How celebrity status and gaze direction in ads drive visual attention to shape consumer decisions

Journal article Psychology & Marketing · April 2023 AbstractMarketers have long used celebrity endorsement to help viewers build strong brand‐product associations. Celebrity endorsements increase brand awareness and recall, but how celebrity endorsements shape the decision p ... Full text Cite

Functional Clusters of Neurons in Layer 6 of Macaque V1.

Journal article J Neurosci · March 18, 2020 Layer 6 appears to perform a very important role in the function of macaque primary visual cortex, V1, but not enough is understood about the functional characteristics of neurons in the layer 6 population. It is unclear to what extent the population is ho ... Full text Link to item Cite

Distribution and diversity of intrinsically photosensitive retinal ganglion cells in tree shrew.

Journal article J Comp Neurol · January 1, 2019 Intrinsically photosensitive retinal ganglion cells (ipRGCs) mediate the pupillary light reflex, circadian entrainment, and may contribute to luminance and color perception. The diversity of ipRGCs varies from rodents to primates, suggesting differences in ... Full text Open Access Link to item Cite

Practical methods for in vivo cortical physiology with 2-photon microscopy and bulk loading of fluorescent calcium indicator dyes

Journal article · January 1, 2015 In vivo 2-photon imaging of neurons that have been bulk-loaded with fl uorescent calcium indicator dyes is permitting many fundamental principles of neural circuit organization and development to be uncovered. In this article, we describe the materials and ... Full text Cite

Advances in color science: from retina to behavior.

Journal article J Neurosci · November 10, 2010 Color has become a premier model system for understanding how information is processed by neural circuits, and for investigating the relationships among genes, neural circuits, and perception. Both the physical stimulus for color and the perceptual output ... Full text Open Access Link to item Cite

The representation of S-cone signals in primary visual cortex.

Journal article J Neurosci · August 4, 2010 Recent studies of middle-wavelength-sensitive and long-wavelength-sensitive cone responses in primate primary visual cortex (V1) have challenged the view that color and form are represented by distinct neuronal populations. Individual V1 neurons exhibit ha ... Full text Link to item Cite

The orientation selectivity of color-responsive neurons in macaque V1.

Journal article J Neurosci · August 6, 2008 Form has a strong influence on color perception. We investigated the neural basis of the form-color link in macaque primary visual cortex (V1) by studying orientation selectivity of single V1 cells for pure color patterns. Neurons that responded to color w ... Full text Link to item Cite

Cone inputs in macaque primary visual cortex.

Journal article J Neurophysiol · June 2004 To understand the role of primary visual cortex (V1) in color vision, we measured directly the input from the 3 cone types in macaque V1 neurons. Cells were classified as luminance-preferring, color-luminance, or color-preferring from the ratio of the peak ... Full text Link to item Cite

The spatial transformation of color in the primary visual cortex of the macaque monkey.

Journal article Nat Neurosci · April 2001 Perceptually, color is used to discriminate objects by hue and to identify color boundaries. The primate retina and the lateral geniculate nucleus (LGN) have cell populations sensitive to color modulation, but the role of the primary visual cortex (V1) in ... Full text Link to item Cite

High-frequency steering maneuvers mediated by tactile cues: antennal wall-following in the cockroach.

Journal article J Exp Biol · March 1999 Cockroaches (Periplaneta americana) use their antennae to detect a wall and to maintain a constant distance from it as they walk or run along it. The faster they run, the closer they position themselves to the wall. They also use their antennae to detect a ... Full text Link to item Cite
