Across species, animals organize into social dominance hierarchies that serve to decrease
aggression and facilitate survival of the group. Neuroscientists have adopted several model …

Aggression is an adaptive behavior that plays an important role in gaining access to limited
resources. Aggression may occur uncoupled from reproduction, thus offering a valuable …

Steroids play a crucial role in modulating brain and behavior. While traditionally it is thought
that the brain is a target of sex steroids produced in endocrine glands (eg gonads), the brain …

Communication is inherently social, so signaling systems should evolve with social systems.
The 'social complexity hypothesis' posits that social complexity necessitates communicative …

Aggressive behaviors occurring dissociated from the breeding season encourage the
search of non-gonadal underlying regulatory mechanisms. Brain estrogen has been shown …

Social plasticity, defined as the ability to adaptively change the expression of social behavior
according to previous experience and to social context, is a key ecological performance trait …

Differences in social status are often mediated by agonistic encounters between
competitors. Robust literature has examined social status-dependent brain gene expression …

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 …

Aggressive behaviors are widespread among animals and are critical in the competition for
resources. The physiological mechanisms underlying aggression have mostly been …

For 100 years, the Journal of Comparative Physiology-A has significantly supported
research in the field of neuroethology. The celebration of the journal's centennial is a great …
