The role of frontal eye-fields and superior colliculi in visual search and non-visual search in rhesus monkeys

Behavioural Brain Research, 1982
Rhesus monkeys were tested on a visual search task in which they had to find and retrieve a peanut from a display of visually similar but inedible objects. The speed with which they did so was measured. Animals in which the superior colliculi or frontal eye-fields had been removed took longer to find the peanut than two operated control groups. Animals

Simultaneous unitary neuronal activity in both superior colliculi and its relation to eye movements in the cat

Brain Research, 1986
The analysis of simultaneous unitary neuronal activity related to eye movement and recorded in both superior colliculi has shown a mirror-functioning image. Increase of the frequency discharge in a collicular unit, was associated with a decrease of the frequency discharge in the contralateral superior colliculus unit.

The nature of the visual discrimination impairment after neonatal or adult ablation of superior colliculi in rats

Experimental Brain Research, 1986
The superior colliculi were removed in rats at either one or five days of age or in adulthood. Seven months later they were tested on four successively presented two-choice intensity discriminations. The intensity difference between the discriminanda was reduced across the four problems to encourage choice by comparison.

The Ventral Tectal Longitudinal Column: A Midbrain Nucleus for Modulation of Auditory Processing in the Cochlear Nucleus, Superior Olivary Complex, and Inferior Colliculus. [PDF]

J Comp Neurol
The ventral tectal longitudinal column (TLCv) is a midbrain nucleus thought to provide multisensory modulation of acoustic processing via descending projections to the superior olivary complex. We discovered additional projections from the TLCv to the cochlear nucleus and to the inferior colliculus.

Stereological analysis of vascular network of subcortical auditory centers

Biomedicinska istraživanja, 2022
Introduction. Subcortical auditory centers have several sources of blood supply. Cochlear nuclei are vascularized by the anterior inferior cerebellar artery.

Age-Related Hearing Loss: Sensory and Neural Etiology and Their Interdependence

Frontiers in Aging Neuroscience, 2022
Age-related hearing loss (ARHL) is a common, increasing problem for older adults, affecting about 1 billion people by 2050. We aim to correlate the different reductions of hearing from cochlear hair cells (HCs), spiral ganglion neurons (SGNs), cochlear ...

Corticobasal degeneration preceded by cognitive impairment and apathy: An autopsy case report. [PDF]

PCN Rep
Abstract Background Corticobasal degeneration (CBD) presents with a range of clinical phenotypes, making diagnosis challenging. We report the clinical course of a patient with autopsy‐confirmed CBD who initially presented with cognitive impairment and apathy, without motor symptoms.
