| Outline of Final Research Achievements |
We have examined effects of general anesthetics on amygdala/hippocampal synaptic transmission in the absence and presence of schizophrenia. Schizophrenia model rats were produced with methylazoxymethanol acetate（MAM）administration. Stimulating electrodes were placed in radiatum stratum (Rad) to stimulate CA1, and in amygdala-hippocampal area (AH) to simulate amygdala inputs to hippocampus. Two sets of extracellular recording microelectrodes were positioned in cell bodies and dendrites of CA1 to record population spikes (PSs) and excitatory post-synaptic potentials (EPSPs), respectively.
The train induced disinhibition (TID) protocol demonstrated that GABA recruitments schizophrenia model rats were deteriorated, suggesting that schizophrenia can modify anesthetic actions. The modification might explain delirium, excitation, or unexpected unstableness during genenal anesthesia.
