Tufted cells are a type of neuron located in the olfactory bulb of the brain. They play a crucial role in the olfactory system by processing sensory information from the olfactory receptor neurons.

Structure[edit]

Tufted cells are characterized by their dendritic structure, which includes a primary dendrite that extends into the olfactory glomeruli. These cells receive direct input from olfactory receptor neurons and are involved in the initial stages of olfactory signal processing.

Function[edit]

Tufted cells are involved in the signal transduction process of the olfactory system. They receive input from olfactory receptor neurons and transmit this information to other parts of the olfactory bulb, such as the mitral cells. This process is essential for the perception of smell.

Types[edit]

There are different types of tufted cells, including external tufted cells and middle tufted cells. Each type has distinct properties and roles within the olfactory bulb.

Role in Olfactory Processing[edit]

Tufted cells contribute to the spatial and temporal coding of olfactory information. They help in refining the sensory input received from the olfactory epithelium and play a role in the lateral inhibition process, which enhances the contrast between different olfactory signals.

Clinical Significance[edit]

Understanding the function of tufted cells is important for research into olfactory disorders and neurodegenerative diseases that affect the olfactory system.

-Tufted cells are characterized by a single, thick [[axon]] that extends from the cell body into the deeper layers of the olfactory bulb. The dendrites of these cells form a tuft, or cluster, at the surface of the bulb, where they receive input from the olfactory receptor neurons. The dendrites of tufted cells are shorter and less branched than those of [[mitral cells]], another type of neuron in the olfactory bulb.

-Abnormalities in the structure or function of tufted cells can lead to disorders of the olfactory system, such as [[anosmia]] (loss of smell) or [[hyposmia]] (reduced ability to smell). Research is ongoing to better understand the role of tufted cells in these and other olfactory disorders.
