Sexually dimorphic behaviors arise from a differentiated nervous system, influenced by sensory cues and hormones. Understanding the neural circuits and modular control is key to explaining these complex behaviors.
Area of Science:
- Neuroscience
- Behavioral Biology
- Genetics
Background:
- Sexually dimorphic behaviors, differences between sexes, stem from a differentiated nervous system.
- Sensory cues and sex hormones orchestrate these behaviors, including courtship and aggression.
Purpose of the Study:
- To summarize current understanding of neural circuit control of sexually dimorphic behaviors.
- To explore how modular genetic and neural control generate cohesive behavioral states.
Main Methods:
- Review of existing research on neural circuits.
- Analysis of molecular mechanisms and evolutionary constraints.
- Examination of sexually dimorphic neurons and their function.
Main Results:
- Sexually dimorphic behaviors are controlled by distinct genes and neurons in a modular fashion.
- The transformation of modular control into cohesive behavioral states remains poorly understood.
- Emergent themes in dimorphic behavior control may apply to other behaviors.
Conclusions:
- Modular genetic and neural control is a key theme in sexually dimorphic behaviors.
- Further research is needed to understand the integration of modular control into unified behaviors.
- Principles of dimorphic behavior control may offer broader insights into neural control mechanisms.

The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci.
