Summary
Adults who stutter (AWS) show compromised temporal resolution in auditory processing, specifically in temporal modulation transfer function (TMTF). This may impact speech planning and rhythmic movement programming in individuals with stuttering.
Area of Science:
- Neuroscience
- Speech-Language Pathology
- Auditory Perception
Background:
- Speech production and perception are increasingly linked in recent models.
- Individuals who stutter (AWS) often exhibit sensorimotor timing deficits and auditory processing issues.
- Previous research on AWS primarily focused on temporal ordering, with limited investigation into temporal resolution.
Purpose of the Study:
- To investigate temporal resolution abilities in adults who stutter (AWS).
- To compare temporal resolution between AWS and adults who do not stutter (AWNS).
Main Methods:
- Recruited 16 AWS and 16 age/gender-matched AWNS.
- Assessed temporal resolution using the Gap Detection Test.
- Evaluated temporal resolution using the temporal modulation transfer function (TMTF).
Main Results:
- Significant differences in TMTF were observed between AWS and AWNS.
- No significant differences were found in gap detection thresholds between the groups.
Conclusions:
- Auditory sensory representations of temporal modulations appear compromised in AWS.
- This compromise may affect the programming of rhythmic movements essential for speech planning in AWS.

1.7K
Protons bonded to heteroatoms such as nitrogen and oxygen exhibit a range of chemical shift values. This is due to the varying degree of hydrogen bonding between the proton and the heteroatom in other molecules. The extent of hydrogen bonding affects the electron density around the proton, thereby giving different chemical shift values for the protons in the proton NMR spectrum.

00:52¹H NMR of Conformationally Flexible Molecules: Temporal Resolution
1.3K
At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

01:27Gap Junctions
9.4K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

01:11The Auditory Ossicles
3.1K
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...

01:15Auditory Pathway
7.2K
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.
