Why Visual Function Does Not Correlate With Optic Glioma Size or Growth

Platelet size does not correlate with platelet age.

The relationship between platelet size and in vivo aging was investigated in the baboon using size-dependent platelet subpopulations separated by counterflow centrifugation. The separation characteristics, size, lactate dehydrogenase (LDH) activity, and dense-body content of the baboon platelet subpopulations were similar to those previously observed in studies of human platelets. Three indepen...

Why Does Similarity Correlate With Inductive Strength?

It has been repeatedly demonstrated that a robust predictor of the strength of an inductive argument is the similarity between the categories that are the focus of the induction. In this paper we evaluate why similarity is associated with the strength of such arguments. On one view, category similarity makes an argument strong because similarity is partially determined by features that are comm...

Why does the central nervous system not regenerate after injury?

A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...
