Non-Stationarity in Multisensory Neurons in the Superior Colliculus

Frontiers in Psychology, 2011
The superior colliculus (SC) integrates information from multiple sensory modalities to facilitate the detection and localization of salient events. The efficacy of multisensory integration is traditionally measured by comparing the magnitude of the ...

Superior Colliculus: A Vision for Orienting [PDF]

Current Biology, 2018
The superior colliculus contains neurons sensitive to motion direction. New research shows that these neurons are anatomically clustered: those representing the region of visual space 'seen' by both eyes preferentially respond to nasal motion directions and others to opposite directions.

A Role for the Superior Colliculus in Decision Criteria [PDF]

SSRN Electronic Journal, 2018
Simple decisions arise from the evaluation of sensory evidence. But decisions are determined by more than just evidence. Individuals establish internal decision criteria that influence how they respond. Where or how decision criteria are established in the brain remains poorly understood. Here, we show that neuronal activity in the superior colliculus (

Impaired Auditory Temporal Selectivity in the Inferior Colliculus of Aged Mongolian Gerbils [PDF]

, 2011
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.

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 ...

Anatomical Studies on Conduction Pathways of Advcrsive Movement [PDF]

, 1957
1. The descending fi bers from the areas 8 and 6 aβ reaching the lateral and ventral nuclei of the homolateral thalamus are recognized. They are considered to be the conduction pathways of the adversive movements caused by the stimulations on the ...

Superior Colliculus and Visual Spatial Attention [PDF]

Annual Review of Neuroscience, 2013
The superior colliculus (SC) has long been known to be part of the network of brain areas involved in spatial attention, but recent findings have dramatically refined our understanding of its functional role. The SC both implements the motor consequences of attention and plays a crucial role in the process of target selection that precedes movement ...

Cross-Correlation in the Auditory Coincidence Detectors of Owls [PDF]

, 2008
Interaural time difference (ITD) plays a central role in many auditory functions, most importantly in sound localization. The classic model for how ITD is computed was put forth by Jeffress (1948). One of the predictions of the Jeffress model is that the

Prenatal VPA exposure and changes in sensory processing by the superior colliculus

Frontiers in Integrative Neuroscience, 2011
Disorders involving dysfunctional sensory processing are characterized by an inability to filter sensory information, particularly simultaneously arriving multimodal inputs. We examined the effects of prenatal exposure to valproic acid (VPA), a teratogen

Superior Colliculus Control of Vibrissa Movements [PDF]

Journal of Neurophysiology, 2008
This study tested the role of the superior colliculus in generating movements of the mystacial vibrissae—whisking. First, we compared the kinematics of whisking generated by the superior colliculus with those generated by the motor cortex. We found that in anesthetized rats, microstimulation of the colliculus evoked a sustained vibrissa protraction ...
