Which neurotransmitter is often associated with the modulation of sensory information?

Serotonin plays a crucial role in modulating sensory information. It is involved in various functions within the central nervous system, including the regulation of mood, anxiety, and sensory perception. Serotonin helps fine-tune the processing of sensory input, influencing how we perceive and respond to different stimuli. Its presence can either enhance or inhibit sensory signal transmission, thereby shaping our experiences of the world around us.

Dopamine, while important in reward processing and motor control, is less directly involved in sensory modulation compared to serotonin. Acetylcholine is primarily associated with motor control and cognitive functions, and norepinephrine primarily impacts arousal and alertness levels but does not directly modulate sensory information to the same extent as serotonin does.
