Live imaging is a powerful tool to study cellular behaviors in real time. Here, we describe a protocol for time-lapse video-microscopy of primary cerebral cortex cells that allows a detailed examination of the phases enacted during the lineage progression from primary neural stem cells to differentiated neurons and glia.

Cilia of olfactory sensory neurons contain proteins of the signal transduction cascade, but a detailed spatial analysis of their distribution is difficult in cryosections. We describe here an optimized approach for whole mount labeling and en face visualization of ciliary proteins.
FAQs
Olfactory bulb neurons send distributed projections through the lateral olfactory tract rather than delivering odor information through a single narrowly defined pathway. In the receiving cortical network, this distributed input transforms receptor activity into odor representations. That organization helps explain how patterns generated at the receptors can support identifiable smells and flexible behavioral responses.
Distributed input allows activity from olfactory bulb neurons to be integrated across regions of the primary olfactory cortex, including the piriform cortex and related areas. This arrangement links receptor activity with broader cortical processing instead of treating each receptor signal as an isolated message. The resulting representations provide a foundation for investigating sensory coding in biological neural circuits.
The network supports rapid integration of odor information with memory and emotion, allowing smells to acquire significance beyond simple detection. This relationship helps explain why odor processing can influence behavior and why odor-linked memories are an important research focus. Studying these connections reveals how sensory representations participate in emotionally relevant experiences and responses.
Researchers can use this system as a framework for examining how olfactory receptor activity becomes a cortical odor representation. They can also relate that representation to the organization of neural circuits and to behavioral outcomes associated with smell. Together, these perspectives connect sensory input, cortical processing, and the biological significance of odor perception.
Investigations of the primary olfactory cortex can clarify how animals identify odors and associate them with appropriate behaviors. The same framework is relevant to feeding and defensive responses, where odor information may guide biologically important actions. Linking cortical odor representations with these outcomes helps researchers interpret smell as part of an integrated behavioral system.
Because olfactory processing integrates rapidly with memory, the primary olfactory cortex offers a useful context for studying how particular smells become associated with past experiences. Research can consider both the cortical representation of an odor and its behavioral significance. This makes the network relevant to understanding how sensory information participates in forming odor-linked memories.
Research on the primary olfactory cortex can provide a framework for examining dysfunction associated with impaired smell. Comparing normal odor representation and processing with disrupted olfactory function may help connect changes in sensory coding to altered perception. This subject-specific context also supports broader investigation of how neural circuit organization relates to the biological experience of smell.
