Superior sensation: superior colliculus participation in rat vibrissa system
BMC Neuroscience, 2007 Background The superior colliculus, usually considered a visuomotor structure, is anatomically positioned to perform sensorimotor transformations in other modalities.

Abstract Representation of Movement Parameters in Basal Ganglia Output
Advanced Science, EarlyView.The basal ganglia output provides a scalable velocity/position signal across behavioral contexts, supporting the idea that these variables are represented in the brain as abstract entities rather than as fixed changes in joint angles or specific sets of body effectors.

Cervical dystonia: a disorder of the midbrain network for covert attentional orienting.
Frontiers in Neurology, 2014 While the pathogenesis of cervical dystonia remains unknown, recent animal and clinical experimental studies have indicated its probable mechanisms. Abnormal temporal discrimination is a mediational endophenotype of cervical dystonia and informs new ...

A Molecularly Defined Midbrain Circuit Mechanism for Sound‐Driven Defensive Behavior and Anxiety
Advanced Science, EarlyView.Schematic diagram showing the Cbln2+ ICx–dPAG circuit for sound‐driven defensive and anxiety‐like behaviors. ABSTRACT The innate defense behaviors in response to threatening sounds play a fundamental role in survival. However, the neural circuits that detect threat‐relevant auditory cues and transform them into defensive behaviors remain poorly defined.

Exploring the Superior Colliculus In Vitro
Journal of Neurophysiology, 2009 The superior colliculus plays an important role in the translation of sensory signals that encode the location of objects in space into motor signals that encode vectors of the shifts in gaze direction called saccades. Since the late 1990s, our two laboratories have been applying whole cell patch-clamp techniques to in vitro slice preparations of ...

Production of 3D printed biomodels of the canine brain for veterinary neuroanatomy teaching
Anatomical Sciences Education, EarlyView.Abstract Teaching neuroanatomy presents multiple challenges to both students and teachers, as it is a subject with highly dense content that commonly causes the development of aversion by students, a phenomenon referred to as “neurophobia,” which has been documented in human and veterinary medicine students.

Cerebellar projections to the superior colliculus in the cat [PDF]
The Journal of Neuroscience, 1981 The projections from the cerebellar nuclei to the superior colliculus of the cat have been studied by injecting small amounts of horseradish peroxidase into the colliculus and charting the distribution of the labeled neurons in the cerebellar nuclei.

Warning! Dopaminergic Modulation of the Superior Colliculus [PDF]
Trends in Neurosciences, 2016 Recent work by Bolton et al. describes a dopaminergic input to the superior colliculus (SC) from the zona incerta, as well as the organization of D1- and D2-receptor expression in the SC. We discuss a potential role for this input in modulating SC-mediated behavior, particularly in response to aversive stimuli.

The tectonigral pathway regulates appetitive locomotion in predatory hunting in mice
Nature Communications, 2021 Goal-oriented movement is a fundamental animal behaviour. Here, the authors show that neurons in the superior colliculus project to the substantia nigra pars compacta, regulating dopaminergic signaling and specifically appetitive locomotion in mice.
