        orn envelopes littered the
        floor once again, as fourth-
        year students resumed the
decades-long tradition of cele-
brating their residency matches
in person.
     “We’ve had this pent-up
excitement over the last few years,
and the fact that we get to be
together in one space to share this
moment is magical,” said Ketan
Jain-Poster, who matched in oto-
laryngology at Kaiser Permanente
Oakland Medical Center.
     On Match Day, an annual
tradition held on the third Friday
of March, all fourth-year medical
students across the country learn
— at the exact same time — where
they will train as residents for the
next three to seven years.
     This year, Feinberg students
and their families attended the
Match Day celebration at the Louis
A. Simpson and Kimberly K. Querrey
Biomedical Research Center on
Northwestern’s Chicago campus.

crucial role in this process.
        For the current study, the investigators
studied dopamine activity in two regions of the
brain’s striatum, the dorsomedial striatum and
the dorsolateral striatum, which are involved in
different types of reward learning: the dorsome-
dial striatum is involved with goal-oriented learn-
ing behaviors, while the dorsolateral stratum is
involved with habitual behaviors.
        Although it was previously thought that habit
played a role in compulsion, to their surprise, the
team found that dopamine signaling activity was
actually upregulated in the mice’s dorsomedial
striatum, where it predicted the development of
compulsive reward-seeking behavior.
