An Introduction to Developmental Genetics

2023
Development is the complex process through which a single-celled embryo transforms into a multicellular organism. Developmental processes are guided by information encoded in an organism's DNA, and geneticists are trying to understand how this information leads to a fully formed organism. This video reviews seminal research in the field of developmental biology, including the identification of specific genes that control various embryonic processes. An introduction to the major questions asked...

Developmental neuroscience is a field that explores how the nervous system is formed, from early embryonic stages through adulthood. Although it is known that neural progenitor cells follow predictable stages of proliferation, differentiation, migration, and maturation, the mechanisms controlling the progression through each stage are incompletely understood. Studying development is not only important for understanding how complex structures are assembled, but also for characterizing and...

The Precision of Visual Working Memory with Delayed Estimation

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human memory is limited. Throughout most of its history, experimental psychology has focused on investigating the discrete, quantitative limits of memory—how many individual pieces of information a person can remember. Recently, experimental psychologists have also become interested in more qualitative limits—how precisely is information stored? The concept of memory precision can be both intuitive and elusive at once. It is...

Molecular signals play a major role in the complex processes occurring during embryonic development. These signals regulate activities such as cell differentiation and migration, which contribute to the formation of specific cell types and structures. The use of molecular approaches allows researchers to investigate these physical and chemical mechanisms in detail. This video will review a brief history of the study of molecular events during development. Next, key questions asked by molecular...

Delay discounting refers to a decline in the value of a reward when it is delayed relative to when it is immediately available. We outline a computer-based delay discounting task that is easy to implement and allows for the quantification of the degree of delay discounting in human participants.
FAQs
Several biological and environmental pathways may affect the timing of skill acquisition. Altered brain development or neural connectivity can arise in association with genetic conditions, prenatal or perinatal injury, infection, nutritional deficiency, or other environmental influences. Neuroscience examines these possibilities to connect observed developmental patterns with potential changes in how the nervous system forms and functions.
The pattern across motor, language, cognitive, social, and adaptive domains helps characterize a child’s developmental profile. Difficulties may involve one domain or several, and that distinction can guide further assessment of possible underlying mechanisms. Comparing domain-specific findings also helps clinicians and researchers describe developmental trajectories more precisely rather than treating all delays as identical.
Distinguishing these possibilities requires more than a single observation. Developmental history, standardized evaluations, and continued monitoring can show whether skills emerge later but continue progressing or whether difficulties remain broad and persistent. This distinction matters because it helps determine whether a child needs ongoing evaluation for a broader neurodevelopmental disorder and how support should be adjusted over time.
Assessment commonly combines developmental history with standardized evaluations of relevant skill domains. Clinicians may then use neuroimaging, genetic testing, or metabolic testing when the findings warrant investigation of underlying mechanisms. Using multiple information sources provides a more complete profile than relying on one measure and supports efforts to distinguish developmental patterns with different clinical implications.
These investigations provide complementary information about possible biological contributors to developmental differences. Neuroimaging can be incorporated with developmental findings, while genetic or metabolic testing may help examine associated mechanisms. They do not replace developmental history or standardized evaluation; instead, their value comes from integrating test results with the child’s observed pattern and developmental trajectory.
Early identification is useful when it enables targeted support before developmental difficulties become more established. It also creates a basis for monitoring progress and revising support as the child’s trajectory becomes clearer. In neuroscience and clinical practice, this approach connects assessment with practical outcomes, including better-informed care planning and improved support for children and families.
