Summary
Children with functional articulation disorders (FAD) show prolonged central auditory processing, indicated by delayed mismatch negativity (MMN) responses. This suggests auditory processing deficits may contribute to speech sound disorder development.
Area of Science:
- Neuroscience
- Speech-Language Pathology
- Developmental Pediatrics
Context:
- Functional articulation disorders (FAD) are common speech sound disorders in children.
- Central auditory processing (CAP) refers to the efficiency of the auditory system in interpreting sound.
- Understanding the underlying mechanisms of FAD is crucial for effective intervention.
Purpose:
- To investigate central auditory processing function in children diagnosed with FAD.
- To explore potential causes of FAD by examining auditory event-related potentials.
- To compare CAP measures between children with FAD and typically developing peers.
Summary:
- A study compared 27 children with FAD to 50 controls using auditory event-related potentials, specifically mismatch negativity (MMN).
- Children with FAD exhibited a higher incidence of prior language development disorders (70% vs 8%).
- Significantly prolonged MMN peak latency was observed in the FAD group (209 ms vs 175 ms), suggesting delayed auditory signal processing.
Impact:
- Findings suggest that prolonged central auditory processing may be a contributing factor to the development of functional articulation disorders in children.
- This research highlights the importance of assessing auditory processing skills in children with speech sound disorders.
- Identifying CAP deficits can inform targeted therapeutic strategies for FAD.

01:28Integration of Synaptic Events
4.2K
Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability to...

01:28Articulations of the Vertebral Column
3.2K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

02:18Intrinsically Disordered Proteins
19.6K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

01:11The Auditory Ossicles
3.2K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

01:17Auditory Perception
1.1K
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

01:15Auditory Pathway
7.5K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
