Answer:
Cerebellum
Explanation:
In addition to coordinating movement, the cerebellum participates in
motor learning, emotional behavior, and fear memory. Fear learning
is reflected in a change of autonomic and somatic responses, such
as heart rate and freezing, elicited by a neutral stimulus that has been
previously paired with a
painful one. Manipulation of
the vermis affects these
responses, and its reversible
inactivation during the
consolidation period impairs
fear memory. The neural
correlate of cerebellar
involvement in fear
consolidation is provided by a
behaviorally induced long-
term increase of synaptic
efficacy between parallel fibers
and a Purkinje cell. Similar
synaptic changes after fear
conditioning are well
documented in the amygdala
and hippocampus, providing a
link between emotional
experiences and changes in
neural activity. In addition, in
hotfoot mice, with a primary
deficiency of parallel fiber to
Purkinje cell synapse, short-
and long-term fear memories
are affected. All these data
support the idea that the
cerebellum participates in fear
learning. The functional
interconnection of the vermis
with hypothalamus, amygdala,
and hippocampus suggests a
more complex role of the
cerebellum as part of an
integrated network regulating
emotional behavior.
