  • Abstract
  • Look Inside

Our working hypothesis about mechanisms underlying the delayed neuronal death is as follows;Glutamate released to synaptic clefts in normal neurotransmission opens receptor operated ion channel to the post-synaptic membrane. In case of ischemia, a large amount of glutamate is released and perturbs the ion channel, and the channel allows an excess amount of ions to move across the fenestrated membrane. If the ion pumps can counteract to this ionic deluge, the affected neurons can maintain the homeostasis. However, because the mitochondria can not increase the rat of ATP production above normal, the maintenance of homeostasis may occur compromising with the biosynthetic activities.
