Fig. 45 In this section the medial nucleus occupies the ventricular surface 
of the basal lobe of the great ventricular ridge. Ventrally this mass of cells 
merges with the general pallium. The dense lamina in the medial wall be- 
longs wholly or in part to the hippocampal formation. The small ridge in the 
lower angle of the ventricle lodges part of the stria terminalis bundle which 
spreads over the ventricular surface of the medial nucleus.
