Neural response dynamics of spiking and local field potential activity depend on CRT monitor refresh-rate in the tree shrew primary visual cortex

Veit, Julia ; Bhattacharyya, Anwesha ; Kretz, Robert ; Rainer, Gregor

In: Journal of Neurophysiology, 2011, vol. 106, p. 2303-2313

Neural response dynamics of spiking and local field potential activity depend on CRT monitor refresh rate in the tree shrew primary visual cortex. Entrainment of neural activity to luminance impulses during the refresh of cathode ray tube monitor displays has been observed in the primary visual cortex (V1) of humans and macaque monkeys. This entrainment is of interest because it tends to...

Neural response dynamics of spiking and local field potential activity depend on CRT monitor refresh rate in the tree shrew primary visual cortex

Entrainment of neural activity to luminance impulses during the refresh of cathode ray tube monitor displays has been observed in the primary visual cortex (V1) of humans and macaque monkeys. This entrainment is of interest because it tends to temporally align and thus synchronize neural responses at the millisecond timescale. Here we show that, in tree shrew V1, both spiking and local field...

Own-species bias in the representations of monkey and human face categories in the primate temporal lobe

Sigala, R. ; Logothetis, Nikos K. ; Rainer, Gregor

In: Journal of Neurophysiology, 2011, vol. 105, no. 6, p. 2740-2752

Face categorization is fundamental for social interactions of primates and is crucial for determining conspecific groups and mate choice. Current evidence suggests that faces are processed by a set of well-defined brain areas. What is the fine structure of this representation, and how is it affected by visual experience? Here, we investigated the neural representations of human and monkey face...
