1. Binocular neurons in parastriate cortex: interocular 'matching' of receptive field properties, eye dominance and strength of silent suppression.

    PLoS ONE 9(6):e99600 (2014) PMID 24927276 PMCID PMC4057260

    Spike-responses of single binocular neurons were recorded from a distinct part of primary visual cortex, the parastriate cortex (cytoarchitectonic area 18) of anaesthetized and immobilized domestic cats. Functional identification of neurons was based on the ratios of phase-variant (F1) component...

  3. Tracking blue cone signals in the primate brain.

    The Australian Journal of Optometry 96(3):259 (2013) PMID 23186138

    In this paper, we review the path taken by signals originating from the short wavelength sensitive cones (S-cones) in Old World and New World primates. Two types of retinal ganglion cells (RGCs) carrying S-cone signals (blue-On and blue-Off cells) project to the dorsal lateral geniculate nucleus...

  5. Multiple pathways carry signals from short-wavelength-sensitive ('blue') cones to the middle temporal area of the macaque.

    Journal of Physiology 591(Pt 1):339 (2013) PMID 23070701 PMCID PMC3630789

    We recorded spike activity of single neurones in the middle temporal visual cortical area (MT or V5) of anaesthetised macaque monkeys. We used flashing, stationary spatially circumscribed, cone-isolating and luminance-modulated stimuli of uniform fields to assess the effects of signals originati...

  7. Phase sensitivities, excitatory summation fields, and silent suppressive receptive fields of single neurons in the parastriate cortex of the cat.

    Journal of Neurophysiology 106(4):1688 (2011) PMID 21715668

    We have recorded single-neuron activity from cytoarchitectonic area 18 of anesthetized (0.4-0.7% isoflurane in 65% N₂O-35% O₂ gaseous mixture) domestic cats. Neurons were identified as simple or complex on the basis of the ratios between the phase-variant (F1) component and the mean firing rate ...

  11. Influence of 'feedback' signals on spatial integration in receptive fields of cat area 17 neurons.

    Brain research 1328:34 (2010) PMID 20206150

    'Feedback' signals from mammalian extrastriate visual cortices are reported to exert primarily an excitatory influence on the classical receptive field (CRF) of neurons in the primary visual cortex (V1). However, given the much larger CRFs of neurons in extrastriate visual cortices it is not yet...

  15. Segregation of short-wavelength-sensitive (S) cone signals in the macaque dorsal lateral geniculate nucleus.

    European Journal of Neuroscience 30(8):1517 (2009) PMID 19821840 PMCID PMC2777259

    An important problem in the study of the mammalian visual system is whether functionally different retinal ganglion cell types are anatomically segregated further up along the central visual pathway. It was previously demonstrated that, in a New World diurnal monkey (marmoset), the neurones carr...

  17. Contrast dependence of center and surround integration in primary visual cortex of the cat.

    Journal of Vision 9(1):20.1 (2009) PMID 19271890

    The magnitudes of spike responses of area 17 (striate cortex, area V1) neurons to stimulation of their classical receptive fields were reduced (suppressed) when the stimuli extended into the silent surround regions. We found that when optimally oriented sine-wave drifting grating patches extende...

    Vision Research 48(26):2604 (2008) PMID 18397798

    We measured functional input from short-wavelength selective (S) cones to neurons in the dorsal lateral geniculate nucleus (LGN) and striate cortex (area V1) in anaesthetized marmosets. We found that most magnocellular (MC) and parvocellular (PC) cells receive very little (<5%) functional input ...
