Track‐Weighted Dynamic Functional Connectivity Profiles and Topographic Organization of the Human Pulvinar

open access: yesHuman Brain Mapping, Volume 45, Issue 17, December 1, 2024.
Leveraging diffusion and functional MRI information, we revealed dorsomedial, dorsolateral, ventral anterior, and ventral posterior connectivity clusters within the human pulvinar. While it was not possible to find a perfect match between connectivity‐based clusters and histological nuclei, each pulvinar cluster shows functional coupling to specific ...

Evaluating the In Vivo Specificity of [18F]UCB-H for the SV2A Protein, Compared with SV2B and SV2C in Rats Using microPET

open access: yesMolecules, 2019
The synaptic vesicle protein 2 (SV2) is involved in synaptic vesicle trafficking. The SV2A isoform is the most studied and its implication in epilepsy therapy led to the development of the first SV2A PET radiotracer [18F]UCB-H.

Exploring amyotrophic lateral sclerosis through the visual system: A systematic review

open access: yesEuropean Journal of Neurology, Volume 31, Issue 12, December 2024.
Abstract Background and Purpose The human visual system relies on neural networks throughout the brain that are easily accessible for tests exploring eye structures and movements. Over the past two decades, investigations have been carried out on both afferent and efferent components of the visual system in people with amyotrophic lateral sclerosis ...

One hundred ways to process time, frequency, rate and scale in the central auditory system: a pattern-recognition meta-analysis

open access: yesFrontiers in Computational Neuroscience, 2015
The mammalian auditory system extracts features from the acoustic environment based on the responses of spatially distributed sets of neurons in the subcortical and cortical auditory structures.

In Vivo 3D Digital Atlas Database of the Adult C57BL/6J Mouse Brain by Magnetic Resonance Microscopy [PDF]

open access: yes, 2008
In this study, a 3D digital atlas of the live mouse brain based on magnetic resonance microscopy (MRM) is presented. C57BL/6J adult mouse brains were imaged in vivo on a 9.4 Tesla MR instrument at an isotropic spatial resolution of 100 μm.

Measurement of Anteroposterior diameters of normal brainstem by Magnetic Resonance Imaging

open access: yesJournal of Gandaki Medical College, 2019
Aim: The aim of this study is to assess the anteroposterior diameter of brainstem (midbrain, pons and medulla) of normal Nepalese people to establish normal ranges and to correlate the measurement with pa­tient’s age and gender. Method: The study is a

Distribution of melanopsin positive neurons in pigmented and albino mice: evidence for melanopsin interneurons in the mouse retina. [PDF]

open access: yes, 2014
Here we have studied the population of intrinsically photosensitive retinal ganglion cells (ipRGCs) in adult pigmented and albino mice. Our data show that although pigmented (C57Bl/6) and albino (Swiss) mice have a similar total number of ipRGCs, their ...

Direct Monitoring of Whole‐Brain Electrodynamics via High‐Spatiotemporal‐Resolution Photoacoustics with Voltage‐Sensitive Dye

open access: yesLaser &Photonics Reviews, Volume 18, Issue 10, October 2024.
This work proposes a novel method for monitoring deep‐brain electrodynamics with a voltage‐sensitive dye (VSD)‐based photoacoustic imaging platform, called PA‐VSD. This platform is demonstrated to allow for effectively localizing epileptic foci and visualizing voltage conduction pathways in a high spatiotemporal resolution. Abstract Brain voltage plays

Transcortical photothrombotic pyramidotomy model with persistent motor deficits.

open access: yesPLoS ONE, 2018
Traditional pyramidotomy models have a high mortality rate from breathing difficulties and show early recovery from the induced motor deficits. This study establishes a novel pyramidotomy technique in Sprague Dawley rats that generates persistent motor ...
