Neuronal glutamate that is released into the synaptic space is normally removed from the synaptic space by adjacent glial cells, in which the glutamate is converted to the closely related glutamine, which can then readily diffuse back into the neuron. Neuronal glutamate that is released into the synaptic space is normally removed from the synaptic space by adjacent glial cells, in which the glutamate is converted to the closely related glutamine, which can then readily diffuse back into the neuron. Glutamine is converted back to glutamate in the neuron.fig 14. Diagram shows sequence of events occurring in cerebral ischemia leading to neuronal death. (Free radical formation and lipase activation are also related to the increased intracellular calcium, although the two processes are not directly connected to the increased calcium by arrows in this schematic.)‏ Leighton P.
