'he' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'gets on with neurology principally barrier broken' is the wordplay.
'with' means one lot of letters go next to another.
'principally' says to take the initial letters.
'broken' is an anagram indicator.
The first letter of 'neurology' is 'n'.
'gets'+'on'+'n'+'barrier'='getsonnbarrier'
'getsonnbarrier' with letters rearranged gives 'ROGER BANNISTER'.
