• Recordings using infrared-guided laser stimulation combined with whole cell recordings revealed a highly nonuniform distribution. Hot spots, with amplitude and integral of glutamate-evoked responses three times larger than responses evoked at neighboring sites, were detected. It appeared that the larger responses evoked resulted from an increase in activation of both AMPA and NMDA receptors. There was no correlation with branch points Show Other
