No binocular rivalry in the LGN of alert macaque monkeys
Orthogonal drifting gratings were presented binocularly to alert macaque monkeys in an attempt to find neural correlates of binocular rivalry. Gratings were centered over lateral geniculate nucleus (LGN) receptive fields and the corresponding points for the opposite eye. The only task of the monkey was to fixate. We found no difference between the responses of LGN neurons under rivalrous and no...
متن کاملDhruv, Et Al., Signal Summation in the Macaque Lgn
Title: Nonlinear signal summation in magnocellular neurons of the macaque lateral geniculate nucleus Abbreviated title: Signal summation in the macaque LGN Abstract Magnocellular (M-), but not parvocellular (P-) neurons of the macaque lateral geniculate nucleus (LGN) differ distinctively in their responses to counterphase-modulated and drifting gratings. Relative to stimulation with drifting gr...
متن کاملTemporal-chromatic interactions in LGN P-cells.
We studied the interaction between the chromatic and temporal properties of parvocellular (P) neurons in the lateral geniculate nucleus (LGN) of macaque monkeys. We measured the amplitudes and phases of responses to stimulation by spatially uniform fields modulated sinusoidally about a white point in a three-dimensional color space, at a range of temporal frequencies between 1 and 25 Hz. Below ...
متن کاملStriate cortex increases contrast gain of macaque LGN neurons.
Recurrent projections comprise a universal feature of cerebral organization. Here, we show that the corticofugal projections from the striate cortex (VI) to the lateral geniculate nucleus (LGN) robustly and multiplicatively enhance the responses of parvocellular neurons, stimulated by gratings restricted to the classical receptive field and modulated in luminance, by over two-fold in a contrast...
متن کاملVisual response latencies of magnocellular and parvocellular LGN neurons in macaque monkeys.
Signals relayed through the magnocellular layers of the LGN travel on axons with faster conduction speeds than those relayed through the parvocellular layers. As a result, magnocellular signals might reach cerebral cortex appreciably before parvocellular signals. The relative speed of these two channels cannot be accurately predicted based solely on axon conduction speeds, however. Other factor...
