Question

the brains circuitry for smell also connects with areas involved in: memory storage. fear. visual input. auditory input.

Explanation:

The olfactory system (sense of smell) in the brain has connections with the limbic system. The limbic system is involved in memory (e.g., the hippocampus is part of the limbic system and crucial for memory formation and storage) and emotions (such as fear - the amygdala, which is part of the limbic system, plays a key role in processing fear). Visual input is mainly processed in the occipital lobe (visual cortex) and auditory input in the temporal lobe (auditory cortex), and these are not directly connected to the brain's smell - processing circuitry in the same way as memory and fear - related areas.

Answer:

memory storage, fear.
