Information about pain and temperature is conducted by the ____________.

The spinothalamic tract is the correct answer because it is the neural pathway responsible for transmitting information about pain and temperature from the body to the brain. This tract carries sensory information related specifically to nociceptive (pain) and thermoreceptive (temperature) stimuli. The primary afferent neurons that detect these sensations enter the spinal cord and synapse in the dorsal horn, where they then decussate (cross over) to the opposite side and ascend through the spinothalamic tract to reach the thalamus. From there, the information is relayed to the sensory cortex for perception, allowing us to consciously experience pain and temperature.

In contrast, the spinocerebellar tract primarily conveys proprioceptive information to the cerebellum for coordination of movement, the corticospinal tract is involved mainly in voluntary motor control, and the dorsal column-medial lemniscus pathway transmits fine touch, vibration, and proprioceptive information. Each of these pathways has distinct roles, highlighting the specific function of the spinothalamic tract in processing pain and temperature sensations.
