Summary
Neurogenesis, the creation of new neurons, is crucial for brain development. Disruptions in this process within the olfactory system may contribute to neurodevelopmental disorders (NDDs) like ADHD and autism.
Area of Science:
- Neuroscience
- Developmental Biology
Background:
- Neurogenesis is vital for nervous system development.
- The mammalian olfactory system exhibits postnatal neurogenesis, making it a valuable model.
- Disruptions in neurogenesis are implicated in neurodevelopmental disorders (NDDs).
Purpose of the Study:
- To review the role of neurogenesis disruption in the olfactory system concerning NDDs.
- To explore how olfactory system neurogenesis alterations contribute to NDD pathophysiology.
Main Methods:
- Literature review of studies on neurogenesis and NDDs.
- Analysis of research utilizing human, mouse, and Drosophila models.
- Focus on the olfactory system as a model for NDD investigation.
Main Results:
- Summarizes current knowledge on olfactory neurogenesis disruptions in NDDs.
- Highlights the connection between distinct neurogenesis stages and NDDs.
- Identifies specific NDDs linked to olfactory system neurogenesis issues: ADHD, ASD, Down syndrome, Fragile X, and Rett syndrome.
Conclusions:
- The olfactory system serves as a powerful model for studying NDDs.
- Continued investigation using the olfactory system can advance understanding of NDDs.
- Disruptions in neurogenesis stages within the olfactory system are relevant to NDDs.

Olfactory Receptors: Location and Structure
9.2K
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...

Olfaction
44.3K
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
8.4K
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.

Neurogenesis and Regeneration of Nervous Tissue
772
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Attention-Deficit/Hyperactivity Disorder
59
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.
