A 65-year old Parkinson's patient was being treated with electrical currents flowing to her brain. By mistake, the electrical current had flowed into one of the brain stem nuclei which produced the sudden emotional display of sadness. After this observable sad behaviour, the patient started to have feelings of sadness. Then, after reporting that she felt sad, she began having sad thoughts. After they stopped the brain stimulation, the emotion and feeling of sadness disappeared.
This case is important to note because there was a clear sequence of events: first, there was the emotion of sadness, followed by the feeling of sadness, followed by thoughts of sadness. Usually, all of these phenomena occur in a manner that is difficult to sequence because they are all conflated. Damasio also claims that thoughts of sadness occur because of the emotion and feeling of sadness that are linked to thoughts in a two-way network through associative learning. Thoughts may evoke emotions/feelings and emotions/feelings may evoke thoughts.
