The signals are then processed, resulting in immediate behaviors or memories. For example,
stimuli (light intensity and color) are received by the eye;
stimuli (sound waves) are received by the hair cells of the inner ear; more
stimuli (pressure) are received by the skin; and
stimuli (foods) are received by the various taste buds.
These stimuli are converted into electrical signals by the respective sensory organs. The eye converts light into electrical signals that are sent to the brain, which then processes the signals and allows us to see and interpret the visual stimuli. Similarly, the inner ear converts sound waves into electrical signals that are interpreted by the brain as sound, enabling us to hear.
The skin detects pressure stimuli and sends electrical signals to the brain, which helps us perceive touch and pressure. Taste buds, located in different regions of the tongue, receive stimuli from various foods and convert them into electrical signals. These signals are then sent to the brain, which helps us perceive different tastes such as sweet, sour, bitter, and salty.
Upon receiving these electrical signals, the brain processes the information and generates immediate behaviors or memories. For instance, if you touch a hot surface, the electrical signals from your skin will be processed in the brain, signaling the reflex action of quickly removing your hand to avoid getting burned. Similarly, when you see a vivid sunset, the electrical signals from your eyes will be processed and stored as a memory, allowing you to recall and visualize that sunset in the future.
In summary, the various sensory organs receive different stimuli and convert them into electrical signals. These signals are then processed by the brain, leading to immediate behaviors or the formation of memories.
