You will be given a definition of a task first, then some input of the task.
Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

To determine whether repeated seizures contribute to hippocampal sclerosis, we investigated whether cell loss in the (para) hippocampal region was related to the severity of chronic seizure activity in a rat model for temporal lobe epilepsy (TLE).', 'Chronic epilepsy developed after status epilepticus (SE) that was electrically induced 3-5 months before. The presence of neuronal damage was assessed by using Fluoro-Jade and dUTP nick end-labeling (TUNEL) of brain sections counterstained with Nissl.', 'We found a negative correlation between the numbers of surviving hilar cells and the duration of the SE (r = -0.66; p < 0.01). In the chronic phase, we could discriminate between rats with occasional seizures (0.15 +/- 0.05 seizures per day) without progression and rats with progressive seizure activity (8.9 +/- 2.8 seizures/day). In both groups, the number of TUNEL-positive cells in parahippocampal regions was similar and higher than in controls. In the hippocampal formation, this was not significantly different from controls. Fluoro-Jade staining showed essentially the same pattern at 1 week and no positive neurons in chronic epileptic rats.
Output:
Is neuronal cell death in a rat model for mesial temporal lobe epilepsy induced by the initial status epilepticus and not by later repeated spontaneous seizures?
