BACKGROUND Eye examination as one of the painful procedures for retinopathy of prematurity screening can cause some pain-related physiological and behavioral changes in preterm infants. Multisensory stimulation is an analgesic non-pharmacological method that has analgesic effects on infants during painful procedures. OBJECTIVES This study aimed to determine the effect of multisensory stimulat...

Zamanın değerlendirilmesi meselesi sonuçları itibariyle insan hayatında çok merkezî bir yer tutmaktadır. İslâm inancı açısından insana verilen en önemli nimetlerden biri de zamandır. İnsan, kendisine bu nimeti yerinde değerlendirip değerlendirmemesine göre ahirette hesaba çekilecektir. Bu sebeple sûfîler zamanın meselesine son derece önem vermişlerdir. Onların zaman tanziminde üzerinde durdukla...

Multisensory integration is essential for the expression of complex behaviors in humans and animals. However, few studies have investigated the neural sites where multisensory integration may occur. Therefore, we used electrophysiology and retrograde labeling to study a region of the rat parietotemporal cortex that responds uniquely to auditory and somatosensory multisensory stimulation. This m...

The intricate relationship between multisensory integration and attention has been extensively researched in the multisensory field; however, the necessity of attention for the binding of multisensory stimuli remains contested. In the current study, we investigated whether diverting attention from well-known multisensory tasks would disrupt integration and whether the complexity of the stimulus...

Sensorimotor co-ordination in mammals is achieved predominantly via the activity of the basal ganglia. To investigate the underlying multisensory information processing, we recorded the neuronal responses in the caudate nucleus (CN) and substantia nigra (SN) of anaesthetized cats to visual, auditory or somatosensory stimulation alone and also to their combinations, i.e. multisensory stimuli. Th...

The development of multisensory neurons and multisensory integration was examined in the deep layers of the superior colliculus of kittens ranging in age from 3 to 135 d postnatal (dpn). Despite the high proportion of multisensory neurons in adult animals, no such neurons were found during the first 10 d of postnatal life. Rather, all sensory-responsive neurons were unimodal. The first multisen...

BACKGROUND Studies have produced conflicting evidence regarding whether cognitive control deficits in patients with schizophrenia result from dysfunction within the cognitive control network (CCN; top-down) and/or unisensory cortex (bottom-up). AIMS To investigate CCN and sensory cortex involvement during multisensory cognitive control in patients with schizophrenia. METHOD Patients with sc...

Multisensory neurons in the deep superior colliculus (SC) show response enhancement to cross-modal stimuli that coincide in time and space. However, multisensory SC neurons respond to unimodal input as well. It is thus legitimate to ask why not all deep SC neurons are multisensory or, at least, develop multisensory behavior during an organism's maturation. The novel answer given here derives fr...

Emotion perception naturally entails multisensory integration. It is also assumed that multisensory emotion perception is characterized by enhanced activation of brain areas implied in multisensory integration, such as the superior temporal gyrus and sulcus (STG/STS). However, most previous studies have employed designs and stimuli that preclude other forms of multisensory interaction, such as ...
