Whether the strength of these attentional influences is similarly dependent on other stimulus properties is unknown. Here we report the effect of spatial attention on responses in the medial-temporal area (MT) of macaque visual cortex to moving random dots pattern of various motion coherences, i.e. signal-to-noise ratios. Our data show that allocating spatial attention causes a gain change in MT neurons. The magnitude of this attentional modulation is independent of the attended stimulus’ motion coherence, creating a multiplicative scaling of the neuron’s coherence-response function. This is consistent with the characteristics of gain models of attentional modulation and suggests that attention strengthens the neuronal representation of behaviorally relevant visual stimuli relative to unattended stimuli, but without affecting their signal-to-noise ratios."],["dc.identifier.doi","10.1038/srep27666"],["dc.identifier.gro","3151574"],["dc.identifier.pmid","27283275"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13397"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8384"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","2045-2322"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Attention enhances stimulus representations in macaque visual cortex without affecting their signal-to-noise level"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

The power of high frequency (>30 Hz) oscillations in LFPs is locked to the phase of low frequency (<30 Hz) oscillations, an effect known as phase-amplitude coupling (PAC). While PAC has been observed in a variety of cortical regions and animal models, its functional role particularly in primate visual cortex is largely unknown. Here, we document PAC for LFPs recorded from extra-striate area MT of macaque monkeys, an area specialized for the processing of visual motion. We further show that directing spatial attention into the receptive field of MT neurons decreases the coupling between the low frequency phase and high frequency power of LFPs. This attentional suppression of PAC increases neuronal discriminability for attended visual stimuli. Therefore, we hypothesize that visual cortex uses PAC to regulate inter-neuronal correlations and thereby enhances the coding of relevant stimuli."],["dc.identifier.doi","10.3389/fncir.2015.00082"],["dc.identifier.gro","3151551"],["dc.identifier.pmid","26733820"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12795"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8360"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","1662-5110"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Attention Decreases Phase-Amplitude Coupling, Enhancing Stimulus Discriminability in Cortical Area MT"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Here we used power of LFP recorded from area MT of a macaque monkey to decode where the animal covertly attended. Support vector machines (SVM) were used to learn the pattern of power at different frequencies for attention to two possible positions. We found that LFP power at both low (<9 Hz) and high (31-120 Hz) frequencies contains sufficient information to decode the focus of attention. Highest decoding performance was found for gamma frequencies (31-120 Hz) and reached 82%. In contrast low frequencies (<9 Hz) could help the classifier reach a higher decoding performance with a smaller amount of training data. Consequently, we suggest that low frequency LFP can provide fast but coarse information regarding the focus of attention, while higher frequencies of the LFP deliver more accurate but less timely information about the focus of attention."],["dc.identifier.doi","10.1371/journal.pone.0100381"],["dc.identifier.pmid","24979704"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11607"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/58335"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.mesh","Algorithms"],["dc.subject.mesh","Animals"],["dc.subject.mesh","Attention"],["dc.subject.mesh","Brain-Computer Interfaces"],["dc.subject.mesh","Craniotomy"],["dc.subject.mesh","Electroencephalography"],["dc.subject.mesh","Evoked Potentials, Visual"],["dc.subject.mesh","Macaca mulatta"],["dc.subject.mesh","Male"],["dc.subject.mesh","Microelectrodes"],["dc.subject.mesh","Photic Stimulation"],["dc.subject.mesh","Visual Cortex"],["dc.title","Decoding of visual attention from LFP signals of macaque MT."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
