Control of echolocation pulses by neurons of the nucleus ambiguus in the rufous horseshoe bat, Rhinolophus rouxi [PDF]
, 1986 1. Horseradish peroxidase was applied by iontophoretic injections to physiologically identified regions of the laryngeal motor nucleus, the nucleus ambiguus in the CF/FM batRhinolophus rouxi. 2.

Frontiers in Neural Circuits, 2021 Dopamine (DA) modulates the activity of nuclei within the ascending and descending auditory pathway. Previous studies have identified neurons and fibers in the inferior colliculus (IC) which are positively labeled for tyrosine hydroxylase (TH), a key ...

Review: Do the Different Sensory Areas within the Cat Anterior Ectosylvian Sulcal Cortex Collectively Represent a Network Multisensory Hub? [PDF]
, 2018 Current theory supports that the numerous functional areas of the cerebral cortex are organized and function as a network. Using connectional databases and computational approaches, the cerebral network has been demonstrated to exhibit a hierarchical ...

bioRxiv, 2019 The superior colliculus (SC) mediates rapid orienting to visual stimuli across species. To determine the specific circuits within the SC that drive orienting and approach behavior toward appetitive stimuli, we explored the role of three genetically ...

Adaptation of Binaural Processing in the Adult Brainstem Induced by Ambient Noise [PDF]
, 2012 Interaural differences in stimulus intensity and timing are major cues for sound localization. In mammals, these cues are first processed in the lateral and medial superior olive by interaction of excitatory and inhibitory synaptic inputs from ipsi- and ...

Spatial frequency sensitivity in macaque midbrain
Nature Communications, 2018 In primates, the superior colliculus (SC) contributes to rapid visual exploration with saccades. Here the authors show that the superior colliculus preferentially represents low spatial frequencies, which are the most prevalent in natural scenes.

Genetically Defined Functional Modules for Spatial Orienting in the Mouse Superior Colliculus
Current Biology, 2019 Summary In order to explore and interact with their surroundings, animals need to orient toward specific positions in space. Throughout the animal kingdom, head movements represent a primary form of orienting behavior.

The functional role of GABA and glycine in monaural and binaural processing in the inferior colliculus of horseshoe bats [PDF]
, 1992 The functional role of GABA and glycine in monaural and binaural signal analysis was studied in single unit recordings from the central nucleus of the inferior colliculus (IC) of horseshoe bats (Rhinolophus rouxi) employing microiontophoresis of the ...

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 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 ...
