This is less true than you might think. While the main neurotransmitters are the same serotonin conveys different signals in mammalian and insect brains. Additionally these chemical reactions are modulated by the cells and a long period wave like alpha is related to more macro scale connectivity. The fact that a similar macro pattern emerges is not guaranteed by the fact that a neuron is a neuron. As a metaphor water molecules are identical but a snowflake and a raindrop are totally different in their material properties.
