A Scientific Approach to Conscious Experience, Introspection, and Unconscious Processing: Vision and Blindsight

open access: yesBrain Sciences, 2022
Although subjective conscious experience and introspection have long been considered unscientific and banned from psychology, they are indispensable in scientific practice. These terms are used in scientific contexts today; however, their meaning remains

“Mickey Mousing” in the Brain: Motion-Sound Synesthesia and the Subcortical Substrate of Audio-Visual Integration

open access: yesFrontiers in Human Neuroscience, 2021
Motion-sound synesthesia is characterized by illusory auditory sensations linked to the pattern and rhythms of motion (dubbed “Mickey Mousing” as in cinema) of visually experienced but soundless object, like an optical flow array, a ball bouncing or a ...

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

open access: yesJ 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.

Morphological study of the pineal gland of Alouatta belzebul

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2022
The pineal is a neuroendocrine gland responsible for the synthesis and release of melatonin. It is present in the brain of vertebrates, but its morphology and location vary considerably among species.

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

open access: greenBrain 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.

Increase by visual stimuli in turnover of 5‐hydroxytryptamine in the superior colliculi of the rabbit.

open access: greenThe Journal of Physiology, 1976
1. Irregular light falshes were played on to one eye of dark adapted rabbits for periods of 20‐80 min. The concentration of 5‐hydroxyindol‐3‐ylacetic acid (5‐HIAA) and of 5‐hydroxytryptamine (5‐HT) were estimated in left and right superior colliculi, thalami and hippocampi. 2.

Face of giant panda sign in space-occupying lesion of brain

open access: yesMedical Journal of Dr. D.Y. Patil Vidyapeeth, 2019
Face of giant panda sign is classically described in Wilson's disease. It is because of high signal intensity in the tegmentum of midbrain with preserved normal signal intensity in the red nuclei, lateral portion of the pars reticulata of the substantia ...

Call‐specific patterns of neural activation in auditory processing of Richardson’s ground squirrel alarm calls

open access: yesBrain and Behavior, 2020
Introduction Richardson's ground squirrels use alarm calls to warn conspecifics about potential predatory threats. Chirp calls typically indicate high levels of threat from airborne predators, while whistle calls are associated with lower levels of ...

The Influence of a Memory Delay on Spatial Coding in the Superior Colliculus: Is Visual Always Visual and Motor Always Motor?

open access: yesFrontiers in Neural Circuits, 2018
The memory-delay saccade task is often used to separate visual and motor responses in oculomotor structures such as the superior colliculus (SC), with the assumption that these same responses would sum with a short delay during immediate “reactive ...

Assesment of Superior Colliculus in Audiogenic Epilepsy-Prone Wistar Rats Using A Stereological Method

open access: yesArchives of Epilepsy, 2017
Objectives:Audiogenic seizures are generated in the brainstem and involve the inferior and superior colliculi in their expression. Aim of the present study was to estimate total number of neurons in the right and left superior colliculi in genetically ...
