Summary
Maternal behaviors, crucial for offspring, are dynamically regulated by dopamine (DA). This study explores how DA influences appetitive and consummatory aspects of maternal care over time.
Area of Science:
- Neuroscience
- Behavioral Biology
- Reproductive Science
Background:
- Maternal behavior is vital for offspring survival and development.
- Behaviors vary in appetitive/consummatory and active/passive dimensions.
- Dopamine (DA) is a key neuromodulator influencing maternal care.
Purpose of the Study:
- To examine the temporal dynamics of dopamine's role in maternal behavior.
- To understand how appetitive and consummatory drives evolve during maternal care.
- To propose that maternal behaviors are dynamic sequences regulated by neural systems.
Main Methods:
- Analysis of existing literature on dopamine and maternal behavior.
- Conceptual framework integrating temporal dynamics and behavioral axes.
- Examination of neural circuit regulation and neuromodulatory systems.
Main Results:
- Dopamine's role in maternal behavior is complex and time-dependent.
- Appetitive and consummatory components of maternal behaviors are not discrete but evolve.
- Neural dynamics shift across different timescales during maternal care.
Conclusions:
- Maternal behaviors are not static but dynamic sequences.
- Dopamine regulation of maternal care is intricate and varies over time.
- Understanding these temporal dynamics is key to comprehending maternal motivation and neural control.

310
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
