Olfaction

47.5K
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.
The olfactory receptors are embedded in the cilia of the...

Physiology of Smell and Olfactory Pathway

11.4K
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.

Olfactory Receptors: Location and Structure

10.7K
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...

Area of Science:

  • Therapeutic interventions
  • Adolescent psychology
  • Sensory integration therapy

Background:

  • Adolescents in a Paris day hospital participated in therapeutic groups.
  • Many participants had not previously learned to engage their sense of smell.

Purpose of the Study:

  • To introduce a novel therapeutic approach using perfume workshops.
  • To explore the impact of olfactory stimulation on adolescent patients' sensory experiences, memory, and self-expression.

Main Methods:

  • A perfume workshop was implemented as a therapeutic group activity.
  • The intervention focused on mobilizing the sense of smell as a primary sensory mediator.

Main Results:

  • Participants discovered new sensory experiences through smell.
  • The workshop facilitated connection to personal sensations and memories.
  • Olfactory engagement fostered imagination, self-expression, and improved self-confidence.

Conclusions:

  • Perfume workshops offer a unique therapeutic avenue for adolescents.
  • Mobilizing the sense of smell can aid in emotional processing and communication.
  • This intervention shows promise in enhancing self-esteem and confidence in young patients.
