TLDR
Olfactory perceptual processing is bidirectional and covers a wide frequency range and gamma band power in olfactory regions is significantly reduced during stimulus presentation as compared with high values during preafferent expectation.
Abstract
Field potentials were recorded simultaneously from the olfactory bulb (OB), prepyriform cortex (PPC), entorhinal cortex (EC), and dentate gyrus (DG) of rats trained to respond to appetitively reinforced odors. Preafferent anticipatory events in the beta band (12-35 Hz) suggest transmission from EC to OB before the odorant stimulus. Gamma band (35-120 Hz) power in olfactory regions is significantly reduced during stimulus presentation as compared with high values during preafferent expectation. High coherence of OB and PPC gamma activity during the preodorant control period is interrupted before the stimulus and is followed by increased gamma coherence among OB, EC, and DG. These results suggest that olfactory perceptual processing is bidirectional and covers a wide frequency range.

Neurophysiological and Computational Principles of Cortical Rhythms in Cognition

TL;DR: A plethora of studies will be reviewed on the involvement of long-distance neuronal coherence in cognitive functions such as multisensory integration, working memory, and selective attention, and implications of abnormal neural synchronization are discussed as they relate to mental disorders like schizophrenia and autism.

The dynamics of embodiment: a field theory of infant perseverative reaching.

TL;DR: It is demonstrated that the A-not-B error and its previously puzzling contextual variations can be understood by the coupled dynamics of the ordinary processes of goal-directed actions: looking, planning, reaching, and remembering.

Parallel-distributed processing in olfactory cortex: new insights from morphological and physiological analysis of neuronal circuitry.

TL;DR: To increase the accessibility of findings for PC and to advertise its substantial potential as a model for experimental and modeling analysis of associative processes, parallels are described between PC and the hippocampal formation, inferotemporal visual cortex and prefrontal cortex.

Toward an interpretation of dynamic neural activity in terms of chaotic dynamical systems

TL;DR: Using the concepts of chaotic dynamical systems, an interpretation of dynamic neural activity found in cortical and subcortical areas is presented in this article, which is quite different from the conventional one, cast in terms of simple behavior on low-dimensional attractors.

Odor encoding as an active, dynamical process : Experiments, computation, and theory

TL;DR: It is argued that early olfactory relays are active and dynamical networks, whose actions change the format of odor-related information in very specific ways, so as to refine stimulus identification.
