Most fishes experiencing challenging environments are able to adjust and adapt their
physiology and behaviour to help them cope more effectively. Much of this flexibility is …

Larval zebrafish possess several experimental advantages for investigating the molecular
and neural bases of learning and memory. Despite this, neuroscientists have only recently …

Identifying molecular specializations in cortical circuitry supporting complex behaviors, like
learned vocalizations, requires understanding of the neuroanatomical context from which …

Complex motor skills in vertebrates require specialized upper motor neurons with precise
action potential (AP) firing. To examine how diverse populations of upper motor neurons …

The communication behaviors of vocal fish and electric fish are among the vertebrate social
behaviors best understood at the level of neural circuits. Both forms of signaling rely on …

Background The ability to imitate the vocalizations of other organisms, a trait known as vocal
learning, is shared by only a few organisms, including humans, where it subserves the …

Photoperiod and hormonal cues drive dramatic seasonal changes in structure and function
of the avian song control system. Little is known, however, about the patterns of gene …

Differences in central serotonergic function due to affective disorders and due to
extraordinary situations like suicidality may be visualized using the loudness dependence of …

In the face of changing behavioral situations, plasticity of sensory systems can be a valuable
mechanism to facilitate appropriate behavioral responses. In the auditory system, the …

Abstract Serotonin (5‐HT) is a modulator of neural circuitry underlying motor patterning,
homeostatic control, and social behavior. While previous studies have described 5‐HT …
