Examples of how your brain helps you move, see, and remember.

🧠 Quick Study Guide

• 🏃‍♀️ Movement: The motor cortex in your brain sends signals through your spinal cord to your muscles, allowing you to move.
• 👀 Vision: Light enters your eyes and is converted into electrical signals. These signals travel to the visual cortex in the occipital lobe, where your brain interprets what you see.
• 📝 Memory: The hippocampus is crucial for forming new memories. Different types of memories (sensory, short-term, long-term) are stored in various brain regions.
• 💡 Neurons: Brain cells called neurons communicate with each other through electrical and chemical signals, enabling all brain functions.
• ⚡ Synapses: The connections between neurons, called synapses, strengthen with repeated use, improving learning and memory.
• 🧬 Neurotransmitters: Chemicals like dopamine and serotonin transmit signals across synapses, influencing mood, movement, and cognition.
