Distinguished Lecture Series 2012
Aniruddh D. Patel, Associate Professor
Dept. of Psychology, Tufts University
Talk: Musical training, speech processing, and neural plasticity: what are the principles?
Date: Thursday, October 4th, 2012
Time: 3:00 - 4:30pm
Location: Meltzer Auditorium, 3rd floor, MEEI
Musical training, speech processing, and neural plasticity:
what are the principles?
There are growing indications that musical training (e.g., learning to play a
musical instrument) enhances the auditory processing of speech. While
these findings have potentially important implications, there is a need for
experimental (vs. correlational) studies, and for specific hypotheses about
how and why such effects would occur. In this lecture I present the
“OPERA” hypothesis, which proposes that such effects occur when five
essential conditions are met. These are: (1) Overlap: there is anatomical
overlap in the brain networks that process an acoustic feature used in both
music and speech (e.g., waveform periodicity, amplitude envelope), (2)
Precision: music places higher demands on these shared networks than does
speech, in terms of the precision of processing, (3) Emotion: the musical
activities that engage this network elicit strong positive emotion, (4)
Repetition: the musical activities that engage this network are frequently
repeated, and (5) Attention: the musical activities that engage this network
are associated with focused attention. According to the OPERA hypothesis,
when these conditions are met neural plasticity drives the networks in
question to function with higher precision than needed for ordinary speech
communication. Yet since speech shares these networks with music, speech

8:05 PM: Dinner
All students supported by the SHBT training grant (both MIT HST and Harvard DMS) are required to attend.
The End-of-Summer Talks provide a unique opportunity for students to present their research to the SHBT community and receive constructive feedback.
We hope you will be able to join us!
Dr. Sridhar Kalluri, Starkey Hearing Research Center, Berkeley CA
Advances in individualizing hearing-aid interventions and
in improving hearing-aid benefit in real-world environments
Monday November 21, 1:30pm
MIT Allen Room 36-462
Dr. Kalluri is a graduate of the first class (entered 1992) of the SHBT program. His dissertation focused on computational modeling of auditory neurons. Following his graduation in 2000, he did a postdoctoral fellowship at the University of Maryland, where he worked on the neural coding and perception of pitch and harmonicity. He joined the Starkey Hearing Research Center in 2004, where he is now Manager of Hearing Science Research. His research interest is in understanding impairment of auditory function and in applying this understanding to the design of novel hearing-aid technologies. In recent years, he has conducted research on the interaction of hearing aids with cognition and with binaural and spatial hearing.
In his talk, Dr. Kalluri will first talk about research at Starkey in general and then specifically about his own research on hearing aids. He will then open a discussion about careers in the hearing aid industry.
