abstract = {Substance P (SP), which is part of the tachykinin family,
is an undecapeptide. The peptide and its receptors are
present throughout the brain, including structures, such as
the amygdala, hippocampus, and striatum, which have an
acknowledged role in learning and memory. Despite some
uncertainties regarding SP capability to cross the
blood-brain barrier, an overwhelming body of research,
including systemic intervention, knockout models, and
targeted intracerebral injections of SP or its antagonists,
strongly supports the involvement of SP in learning and
memory. In this review, we discuss an involvement of SP in
nonassociative (habituation and sensitization) and
associative learning, focusing on classical conditioning
(place preference conditioning and place aversion) and
operant conditioning (avoidance learning, conditioned lever
pressing, and maze learning), and extend into the
acquisition of more complex behaviors such as those involved
in the 5-choice serial reaction time task and in the
memories that underlie learned and hard-wired innate serial
behaviors. In classical conditioning, SP can act as an
unconditioned stimulus, although its role in the associative
process per se is unclear. In operant conditioning, evidence
suggests that SP interacts with other neuromodulators, in
particular, dopamine, acetylcholine, and opioids in reward
prediction to influence learning directly. A similar
mechanism has been suggested to underlie the involvement of
SP in the acquisition of behavioral sequences. Additional
research is required in several areas, particularly in the
fields of human psychopharmacology and computational
neuroscience. These endeavors are essential to strengthen
the specific role of SP in learning and memory, and for
formulating new hypotheses regarding the underlying
mechanisms of the effects of SP.},
