We describe the developmental changes of temporal, spectral and intensity characteristics of stridulation sounds, analyse the development of auditory sensitivity with growth, and examine whether S. schoutedeni is able to communicate acoustically throughout its life history.
Skeletons show evidence of auditory exostoses, a growth of cartilaginous tissue on ear bones that is found in humans who are repeatedly exposed to cold water – suggesting they frequently performed religious ceremonies in the river.
The impacts of underwater noise on fish are not well known, but limited research suggests that subjecting fish to noise could result in impairment of the auditory system, reduced growth rates, and increased stress.
Abnormal growth of auditory evoked responses recorded in central auditory nuclei accompanies the receptor damage during the sensitive period.
Rubel, E.W. & Fritzsch, B. Auditory system development: primary auditory neurons and their targets.
Adult sexually dimorphic traits such as second to fourth digit finger ratio [14], auditory system [15], craniofacial growth [16], visual acuity [17], canine size [18] and reproductive fitness [19] will be influenced by the gender of the developing neighbor.
More than 50% of pediatric cancer survivors will develop long-term complications, including cardiovascular, gonadal, and gastrointestinal/hepatic dysfunction, neurocognitive sequelae, auditory complications, and decline in growth, with approximately 25% of cases being severe [ 290].
The purpose of this study was to investigate fetal brain development of growth-restricted fetuses with auditory evoked responses (AER) that were recorded by the noninvasive magnetoencephalographic technique.
The presence of abnormal bone growths in the right auditory meatus (ear canal opening) caused a condition known as "surfer's ear" (auditory exostosis) and provides evidence that this individual most likely spent considerable time in the cold coastal waters sourcing food (Crowe et al. 2010).
Unilateral hearing loss may be a condition caused by a growth or tumor in the auditory pathway.
The team, led by Marcelo Rivolta, took human embryonic stem cells, which can grow into many different tissue types, and transformed them with chemical growth factors into both early stage auditory neurons and sensory hair cells found in the cochlea – the spiral tube that forms part of the inner ear.
