Odors in olfactory bulb are defined by a short discrete temporal sequence: recognition by brute-force conversion to a spatial pattern (chunking) [article]

Honi Sanders, Brian Kolterman, Roman Shusterman, Dmitry Rinberg, Alexei A. Koulakov, John Lisman
2014 arXiv   pre-print
Mitral cells, the principal neurons in the olfactory bulb, respond to odorants by firing bursts of action potentials called sharp events.  ...  The fact that this sequence is relatively short suggests a new class of "brute force" solutions to the problem of odor recognition: cortex may contain a small number of modules, each forming a persistent  ...  Thus, odor representation by a discrete temporal sequence may be a general property of olfactory recognition.  ...

The Brain Binds Entities and Events by Multiregional Activation from Convergence Zones

Antonio R. Damasio
1989 Neural Computation  
The experience of reality, in both perception and recall, is spatially and temporally coherent and "in-register." Features are bound in entities, and entities are bound in events.  ...  The degree of neural parcellation is even greater when we consider that the perception of most entities and events also requires a motor interaction on the part of the perceiver (such as eye movements  ...  Acknowledgments Supported by NINCDS Grant PO1 NS19632.

The Contribution of Brainstem and Cerebellar Pathways to Auditory Recognition

Neil M. McLachlan, Sarah J. Wilson
2017 Frontiers in Psychology  
Since sound recognition processes involving the brainstem and cerebellum initiate early in auditory processing, learnt information stored in cerebellar memory templates could then support a range of auditory  ...  This review expands our understanding of auditory processing by incorporating cerebellar pathways into the anatomy and functions of the human auditory system.  ...  However, the CN does not include a network capable of storing temporal sequences and operates on spectral information only.  ...

Global timing: a conceptual framework to investigate the neural basis of rhythm perception in humans and non-human species

Eveline Geiser, Kerry M. M. Walker, Daniel Bendor
2014 Frontiers in Psychology  
To understand how the brain gives rise to our experience of music we must appreciate how acoustical temporal patterns are integrated over the range of several seconds in order to extract global timing.  ...  In music perception, global timing comprises three distinct but often interacting percepts: temporal grouping, beat, and tempo.  ...  Walker is funded by an Early Career Research Fellowship from the University of Oxford. Daniel Bendor is funded by the Capita Foundation.  ...
