Abstract
Rhythmic sound or music is known to improve cognition in animals and humans We wanted to evaluate the effects of prenatal repetitive music stimulation on the remodelling of the auditory cortex and visual Wulst in chicks Fertilized eggs 0 day of white leghorn chicken Gallus domesticus during incubation were exposed either to music or no sound from embryonic day 10 until hatching Auditory and visual perceptual learning and synaptic plasticity as evident by synaptophysin and PSD95 expression were done at posthatch days PH 1 2 and 3 The number of responders was significantly higher in the music stimulated group as compared to controls at PH1 in both auditory and visual preference tests The stimulated chicks took significantly lesser time to enter and spent more time in the maternal area in both preference tests A significantly higher expression of synaptophysin and PSD95 was observed in the stimulated group in comparison to control at PH13 both in the auditory cortex and visual Wulst A significant interhemispheric and genderbased difference in expression was also found in all groups These results suggest facilitation of postnatal perceptual behaviour and synaptic plasticity in both auditory and visual systems following prenatal stimulation with complex rhythmic musicRoy S Nag TC Upadhyay AD Mathur R and Jain S 2014 Prenatal music stimulation facilitates the postnatal functional development of the auditory as well as visual system in chicks Gallus domesticus J Biosci 39 1–11 DOI 101007/s1203801394010
