  • „Effect of neurofeedback and transcranial alternating current on frontoparietal superior alpha and working memory“ changed to „The effect of neurofeedback on neurological post-COVID syndrome“ (M. Orendacova)


  • „Improving working memory by electrical stimulation and cross-frequency coupling“ (W. Al Qasem)


  • „Theta-Gamma-Coupling as predictor of working memory performance in young and elderly healthy people“ (M. Abubaker)


  • „Enhancement ofstatic postural stability by parallel transcranial stimulation of the cerebellum and motor cortex“ (M. Mehraban) … it is about: Transcranial electrical stimulation of the cerebellum is a safe method of stimulating or inhibiting its activity in special conditions such as stroke. The cerebellum controls the balance and postural stability of the human body, so stimulating the cerebellum can lead to better postural stability and balance reactions.
