.05; **p < 0.01; ***p < 0.001.
