To elucidate the neural basis for interactions between the auditory and motor systems in the context of musical rhythm perception and production
To examine the neural basis of beat percepti
on
To investigate proposal: Neural resonance provides an excellent account of many aspects of rhythm perc
eption
To investigate how top

control of rhythm perception modulates early auditory responses
1) I
sochronous rhythm,
progressively altered metric saliency 2
-3) Three rhythms
differing in com
plexity: simple,
complex, ambiguous (nonmetric)
(
SNI
)
CR: Neutral 1) Novel rhythmic
sequences,
3 sec: metric simple, metric complex, nonmetric.
2) Beat and nonbeat versions of sequences, 1
1-18 sec:
Volume accented, dura

accented, unaccented
(SNI)
CR: Neutral No particular musical material, multiple
references
CR:
---
A repeating sequence of two tones followed by a rest. 45 msec duration
pure tones:
1 kHz pips, inter-
onset
intervals 200 msec
CR: Neutral
fMRI: Tasks: 1) tapping to rhythm
. 2) a) listening b)
tapping to rhythm
.
3) a) listening b)
listening with
anticipation to tap c) tapping to rhythm

Review of literature, especially EEG and MEG studies. Proposal of a theoretical framework
1) ”i
magined beat” condi
tion.
Instruction: mentally place the beat a) on 1st tone b) on 2nd tone 2) ”physical accent” condition. One to
ne is
accented, a) 1st tone
b) 2nd tone
To investigate different couplings bet
ween
the
auditory and motor systems
Functional connectivity between
part of the basal
ganglia (putamen) and cortical areas: premotor and supplementary motor areas
Neural correlates of rhythm perception in high
-frequency
oscillatory activity
MEG: 1) To test whether voluntary metrical interpretation modulates brain res
ponses
2) To test the contribution af exogenous factors in shaping brain responses
Dorsal premotor cortex
(PMC)
is sensitive to
rhythm’s metric structure. Ventral PMC is not, but it is sensitive to process
ing
action-
related sounds. The
mid
-PMC is engaged during
both passive listening and tapping.
The basal ganglia is strongly implicated in processing
a regular beat,
especially when internal generation of the beat is required
Hypothesis: Perception of pulse and meter result from rhythmic bursts of high
frequency neural
activity in
response to
musical rhythms
1) Metrical interpretation influenc
ed early evoked
neural responses to tones, specifically in the upper beta range (20
-30 Hz)
2) This beta increase resembles that due to physical accents
