Chen, "Postnatal exposure to tones alters the tuning characteristics of inferior collicular
neurons in the rat," Brain Research, vol.
Progressive degeneration of retinal and superior collicular
functions in mice with sustained ocular hypertension.
Structural MPI findings in thiamine-deficient animals show similar patterns of brain changes, including hyperintense signals observed on T2-weighted images in thalamus, collicular
bodies (Dror et al.
Moreover, the recent research on ascending auditory system suggests that the collicular
projections influence the acoustic signal processing by modulating neural response [16,17].
The circulation of the cerebral peduncle is mainly supplied by perforating branches from the collicular
artery, posteromedial choroidal artery, and circumflex branches from the pi or p2 segment of PCA.
Mural type: has single or few feeders from collicular
or posterior choroidal arteries.
The presence of other infarction areas in the PCA territory (supplying the occipital and the mesial temporal lobe) or their branches (e.g., collicular
artery, posteromedial choroidal artery, penetrating midbrain arteries, etc.) could help to consider other mechanisms of stroke than lipohyalinosis or microatheroma.
This was attributed to low-level phenomenon of "directional plasticity," where on a given trial it is easier for activity in the superior collicular
neurons to reach a threshold to trigger a saccade in the same direction as the prior saccade.
