Localized Glutamate Uncaging in CA1 Pyramidal Neurons in Brain Slices

EPSCs (Excitatory Post Synaptic Currents) obtained in whole-cell voltage clamp mode in response to focal uncaging of glutamate onto multiple locations (marked by red crosses) around a single dendritic branch of a CA1 pyramidal neuron. Neurons were loaded with bis-Fura-2 by intracellular injection in a brain slice. The release zone is highly localized as evident from the relationship between the signal amplitude and the distance of the uncaging spot from the dendrite. (Uncaging in seven spots between the arrow heads)
