Summary
Children with cochlear implants demonstrate similar mismatch negativity (MMN) auditory responses to hearing children. MMN presence did not correlate with language development, speech perception, or family involvement in rehabilitation.
Area of Science:
- Auditory Neuroscience
- Neurophysiology
- Pediatric Audiology
Background:
- Mismatch negativity (MMN) is an auditory evoked potential reflecting cortical sound processing.
- MMN can offer insights into auditory function in children using cochlear implants (CIs).
Purpose of the Study:
- To characterize MMN latency, amplitude, and area in children with CIs compared to hearing children.
- To investigate associations between MMN and language development, speech perception, and family involvement in CI users.
Main Methods:
- A descriptive, observational, cross-sectional study comparing children with CIs and hearing children.
- MMN evaluation using tone burst stimuli and speech/language assessments.
- Classification of family participation in the rehabilitation process.
Main Results:
- MMN occurrence was 53.3% in children with CIs versus 73.3% in the control group.
- MMN latency, amplitude, and area were similar between children with CIs and hearing children.
- No significant correlations were found between MMN occurrence and language, speech perception, or family involvement.
Conclusions:
- Children with CIs exhibit comparable MMN responses to their hearing peers.
- MMN characteristics in CI users did not correlate with auditory/language development or family engagement.

01:20Mismatch Repair
6.3K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Work is done on an object when energy is transferred to the object. In other words, work is done when a force acts on a body that undergoes a displacement from one position to another. By definition, the work done by a force is the integral of the force with respect to the displacement along its path. Forces can vary as a function of position, and displacements can occur along various paths between two points. The magnitude of a force multiplied by the cosine of the angle that the force makes...

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...
