What's the difference between callosity and callous?
Callosity
Definition:
(n.) A hard or thickened spot or protuberance; a hardening and thickening of the skin or bark of a part, eps. as a result of continued pressure or friction.
Example Sentences:

(18) The callosal neurons could be separated into two categories: "double callosal" neurons which project both axon collaterals to two cortical areas of the contralateral hemisphere, and "associational-callosal" neurons which send axon collaterals to both hemispheres.
(19) Results from HRP studies of callosal connections indicated that transplant efferents to the contralateral cortex are smaller in magnitude than their afferents.
