Scientific research in neurology
identifies its functioning ( identification of places of reasoning, language, voluntary motor coordination, body awareness and environment, message integration, hearing center, memory and emotions)( and therefore the cerebral parts participating in the consciousness ( identified
8) in the parietal lobe) thanks to the scans made on people in coma and those in state of awakening. Our nerve cells ( 100 billion neurons per brain) communicate with each other by electrical signals via synapses ( terminations).
The more frequent the nerve impulse, the more the neuron produces chemicals ( neurostransmitters). The emotional brain coexists with the rational brain ( prefrontal cortex) and is at the root of our thoughts, actions, desires, and motivations.
In philosophy, Enactivism is a philosophical concept of cognition focused on how living organisms and human minds interact with the environment. Maybe this theory can also explain the collective consciousness.
