A computerized analysis of the entire retinal ganglion cell population and its spatial distribution in adult rats [PDF]

open access: yes, 2008
In adult albino (SD) and pigmented (PVG) rats the entire population of retinal ganglion cells (RGCs) was quantified and their spatial distribution analyzed using a computerized technique. RGCs were back-labelled from the optic nerves (ON) or the superior

Geometry of the superior colliculus mapping and efficient oculomotor computation [PDF]

open access: yes, 2007
International audienceNumerous brain regions encode variables using spatial distribution of activity in neuronal maps. Their specific geometry is usually explained by sensory considerations only.

Protracted treatment with MDMA induces heteromeric nicotinic receptor up-regulation in rat brain: an autoradiography study. [PDF]

open access: yes, 2014
Previous studies indicate that 3,4-methylenedioxy-methamphetamine (MDMA, ecstasy) can induce heteromeric nicotinic acetylcholine receptor (nAChR, mainly of α4β2 subtype) up-regulation.

Sex-Specific Brain Deficits in Auditory Processing in an Animal Model of Cocaine-Related Schizophrenic Disorders

open access: yesBrain Sciences, 2013
Cocaine is a psychostimulant in the pharmacological class of drugs called Local Anesthetics. Interestingly, cocaine is the only drug in this class that has a chemical formula comprised of a tropane ring and is, moreover, addictive.

Locus coeruleus complex of the family Delphinidae [PDF]

open access: yes, 2018
The locus coeruleus (LC) is the largest catecholaminergic nucleus and extensively projects to widespread areas of the brain and spinal cord. The LC is the largest source of noradrenaline in the brain.

Development of an AAV-based model of tauopathy targeting retinal ganglion cells and the mouse visual pathway to study the role of microglia in Tau pathology

open access: yesNeurobiology of Disease, 2023
Tauopathy is a typical feature of Alzheimer's disease of major importance because it strongly correlates with the severity of cognitive deficits experienced by patients.

Vergence Neural Pathways: A Systematic Narrative Literature Review. [PDF]

open access: yes, 2016
Research in the neural pathway for vergence is less understood in comparison to the other four visual eye movements. The aim of this study was to review the literature on vergence neural pathways and associated disorders.

Prenatal VPA exposure and changes in sensory processing by the superior colliculus

open access: yesFrontiers in Integrative Neuroscience, 2011
Disorders involving dysfunctional sensory processing are characterized by an inability to filter sensory information, particularly simultaneously arriving multimodal inputs. We examined the effects of prenatal exposure to valproic acid (VPA), a teratogen

Microvascular imaging of the unstained human superior colliculus using synchrotron-radiation phase-contrast microtomography

open access: yesScientific Reports, 2022
Characterizing the microvasculature of the human brain is critical to advance understanding of brain vascular function. Most methods rely on tissue staining and microscopy in two-dimensions, which pose several challenges to visualize the three ...
