This book summarizes the latest research findings in the neurocircuitry of innate behaviors, covering major topics such as
innate fear, aggression, feeding, reward, social interaction, parental care, spatial navigation, and sleep-wake regulation.
For decades, humans have been fascinated by wild animals' instincts, like the annual two-thousand-mile migration of the monarch
butterfly in North American, and the "imprint" behavior of newborn birds. Since these instincts are always displayed in stereotypical
patterns in most individuals of a given species, the neural circuits processing such behaviors must be genetically hard-wired
in the brain. Recently, with the development of modern techniques, including optogenetics, retrograde and anterograde virus
tracing, and in vivo calcium imaging, researchers have been able to determine and dissect the specific neural circuits for
many innate behaviors by selectively manipulating well-defined cell types in the brain. This book discusses recent advances
in the investigation of the neural-circuit mechanisms underlying innate behaviors.
