Summary
This review synthesizes knowledge on olfactory bulb development, from prenatal stages through adulthood. It covers cell type maturation, function, and interactions, identifying key research gaps.
Area of Science:
- Neuroscience
- Developmental Biology
- Olfactory System Research
Background:
- The mammalian main olfactory bulb is essential for smell processing and develops early, remaining functional throughout life.
- Adult neurogenesis continuously shapes the olfactory system, indicating ongoing maturation and change.
- Understanding olfactory bulb development is critical for comprehending sensory processing and neural plasticity.
Purpose of the Study:
- To synthesize current knowledge on mammalian olfactory bulb development across prenatal, postnatal, and adult stages.
- To focus on the maturation, morphology, functions, and interactions of glutamatergic and GABAergic cell types.
- To identify significant advances and critical knowledge gaps in olfactory bulb development research.
Main Methods:
- Comprehensive literature review of recent studies on olfactory bulb development.
- Synthesis of findings related to cellular and functional maturation.
- Analysis of neurogenesis's role in adult olfactory bulb plasticity.
Main Results:
- Detailed overview of olfactory bulb development from early formation to adult stages.
- Elucidation of the roles and interactions of key neuronal cell types (glutamatergic and GABAergic).
- Highlighting of significant progress in understanding olfactory system maturation and adult neurogenesis.
Conclusions:
- Significant advances have been made in understanding olfactory bulb development.
- Gaps remain in knowledge regarding cellular interactions, functional maturation, and adult plasticity.
- Further research is urgently needed to address these knowledge gaps in olfactory system development.

Olfaction
45.6K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

Physiology of Smell and Olfactory Pathway
9.9K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

Olfactory Receptors: Location and Structure
9.8K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Neurulation
43.0K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...
