What is the key to set normalfont to the theorem-note and its brackets and its punct?

enter image description here


\begin{defi}[Normalfont Here]

You didn't indicate which of ntheorem's pre-defined theorem styles you employ -- plain, break, change, break, margin, marginbreak, nonumberplain, nonumberbreak, empty, and emptybreak -- so I'll assume you're fine with using the default style, viz., plain.

If this assumption is appropriate, just add the following instructions to the preamble (after loading ntheorem, obviously):

  {\item[\hskip\labelsep \theorem@headerfont ##1\ ##2\theorem@separator]}%
  {\item[\hskip\labelsep \theorem@headerfont ##1\ ##2 \mdseries (##3)\theorem@separator]}

Just in case you're curious, the default for the fourth line in the preceding chunk is

  {\item[\hskip\labelsep \theorem@headerfont ##1\ ##2\ (##3)\theorem@separator]}

Thus, the only change consists of the insertion of \mdseries immediately before (##3).
