Prenatal Music Exposure Induces Long-Term Neural Effects
2013
We investigated the neural correlates induced by prenatal exposure to melodies using brains' event-related potentials (ERPs). During the last trimester of pregnancy, the mothers in the learning group played the ‘Twinkle twinkle little star’ -melody 5 times per week. After birth and again at the age of 4 months, we played the infants a modified melody in which some of the notes were changed while ERPs to unchanged and changed notes were recorded. The ERPs were also recorded from a control group, who received no prenatal stimulation. Both at birth and at the age of 4 months, infants in the learning group had stronger ERPs to the unchanged notes than the control group. Furthermore, the ERP amp…
Prevalence of Hearing Impairment Among High-Risk Newborns in Ibadan, Nigeria
2018
The burden of severe hearing impairment is increasing with two-thirds of these hearing impaired people residing in developing countries. Newborn hearing screening helps to identify early, babies who need intervention in order to prevent future disability. Neither universal nor targeted hearing screening programme is available in Nigeria. Objectives: This study was carried out to assess the prevalence of hearing impairment among high-risk newborns in UCH and the associated risk factors. Materials and Methods: Two hundred one newborns in the neonatal unit of UCH with risk factors for hearing impairment had hearing screening done using automated auditory brainstem response (AABR) at 30, 45, an…
Essential of audiology: screening and postscreening
2014
Newborn hearing screening is a type of screening testfor the early detection of hearing loss. It can recognizewith good accuracy newborns affected by hearingimpairment allowing an early diagnosis and interventionand avoiding cognitive and linguistic deficits [1-6].The incidence of bilateral sensorineural hearing loss(SNHL) in Sicily is 2.35 cases per 1000 newborns; thisvalue increases to 2.95 if we consider also unilateral SNHL[2,3] and to 10 cases per 1000 births among infants at risk[7-9].A correct newborn hearing screening programme isbased on different protocols depending on the presence/absence of audiologic risk factors:† Newborns without risk factors: [1-3]Initial Hearing Screening (…
Sporta spēļu nacionālo čempionātu videotiešraižu pieprasījums un piedāvājums Latvijas interneta un televīzijas vidē
2015
Bakalaura darba ''Sporta spēļu nacionālo čempionātu videotiešraižu pieprasījums un piedāvājums Latvijas interneta un televīzijas vidē'' mērķis ir noskaidrot, cik liels ir mediju videotiešraižu piedāvājums un auditorijas pieprasījums pēc nacionālo sporta spēļu čempionātu translācijām, kā arī, kādi faktori ietekmē to, ka aizvien vairāk translāciju veido interneta tiešraižu kompānijas, bet tradicionālās televīzijas to dara retāk. Darba teorētiskā daļa ietver teoriju par pieprasījumu un piedāvājumu, televīzijas un jauno mediju ietekmi sporta dzīvē, kā arī auditorijas lomu sportā un mediju darbībā. Metodoloģija ietver ekspertu intervijas, sekundāro datu analīzi un dziļās intervijas ar sporta aud…
I know what i like when i see it:Likability is distinct from pleasantness since early stages of multimodal emotion evaluation
2021
Liking and pleasantness are common concepts in psychological emotion theories and in everyday language related to emotions. Despite obvious similarities between the terms, several empirical and theoretical notions support the idea that pleasantness and liking are cognitively different phenomena, becoming most evident in the context of emotion regulation and art enjoyment. In this study it was investigated whether liking and pleasantness indicate behaviourally measurable differences, not only in the long timespan of emotion regulation, but already within the initial affective responses to visual and auditory stimuli. A cross-modal affective priming protocol was used to assess whether there i…
A wearable multimodal interface for exploring urban points of interest
2015
Locating points of interest (POIs) in cities is typically facilitated by visual aids such as paper maps, brochures, and mobile applications. However, these techniques require visual attention, which ideally should be on the surroundings. Non-visual techniques for navigating towards specific POIs typically lack support for free exploration of the city or more detailed guidance. To overcome these issues, we propose a multimodal, wearable system for alerting the user of nearby recommended POIs. The system, built around a tactile glove, provides audio-tactile cues when a new POI is in the vicinity, and more detailed information and guidance if the user expresses interest in this POI. We evaluat…
Context-dependent minimisation of prediction errors involves temporal-frontal activation
2020
According to the predictive coding model of perception, the brain constantly generates predictions of the upcoming sensory inputs. Perception is realised through a hierarchical generative model which aims at minimising the discrepancy between predictions and the incoming sensory inputs (i.e., prediction errors). Notably, prediction errors are weighted depending on precision of prior information. However, it remains unclear whether and how the brain monitors prior precision when minimising prediction errors in different contexts. The current study used magnetoencephalography (MEG) to address this question. We presented participants with repetition of two non-predicted probes embedded in cont…
Immuno-electron microscopic localization of the alpha(1) and beta(1)-subunits of soluble guanylyl cyclase in the guinea pig organ of corti.
2000
Guanylyl cyclases (GC) catalyze the formation of the intracellular signal molecule cyclic GMP from GTP. For some years it has been known that the heme-containing soluble guanylyl cyclase (sGC) is stimulated by NO and NO-containing compounds. The sGC enzyme consists of two subunits (alpha(1) and beta(1)). In the present study, the alpha(1) and beta(1)-subunits were identified in the guinea pig cochlea at the electron microscopic level using a post-embedding immuno-labeling procedure. Ultrathin sections of LR White embedded specimens were incubated with various concentrations of two rabbit polyclonal antibodies to the alpha(1)- and beta(1)-subunit, respectively. The immunoreactivity was visua…
Pure-Tone Thresholds, Speech Understanding, and Their Correlates in Samples of Men of Different Ages1
1986
Pure-tone thresholds and speech understanding were studied in three samples of men of different ages (31-35, 51-55 and 71-75 years). The air-conducted pure-tone thresholds were measured at 125-8,000 Hz and speech understanding by the help of interrupted and masked speech tests. The audiological measures were related to measures of other sensory functions, psychomotor speed, cognitive functions, psychic well-being, occupational and educational background and health. The results indicated a clear decrement in all audiological measures when proceeding from younger to older age groups. The results of the speech-understanding tests correlated significantly with the pure-tone thresholds both at 4…
Nordic Comparison of 75-Year-Olds - Sensory and Psychomotor Functions
1993
Sensory and psychomotor functions were studied among 75-year-old men and women in three Nordic localities (Glostrup in Denmark, Gothenburg in Sweden, and Jyvaskyla in Finland) as part of a comparative study on functional capacity and health. Random samples were drawn from the population registers in Glostrup (n=550) and Gothenburg (n=450), whereas in Jyvaskyla all 75-year-old residents (n=388) were invited to participate in the study. Participation rates varied from 66.8% in Gothenburg to 79.1% in Jyvaskyla. Sensory functions studied included hearing (pure-tone thresholds at 125-8000 Hz), vision (visual acuity, refraction, intraocular pressure), balance (postural sway), and tactual sensitiv…
