[HTML][HTML] Birds, primates, and spoken language origins: behavioral phenotypes and neurobiological substrates

CI Petkov, ED Jarvis - Frontiers in evolutionary neuroscience, 2012 - frontiersin.org
Vocal learners such as humans and songbirds can learn to produce elaborate patterns of
structurally organized vocalizations, whereas many other vertebrates such as non-human …

Attentional modulation of human auditory cortex

CI Petkov, X Kang, K Alho, O Bertrand, EW Yund… - Nature …, 2004 - nature.com
Attention powerfully influences auditory perception, but little is understood about the
mechanisms whereby attention sharpens responses to unattended sounds. We used high-…

[HTML][HTML] Conserved sequence processing in primate frontal cortex

B Wilson, WD Marslen-Wilson, CI Petkov - Trends in neurosciences, 2017 - cell.com
An important aspect of animal perception and cognition is learning to recognize relationships
between environmental events that predict others in time, a form of relational knowledge …

Multisensory interactions in primate auditory cortex: fMRI and electrophysiology

C Kayser, CI Petkov, NK Logothetis - Hearing research, 2009 - Elsevier
Recent studies suggest that multisensory integration does not only occur in higher association
cortices but also at early stages of auditory processing, possibly in primary or secondary …

Visual modulation of neurons in auditory cortex

C Kayser, CI Petkov, NK Logothetis - Cerebral Cortex, 2008 - academic.oup.com
Our brain integrates the information provided by the different sensory modalities into a
coherent percept, and recent studies suggest that this process is not restricted to higher …

[HTML][HTML] Integration of touch and sound in auditory cortex

C Kayser, CI Petkov, M Augath, NK Logothetis - Neuron, 2005 - cell.com
To form a coherent percept of the environment, our brain combines information from different
senses. Such multisensory integration occurs in higher association cortices; but supposedly…

[PDF][PDF] Mechanisms for allocating auditory attention: an auditory saliency map

C Kayser, CI Petkov, M Lippert, NK Logothetis - Current biology, 2005 - cell.com
Our nervous system is confronted with a barrage of sensory stimuli, but neural resources are
limited and not all stimuli can be processed to the same extent. Mechanisms exist to bias …

A voice region in the monkey brain

CI Petkov, C Kayser, T Steudel, K Whittingstall… - Nature …, 2008 - nature.com
For vocal animals, recognizing species-specific vocalizations is important for survival and
social interactions. In humans, a voice region has been identified that is sensitive to human …

[HTML][HTML] Functional imaging reveals numerous fields in the monkey auditory cortex

CI Petkov, C Kayser, M Augath, NK Logothetis - PLoS biology, 2006 - journals.plos.org
Anatomical studies propose that the primate auditory cortex contains more fields than have
actually been functionally confirmed or described. Spatially resolved functional magnetic …

Functional imaging reveals visual modulation of specific fields in auditory cortex

C Kayser, CI Petkov, M Augath… - Journal of …, 2007 - Soc Neuroscience
Merging the information from different senses is essential for successful interaction with real-life
situations. Indeed, sensory integration can reduce perceptual ambiguity, speed reactions…
