متن کاملSpatial attention improves the quality of population codes in human visual cortex.
Selective attention enables sensory input from behaviorally relevant stimuli to be processed in greater detail, so that these stimuli can more accurately influence thoughts, actions, and future goals. Attention has been shown to modulate the spiking activity of single feature-selective neurons that encode basic stimulus properties (color, orientation, etc.). However, the combined output from ma...
متن کاملSpatial Tuning Shifts Increase the Discriminability and Fidelity of Population Codes in Visual Cortex.
Selective visual attention enables organisms to enhance the representation of behaviorally relevant stimuli by altering the encoding properties of single receptive fields (RFs). Yet we know little about how the attentional modulations of single RFs contribute to the encoding of an entire visual scene. Addressing this issue requires (1) measuring a group of RFs that tile a continuous portion of ...
متن کاملTop-down activation of shape-specific population codes in visual cortex during mental imagery.
Visual imagery is mediated via top-down activation of visual cortex. Similar to stimulus-driven perception, the neural configurations associated with visual imagery are differentiated according to content. For example, imagining faces or places differentially activates visual areas associated with perception of actual face or place stimuli. However, while top-down activation of topographically ...
متن کاملPrimed-burst potentiation in adult rat visual cortex in vitro
The effectiveness of θ pattern primed-bursts (PBs) on development of primed-burst (PB) potentiation was investigated in layer II/III of the adult rat visual cortex in vitro. Experiments were carried out in the visual cortical slices. Population excitatory post-synaptic potentials (pEPSPs) were evoked in layer II/III by stimulation of either white mater or layer IV. To induce long-term potenti...
