Key Insights
The nervous system is more than just the brain; it includes the spinal cord, connections between brain and body, and connections between organs. It’s a continuous loop of communication.
Nervous system functions are not just about sensation but include memory, movement, behavior, and decision-making.
Neurons are the building blocks of the nervous system. They transmit electrical signals via synapses, where chemicals are released to pass signals between neurons.
Memories are patterns of electrical activity in neurons, not stored as sentences or images.
Insights into the nervous system have come from various sources, including wartime injuries that revealed specific brain functions.
Sensation is a fundamental aspect of the nervous system, allowing us to perceive colors, touch, sound, and more.
Different species perceive the world differently based on their sensory receptors, offering unique perspectives on reality.
