Emotions: and memory: Your amygdala and hippocampus play important roles in storing memory, as well as associating certain memories with emotion.Language: Speaking and understanding language is a specialized brain function that involves several regions of your dominant hemisphere (the side of the brain opposite your dominant hand). The two major areas that control speech are Wernicke’s area, which controls the understanding of speech, and Broca’s area, which controls the fluency of your speech.The message is sent to your brainstem and then to your temporal cortex so that you can make sense of the sounds that you hear.
Hearing: You can detect sounds when a series of vibrations in your ear stimulate your vestibulocochlear nerve.The sensations of smell and taste often interact, as smell amplifies your experience of taste. These nerves send messages to your brain. Taste and smell: Your olfactory nerve detects smell, while several of your cranial nerves work together to detect taste.The occipital lobes put those messages together so that you can perceive what you are seeing in the world around you. Vision: Your optic nerves in your eyes can detect whatever you see, sending messages through your optic tract (pathway) to your occipital lobes.Each hemisphere receives sensory input from the opposite side of the body. This pathway is called the spinothalamic tract.
