In an animal model of electrophysiological evaluation of cerebral ischemia-reperfusion, α-lipoic acid effect on the oxidative stress was studied by mean absolute amplitude of EEG spectra evaluation. The left carotideal infusion of 3.03 mM α-lipoic acid in Wistar rats after cerebral ischemia and reperfusion caused initial reduction and partial final recuperation of the various EEG spectral frequency mean absolute amplitudes (p<0.05). The left intracarotideal infusion of 6.06 mM α-lipoic acid significantly reverted the induced depression of mean absolute amplitude of theta and delta spectra. Nevertheless there was an increasing pattern of ischemia demonstrated by mean absolute amplitude depression of almost all EEG spectra with 60.6 mM α-lipoic acid infusion. These observations suggest that, depending on the administered concentration, α-lipoic acid may act in a dual way, protecting from ischemia at lower concentrations and worsening this process at higher doses.

Students were provided with the opportunity to directly compare a virtual and a live rat in a supplemental exercise for Learning courses. We argue that the design of teaching exercises should involve a systematic examination of student preferences between different available techniques. In general, students preferred a live rat over a virtual rat when learning concepts in operant conditioning, specifically a fixed-ratio schedule of reinforcement. Students also listed advantages and disadvantages of using a virtual rat versus a live rat. These aspects evaluated by students are compared and contrasted with those provided by experts who have reviewed these learning exercises.
