Action potentials
Heat information is conducted through neurones. Higher frequency action potentials are perceived in the brain as a hotter stimulus. So the heated rod would have sent higher-frequency action potentials than the cool rod would have.
Action potentials also known as spikes, differ from graded potentials in that they do not diminish in strength as they travel through the neuron.

action potentials are non-decremental and do not get weaker with distance.
The FREQUENCY of action potentials that are conducted into the central nervous system serves as the code for the strength of the stimulus. This frequency code is needed because the amplitude of action potentials is constatnt (all or none). Acting through changes in action potential frequency, tonic receptors thus provide information about the relative intensity of a stimulus.
