Mission: promoting scientific literacy, growing the neuroscience community, and developing effective science communicators.. WHY?. Science outreach is critical. WHY?. "So, when you guys do your research, you start with a scientific—what do they call it—postulate or theory, and you work from that direction forward, is that right. Like light, sound travels in waves and like vision, in order to hear, we first need to receive the sensory input of the waves and then convert them into neural impulses sent to, and processed by, the brain. into local. receptor . potentials.

Majorand MinorwwwNeurosciencePitteduRevised08/2019Neuroscience is the study of the biological bases and consequences of behavior with a special focus on the role of the nervous system in these process An integrated overview of hearing and the interplay of physical, biological, and psychological processes underlying it.Every time we listen--to speech, to music, to footsteps approaching or retreating--our auditory perception is the result of a long chain of diverse and intricate processes that unfold within the source of the sound itself, in the air, in our ears, and, most of all, in our brains. Hearing is an everyday miracle that, despite its staggering complexity, seems effortless. This book offers an integrated account of hearing in terms of the neural processes that take place in different parts of the auditory system.Because hearing results from the interplay of so many physical, biological, and psychological processes, the book pulls together the different aspects of hearing--including acoustics, the mathematics of signal processing, the physiology of the ear and central auditory pathways, psychoacoustics, speech, and music--into a coherent whole. Ear. The ear converts changes in pressure in the air to changes in the electrical activity of neurons. . The . human ear can detect sound frequencies between 20 and 20 000 Hz.. Anatomists distinguish the outer ear, the middle ear, and the inner ear. Alberto Masala (PI), SND, Univ. Paris Sorbonne. Daniel Andler, SND, Univ. Paris Sorbonne. Jean Denizeau, MBB, ICM, Univ.
