A single hippocampal interneuron imaged by the Southampton Biosciences group.

Radiating out form the bright cell body in the middle of the picture, are dendrites, making up the radial receptive field of this interneuron. The punctate dots on the dendritic branches may be synaptic spines, but at this resolution it is difficult to tell. 

A diverse array of inhibitory interneurons exist in the hippocampus and you can read more here: on how this diversity emerges with development
