Today’s lecture was dedicated to the Synaptic Transmission. We were studying related terms and definitions (gap junction, neurotransmitters and their 3 types, absolute and relative refractory period, EPSP, IPSP, etc.), classifications and mechanisms and different methods of research (optogenetic, for instance). The difference between chemical and electrical transmission was explained (electrical synapses are bidirectional and they are faster). Then, since the majority of synapses are chemical the rest of the lecture we were studying them only.
