Average 7T BOLD responses in the thalamus.
(A) Experimental design. Responses to monocular presentations of dynamic bandpass noise were recorded before and after 2 hr of monocular deprivation. Binocular rivalry was measured immediately …

Fourier analysis of BOLD responses.
(A) BOLD timecourses for each region of interest (ROI), averaged across conditions, subjects, and voxels. The gray line above the plot shows the stimulus contrast modulation (ON/OFF). (B) Fourier …

Alternative definition of thalamic regions of interest (ROIs).
(A) BOLD response evoked in a subset of participants (N = 9) with a visual-localizer experiment (binary noise, shown at the top). BOLD timecourses were averaged across participants after aligning to …

Short-term plasticity in ventral pulvinar, not in Lateral Geniculate Nucleus (LGN) or mid-dorsal pulvinar (dPulv).
(A, B, D) Modulation of visually evoked BOLD responses with monocular deprivation, in the deprived and nondeprived eye. BOLD responses were quantified by fast Fourier analysis of the functional …

Alternative region of interest (ROI) definition confirms short-term plasticity in pulvinar, not in Lateral Geniculate Nucleus (LGN).
Modulation of BOLD responses with monocular deprivation in anatomically defined ROIs (Bürgel et al., 2006; Bürgel et al., 1999; Najdenovska et al., 2018) intersected with functional activations (Figu…

Monocular deprivation does not affect either parvocellular or magnocellular Lateral Geniculate Nucleus (LGN) divisions.
(A) Coronal slice of the high-resolution 0.4 mm3 anatomy downloaded from a public repository (https://osf.io/xkqb3/; Amunts et al., 2013; Xiao et al., 2019); the hippocampus is evident on the lower …
