Visual pattern discrimination in cats after removal of the superior colliculi [PDF]
Two groups of cats were trained to make a visual discrimination between two patterns in a standard discrimination apparatus. Animals in Group I were trained until they reached a criterion level of 90% correct responding, had bilateral lesions made in the superior colliculi (SC), and were retrained.

Superior colliculi and tracer dynamics of Patient A.
(A) Non-motion corrected image. (B) MAF corrected, (C) LORMC corrected PET images of Patient A, and (D) the corresponding MP-RAGE slice. The red arrows mark the superior colliculi. Uptake is visible only in the motion corrected PET images.

Did you choose appropriate tracer for retrograde tracing of retinal ganglion cells? The differences between cholera toxin subunit B and Fluorogold. [PDF]
Cholera toxin subunit B (CTB) and Fluorogold(FG) are two widely utilized retrograde tracers to assess the number and function of retinal ganglion cells (RGCs).

NMDA Currents Modulate the Synaptic Input–Output Functions of Neurons in the Dorsal Nucleus of the Lateral Lemniscus in Mongolian Gerbils [PDF]
Neurons in the dorsal nucleus of the lateral lemniscus (DNLL) receive excitatory and inhibitory inputs from the superior olivary complex (SOC) and convey GABAergic inhibition to the contralateral DNLL and the inferior colliculi.

Hydrocephalus caused by conditional ablation of the
To investigate the roles of Pten and β-Catenin in the midbrain, either the Pten gene or the β-catenin gene was conditionally ablated, using Dmbx1 (diencephalon/mesencephalon-expressed brain homeobox gene 1)-Cre mice.

Impaired Auditory Temporal Selectivity in the Inferior Colliculus of Aged Mongolian Gerbils [PDF]
Aged humans show severe difficulties in temporal auditory processing tasks (e.g., speech recognition in noise, low-frequency sound localization, gap detection). A degradation of auditory function with age is also evident in experimental animals.

Deficits in the activation of human oculomotor nuclei in chronic traumatic brain injury
Binocular eye movements form a finely-tuned system that requires accurate coordination of the oculomotor dynamics of the brainstem control nuclei when tracking the fine binocular disparities required for 3D vision.
