abstract = {The N-methyl-D-aspartate receptor (NMDAR) is critical for
learning-related synaptic plasticity in amygdala and
hippocampus. As a consequence, there is considerable
interest in drugs targeting this receptor to help enhance
amygdala- and hippocampus-dependent learning. A promising
candidate in this respect is the NMDAR glycine-binding site
partial agonist D-cycloserine (DCS). Accumulating clinical
evidence indicates the efficacy of DCS in the facilitation
of amygdala-dependent fear extinction learning in patients
with phobic, social anxiety, panic, and obsessive-compulsive
disorder. An important unresolved question though is whether
the use of DCS can also facilitate hippocampus-dependent
declarative learning in healthy people as opposed to being
restricted to the fear memory domain.In the present study,
we investigated whether or not DCS can facilitate
hippocampus-dependent declarative learning. We have
therefore combined functional magnetic resonance imaging
with two different declarative learning tasks and
cytoarchitectonic probabilistic mapping of the hippocampus
and its major subdivisions in 40 healthy volunteers
administered either a 250 mg single oral dose of DCS or a
placebo.We found that DCS facilitates declarative learning
as well as blood-oxygen level dependent activity levels in
the probabilistically defined cornu ammonis region of the
hippocampus. The absence of activity changes in visual
control areas underscores the specific action of DCS in the
hippocampal cornu ammonis region.Our findings highlight
NMDAR glycine-binding site partial agonism as a promising
pharmacological mechanism for facilitating declarative
learning in healthy people.},
