- Analyzed dendritic branching in neurons from V1 - Cell Types: Stellate Cells - Cell body is small and circular - Sends axon branches locally only - Intracortical processing Pyramidal Cells - Cell body is large and triangular - Dendrites integrate information from local stellate cells - Sends axon branches both locally as well as to other areas of cortex/brain - Both intracortical processing and output to other areas Greenough et al., 1979, Continued
