Adult Neuroplasticity: More Than 40 Years of Research
Figure 2
Electron micrographs of pyramidal neuron nuclei in the hippocampus of control and stressed male tree shrews: (a), control CA1; (b), stress CA1; (c), control CA3; (d), stress CA3. Note the homogeneous nucleoplasma (NP) in the controls and the large number of heterochromatin clusters (arrow) in nuclei of CA3 pyramidal neurons in stressed animals. NL: nucleolus. Calibration bar: 2 μm.
