Autism Spectrum Disorder01:19

Autism Spectrum Disorder

1.2K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

IR Spectrum Peak Intensity: Amount of IR-Active Bonds

1.1K
When infrared radiation is passed through a molecule, absorption occurs if the molecule's vibration leads to a substantial change in its bond dipole moment. Transitions between vibrational energy levels, typically corresponding to infrared frequencies (4000–400 cm−1), allow absorption if the vibration significantly alters the dipole moment, making the molecule infrared active. The molecular bonds have different stretching and bending vibrations, resulting in various peaks with...

Decreasing Function01:27

Decreasing Function

299
A decreasing function describes a relationship where the output consistently declines as the input increases. This means that for any two input values, if one is greater than the other, the corresponding output is smaller. Mathematically, a function f is decreasing on an interval I if for every x1 < x2​ in I, f (x1) > f (x2). This type of behavior is visually identified on a graph that slopes downward from left to right.The nature of a function can be analyzed by calculating...

The Electromagnetic Spectrum02:37

The Electromagnetic Spectrum

65.3K
The electromagnetic spectrum consists of all the types of electromagnetic radiation arranged according to their frequency and wavelength. Each of the various colors of visible light has specific frequencies and wavelengths associated with them, and you can see that visible light makes up only a small portion of the electromagnetic spectrum. Because the technologies developed to work in various parts of the electromagnetic spectrum are different, for reasons of convenience and historical...

Subliminal Perception01:15

Subliminal Perception

794
Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Factors Affecting Perception01:25

Factors Affecting Perception

2.7K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Summary

Autism Spectrum Disorder (ASD) patients show impaired odor detection and identification. Neuroimaging reveals reduced olfactory bulb volume and piriform cortex activity, indicating olfactory changes are rooted in the primary olfactory cortex.

Area of Science:

  • Neuroscience
  • Sensory Processing
  • Autism Spectrum Disorder Research

Background:

  • Autism Spectrum Disorders (ASDs) involve atypical sensory processing across multiple modalities.
  • Olfactory dysfunction is reported in ASD but less understood compared to other sensory changes.
  • Neural underpinnings of olfactory alterations in ASD require further investigation.

Purpose of the Study:

  • To investigate olfactory function and neural correlates in adults with ASD.
  • To compare odor threshold and identification performance between ASD patients and neurotypical controls.
  • To examine structural and functional brain changes in the olfactory system of individuals with ASD.

Main Methods:

  • A two-phase study involving 18 adults with ASD and 18 healthy controls.
  • Assessment of odor threshold and odor identification capabilities.
  • Acquisition of structural MRI for olfactory bulb analysis and fMRI for olfactory processing in the piriform cortex.

Main Results:

  • ASD participants demonstrated significantly reduced performance in odor threshold and identification tasks.
  • Structural MRI indicated relatively decreased olfactory bulb volume in ASD patients.
  • Functional MRI revealed decreased activation in the piriform cortex during olfactory stimulation in the ASD group.

Conclusions:

  • Olfactory deficits in ASD are associated with measurable changes in the olfactory bulb and primary olfactory cortex.
  • Findings suggest that alterations in olfaction in ASD are rooted in the central olfactory processing areas.
  • This study provides neural evidence for olfactory system dysfunction in Autism Spectrum Disorder.
