THE REFLEX ARC 267 



axiation of the cortex as a whole is absent or practically 

 absent, although a very definite surface-interior pattern 

 does exist. The dominant region of the cortex may 

 therefore shift from moment to moment and is purely 

 physiological and transitory rather than morphologically 

 persistent. That there is anything essentially new in 

 these suggestions I should be the last to claim. They 

 are brought forward here merely as the final point in the 

 discussion of functional direction in relation to the physio- 

 logical gradients.
