there are extensive evidences that show axonal processes of the nervous system (peripheral and/or central) may be degenerated after nerve injuries. wallerian degeneration and chromatolysis are the most conspicuous phenomena that occur in response to injuries. in this research, the effects of post-operative time following sciatic nerve crush on the number of spinal motoneurons were investigated....

Background: Glutamate is essential to learning and memory as an excitatory neurotransmitter. This study evaluated the atrazine effect on the hippocampus and examined the mitigative role of avocado oil against the neuronal degeneration and behavioral deficits in Wistar rats. Methods: Fifty adult male Wistar rats were divided into four groups of ten. Group 1 (controls) received 0.5 ml distilled ...

Depending upon the stimulus, neuronal cell death can either be triggered from the cell body (soma) or the axon. We investigated the origin of the degeneration signal in amyloid β (Aβ) induced neuronal cell death in cultured in vitro hippocampal neurons. We discovered that Aβ1-42 toxicity-induced axon degeneration precedes cell death in hippocampal neurons. Overexpression of Bcl-xl inhibited bot...
