| Research Abstract |
We investigated whether solid feeding or liquid feeding was associated with functional recovery from learning/memory dysfunction, induced by cerebral infarction, among infarct model rats. In solid feed group, short term memory was recovered, and then expression of neurotrophin and promotion of proliferation were detected in hippocampus of unaffected side. This study suggests that the mastication required by a solid diet could contribute to the rehabilitation of short term memory dysfunction.
