Conservation of Neuron-Astrocyte Correlated Activity in Developing Sensory Pathways. [PDF]

open access: yesGlia
Astrocytes and neurons in the superior colliculus exhibit spatiotemporal correlated activity before eye opening. Each neuronal wave is followed by a calcium wave in astrocytes. Spillover of glutamate activates mGluR5 and mGluR3 in astrocytes. ABSTRACT Neurons in developing sensory organs exhibit prolonged burst firing before the onset of sensory ...

Inside the head of Crotalus durissus LINNAEUS, 1758 (Serpentes, Viperidae, Crotalinae): Macroscopic description of the brain with ontogenetic insights. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Neuroanatomy studies in vertebrates have garnered significant attention in recent years, particularly driven by advancements in computerized tomography imaging techniques. Nonetheless, these advancements remain largely constrained to specific vertebrate groups, notably mammals, birds, and fish, leaving studies in reptiles at an incipient stage.

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

open access: yesFrontiers 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 ...

Combining Stimulation Protocols to Probe Memory Consolidation-Commentary on Hausdorf et al. 2025. [PDF]

open access: yesEur J Neurosci
ABSTRACT A recent study by Hausdorf et al. reported that combining closed‐loop acoustic stimulation with transcranial direct current stimulation during sleep does not improve memory consolidation. This contrasts with past studies that reported a beneficial effect of each method individually.

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 ...

Functional MRI of postnatal visual development in normal rat superior colliculi [PDF]

open access: yes2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009
This study employed blood oxygenation level-dependent functional MRI (BOLD-fMRI) to evaluate the visual responses in the superior colliculus of the developing rat brain from the time of eyelid opening to adulthood. Upon flash illumination to the contralateral eye, the regional BOLD response underwent a systematic increase in amplitude with age ...

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.

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 ...
