Adaptive allocation of attentional gain.
21 Sep 2009 
Humans are adept at distinguishing between stimuli that are very similar, an ability that is particularly crucial when the outcome is of serious consequence (e.g., for a surgeon or air-traffic controller). Traditionally, selective attention was ...

Spatial organization of multisensory responses in temporal association cortex.
21 Sep 2009 Neurons in sensory cortices are often topographically organized according to their response preferences. We here show that such an organization of response preferences also exists in multisensory association cortex. Using electrophysiological ...

21 Sep 2009 Defensive behaviors, such as withdrawing your hand to avoid potentially harmful approaching objects, rely on rapid sensorimotor transformations between visual and motor coordinates. We examined the reference frame for coding visual information about ...

Transformation of polarized light information in the central complex of the locust.
21 Sep 2009 Many insects perceive the E-vector orientation of polarized skylight and use it for compass navigation. In locusts, polarized light is detected by photoreceptors of the dorsal rim area of the eye. Polarized light signals from both eyes are ...

"Black" responses dominate macaque primary visual cortex v1.
21 Sep 2009 Achromatic visual information is transferred from the retina to the brain through two parallel channels: ON-center cells carry "white" information and OFF-center cells "black" information (Nelson et al., 1978; Schiller, 1982; Schiller et al., 1986). ...

Multisensory congruency as a mechanism for attentional control over perceptual selection.
14 Sep 2009 The neural mechanisms underlying attentional selection of competing neural signals for awareness remains an unresolved issue. We studied attentional selection, using perceptually ambiguous stimuli in a novel multisensory paradigm that combined ...

Effect of acute antidepressant administration on negative affective bias in depressed patients.
13 Sep 2009 OBJECTIVE: Acute administration of an antidepressant increases positive affective processing in healthy volunteers, an effect that may be relevant to the therapeutic actions of these medications. The authors investigated whether this effect is ...

Evaluation of objective uncertainty in the visual system.
9 Sep 2009 The role of sensory systems is to provide an organism with information about its environment. Because sensory information is noisy and insufficient to uniquely determine the environment, natural perceptual systems have to cope with systematic ...

Predictable irregularities in retinal receptive fields.
8 Sep 2009 Understanding how the nervous system achieves reliable performance using unreliable components is important for many disciplines of science and engineering, in part because it can suggest ways to lower the energetic cost of computing. In vision, ...
