Which term describes the connections established between different brain regions?

The term that describes the connections established between different brain regions is "neural pathways." Neural pathways refer to the bundles of axons that transmit signals between different areas of the brain or between the brain and other parts of the nervous system. These pathways facilitate communication and information processing throughout the brain, allowing for complex behaviors, thoughts, and functions to occur.

Understanding neural pathways is essential because they illustrate how neurons communicate with one another over distances within the brain, linking various regions that contribute to various cognitive functions, motor skills, and sensory processing.

Other options, though related to neural processes, do not specifically refer to the connections between different brain regions. Neurotransmitter releases pertain to the chemical signals sent across synapses but do not highlight the broader connections between areas. Neuronal networks refer to the interconnected group of neurons that can function together but don’t specifically emphasize the pathways connecting separate brain regions. Synaptic terminals pertain to the ends of neurons where neurotransmitter release occurs, representing a microscopic part of the larger network of connections.
