Synapse Plasticity in Motor, Sensory, and Limbo-Prefrontal Cortex Areas as Measured by Degrading Axon Terminals in an Environment Model of Gerbils (Meriones unguiculatus)

Figure 2

Top panel. Degrading axon terminals as indicated by silver-stained granules (light intensities) after Gallyas et al. (1980) [32] throughout the cortical layers of motor (Fr1), secondary sensory (Oc2), and limbic areas (IC) of an enriched-reared gerbil (dark field at 200x magnification). Middle panel. For every picture of the Gallyas staining, the marked sections (one per layer) were amplified. Note the distinct distribution of silver-stained granules in the different layers and areas. Bottom panel. Congruent sections (Nissl stainings) of the respective cortical areas. Scale bar = 100  m.
