Neural induction is the first step in the formation of the brain. It is a mechanism by which Hensen's node (organizer), instructs adjacent tissue to adopt a neural fate, i.e. to give rise to the nervous system. This video demonstrates an assay for neural induction in chick embryo.

Source: Yong P. Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN This experiment will use inductive coils to demonstrate the concept of inductor and inductance. Magnetic induction will be demonstrated using a rod magnet inserted into or extracted away from the core of a coil to induce a transient electromotive force (emf) voltage in the coil, measured by a voltmeter. This experiment will also demonstrate the mutual inductance between...

All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Environmental enrichment involves objects and practices that encourage natural behaviors, improve psychological well-being, and promote better welfare in laboratory rodents. Environmental enrichment should be tailored to the...

They are obligate parasites that have no metabolic capacity, and in order to replicate, rely on host metabolism to produce viral parts that self-assemble inside host cells. Viruses are ultramicroscopic—too small to be viewed with the light microscope, visible only with...

The cue can alter cellular signaling, which in turn influences gene expression. These changes can redirect development, physiology, behavior, or visible phenotype while leaving the organism’s underlying DNA sequence unchanged. This mechanism explains how the same biological system can respond differently under different conditions and provides a basis for studying environmentally responsive traits.
These cues can influence different aspects of an organism’s biology through changes in cellular signaling and gene expression. Depending on the condition, the resulting response may appear during development, in physiological function, in behavior, or in overall phenotype. Considering both the environmental cue and the affected biological level helps connect habitat conditions with organismal responses.
It provides a way to examine how an organism can express different traits in response to its surroundings. Because these responses can arise through altered cellular signaling and gene expression rather than a change in DNA sequence, the concept links environmental experience with phenotype. This connection is central to interpreting phenotypic plasticity in biological and ecological research.
The two concepts should not be treated as synonyms. Environmental induction focuses on responses to external conditions, while research on those responses can inform the study of adaptation and evolutionary science. Keeping this distinction clear allows scientists to examine whether a trait reflects an organism’s environmental experience, a broader evolutionary pattern, or the relationship between both perspectives.
Each field uses the process to address a different level of biological explanation. Developmental biology can focus on how conditions influence development; ecology can examine responses in relation to habitats and interactions between organisms and their environments; evolutionary science can consider what those responses reveal about adaptation. Together, these perspectives connect cellular changes with broader biological patterns.
An induced phenotype can indicate that external conditions are influencing development, physiology, behavior, or another trait through cellular signaling and gene expression. Interpreting that response can connect a characteristic with the environmental experience associated with it. This makes the process useful for studying how organisms respond to changing conditions and interact with their habitats.
Environmental experiences can influence traits across an individual’s lifetime, so researchers can examine responses as dynamic outcomes rather than fixed features alone. This perspective is relevant when conditions change over time and when development, physiology, behavior, or phenotype must be considered together. It also connects an organism’s history with its present interaction with the environment.
