In vivo Probabilistic Structural Atlas of the Inferior and Superior Colliculi, Medial and Lateral Geniculate Nuclei and Superior Olivary Complex in Humans Based on 7 Tesla MRI

open access: yesFrontiers in Neuroscience, 2019
Despite extensive neuroimaging research of primary sensory cortices involved in auditory and visual functions, subcortical structures within these domains, such as the inferior and superior colliculi, the medial and lateral geniculate nuclei and the ...

Stochastic Nanoscale Biophysical Cues as a Basis for the Induction of Glioblastoma‐Like Transcriptional Programs in Astrocytes

open access: yesAdvanced Science, Volume 13, Issue 20, 9 April 2026.
Stochastic nanoscale physical cues induce glioblastoma (GBM)‐associated transcriptional traits in naïve astrocytes leading to spontaneous formation of spheroids. Cells within spheroids express activated‐MMP2 and a differential gene expression pattern involving P53 and NOTCH3, providing evidence for a role for changes in brain topography, as observed in

Seeing without a Scene: Neurological Observations on the Origin and Function of the Dorsal Visual Stream

open access: yesJournal of Intelligence
In all vertebrates, visual signals from each visual field project to the opposite midbrain tectum (called the superior colliculus in mammals). The tectum/colliculus computes visual salience to select targets for context-contingent visually guided ...

Expression of neuronal nitric oxide synthase in the developing superficial layers of the rat superior colliculus

open access: yesBrazilian Journal of Medical and Biological Research, 2004
We investigated the level of expression of neuronal nitric oxide synthase (nNOS) in the retinorecipient layers of the rat superior colliculus during early postnatal development. Male and female Lister rats ranging in age between the day of birth (P0) and

Target Selection by Frontal Cortex During Coordinated Saccadic and Smooth Pursuit Eye Movement [PDF]

open access: yes, 2007
Oculomotor tracking of moving objects is an important component of visually based cognition and planning. Such tracking is achieved by a combination of saccades and smooth pursuit eye movements.

Nps‐Expressing Neurons Receive Extensive Input From Auditory Brainstem Nuclei

open access: yesJournal of Comparative Neurology, Volume 534, Issue 4, April 2026.
Nps‐expressing neurons receive input from auditory brainstem nuclei, with additional afferents from the reticular formation, midbrain, hypothalamus, and extended amygdala. While rabies retrograde labeling in the cerebral cortex was sparse, cholera toxin beta (CTb) revealed copious input, and anterograde tracing identified many axons and boutons ...

Encoding of Intention and Spatial Location in the Posterior Parietal Cortex [PDF]

open access: yes, 1995
The posterior parietal cortex is functionally situated between sensory cortex and motor cortex. The responses of cells in this area are difficult to classify as strictly sensory or motor, since many have both sensory- and movement-related activities, as ...

Rat superior colliculus encodes the transition between static and dynamic vision modes

open access: yesNature Communications
The visual continuity illusion involves a shift in visual perception from static to dynamic vision modes when the stimuli arrive at high temporal frequency, and is critical for recognizing objects moving in the environment.

Stereological analysis of the vascular network in superior colliculi [PDF]

open access: yesScripta Medica, 2020
Background/Aim: Superior colliculi have an important role in the visual system, some motor functions and behaviour. Branches of the posterior cerebral artery and surrounding vessels form a collicular arterial network, which gives rise to several ...
