Review: Do the Different Sensory Areas within the Cat Anterior Ectosylvian Sulcal Cortex Collectively Represent a Network Multisensory Hub? [PDF]

open access: yes, 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 ...

Dopamine in Auditory Nuclei and Lemniscal Projections is Poised to Influence Acoustic Integration in the Inferior Colliculus

open access: yesFrontiers 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 ...

Control of echolocation pulses by neurons of the nucleus ambiguus in the rufous horseshoe bat, Rhinolophus rouxi [PDF]

open access: yes, 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.

Saccade learning with concurrent cortical and subcortical basal ganglia loops [PDF]

open access: yes, 2013
The Basal Ganglia is a central structure involved in multiple cortical and subcortical loops. Some of these loops are believed to be responsible for saccade target selection.

Spatial frequency sensitivity in macaque midbrain

open access: yesNature 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.

Effective connectivity in subcortical visual structures in de novo Patients with Parkinson’s Disease

open access: yesNeuroImage: Clinical, 2022
Background: Parkinson’s disease (PD) manifests with the appearance of non-motor symptoms before motor symptoms onset. Among these, dysfunctioning visual structures have recently been reported to occur at early disease stages.

The functional role of GABA and glycine in monaural and binaural processing in the inferior colliculus of horseshoe bats [PDF]

open access: yes, 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

open access: yesFrontiers 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 ...

Anatomical Studies on Conduction Pathways of Advcrsive Movement [PDF]

open access: yes, 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 Control of Vibrissa Movements [PDF]

open access: yesJournal 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 ...
