Explain how greater brain complexity can arise from groups of neurons working together than can occur if neurons only communicated in chains in which each neuron only communicated with one presynaptic and one postsynaptic neuron.
What will be an ideal response?
Groups of neurons working together as networks generate greater complexity because they can create patterns of activity such as bursts in which neurons are extremely active, and those bursts can occur for varying lengths of time. In addition, there can be varying time intervals between high-amplitude activity. These patterns do contain information, as demonstrated in the study of taste perception in rats that was conducted by Patricia Di Lorenzo and Gerald Hecht.
