Sensory input refers to the information our bodies receive from the environment through our senses. These senses include sight, hearing, taste, smell, and touch. Each sense collects data that our brain processes to help us understand and interact with the world around us. The brain interprets this sensory input to create our perceptions and reactions. For example, when we see a colorful flower, our eyes send signals to the brain, which helps us recognize its beauty. This process is essential for learning, communication, and overall functioning in daily life.
