[Retrograde degeneration of the pyramidal cells in the motor cortex of apes (Macaca fascicularis)].
In three adult macaques the retrograde degeneration of cell bodies in the motor cortex was investigated 6 months after unilateral pyramidal tract section. Large and small Betz cells of the fifth layer were identified microscopically and counted. The analysis of the data reveals that after pyramidotomy, (1) contrary to our expectations from the extent of the pyramidal lesions, a surprising percentage of undegenerated Betz cells remains in the contralateral motor cortex, (2) a greater percentage of small rather than large cell survives, and (3) the greatest loss of cells is in the foot region, the smallest in the face region. The results are discussed in relation to the role of pyramidal axon collaterals in the survival of cell bodies, and the distinction between pyramidal cells and pyramidal tract cells.
Neuroanatomical localization of the motor hand area with magnetic resonance imaging: the left hemisphere is larger in great apes.
Magnetic resonance images of the brain were obtained from 2 gorillas (Gorilla gorilla gorilla), 4 orangutans (Pongo pygmaeus), 14 chimpanzees (Pan troglodytes), and 4 bonobos (Pan paniscus). The region on the motor cortex of humans identified as responsible for motor skill of the hand (the "knob") was identified in this sample on consecutive 1-mm axial scans. The shape of the knob area was traced on each scan from both hemispheres, and the area from all scans was summed to calculate the knob volume. The width of the knob was also measured and correlated highly with knob volume. A significant population-level leftward asymmetry in the volume and width of the knob was revealed (p < .05). Species differences in knob asymmetry and overall volume were not significant, but the variability in overall volume between species was substantial. Selection for the evolution of a neuroanatomical representation of the hand in primates and an evolutionary trend toward population-level right handedness are discussed.

Sexual selection and the comparative anatomy of reproduction in monkeys, apes, and human beings.
Sexual selection has had profound effects at the copulatory and postcopulatory levels, upon the evolution of reproductive anatomy, physiology, and patterns of mating behavior. This review deals with the effects of sexual selection upon the evolution of relative testes sizes, sperm morphology, seminal vesicular function, penile morphology, and copulatory behavior in the Order Primates. The concept of cryptic female choice is also discussed, and its potential value in understanding how co-evolution of genital morphologies may have occurred in primates and inother animals.
