How does the brain keep in touch with what is going on around us?

The brain keeps in touch with the surrounding environment through sensory organs that detect stimuli, such as sight, sound, touch, taste, and smell. These sensory inputs are transmitted to the brain via neurons, where they are processed and interpreted, allowing us to perceive and respond to our surroundings. Additionally, the brain continuously integrates information from various sensory modalities to create a coherent understanding of the environment, enabling us to make informed decisions and react appropriately. This complex interplay ensures that we remain aware and responsive to changes around us.
