Retinal processing: insights from mathematical modelling [PDF]

open access: yesJournal of Imaging, MDPI, In press, 2022
The retina is the entrance of the visual system. Although based on common biophysical principles the dynamics of retinal neurons is quite different from their cortical counterparts, raising interesting problems for modellers. In this paper I address some mathematically stated questions in this spirit, discussing, in particular: (1) How could lateral ...

Meatal Segment of facial nerve and cavernous hemangioma [PDF]

open access: yes, 2014
Cavernous malformations of the internal auditory canal (IAC) are a rare clinical entity. We report a rare case of cavernous hemangioma involving the internal auditory canal and the meatal segment of the facial nerve without any evident lesion to the ...

Improving Adult Vision Through Pathway‐Specific Training in Augmented Reality

open access: yesAdvanced Science, EarlyView.
Traditional perceptual training approaches are limited by stimulus specificity, treatment efficacy, and patient compliance. A novel altered reality (AR) method is developed to enhance pathway‐specific functions in human adults while performing everyday activities.

Brain Differently Changes Its Algorithms in Parallel Processing of Visual Information [PDF]

open access: yes, 2000
Feedback from the visual cortex (Vl) to the Lateral Geniculate Nucleus (LGN) in macaque monkey increase contrast gain of LGN neurons for black and white (B&W) and for color (C) stimuli.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

open access: yesBMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Do retinal ganglion cells project natural scenes to their principal subspace and whiten them? [PDF]

open access: yes, 2016
Several theories of early sensory processing suggest that it whitens sensory stimuli. Here, we test three key predictions of the whitening theory using recordings from 152 ganglion cells in salamander retina responding to natural movies. We confirm the previous finding that firing rates of ganglion cells are less correlated compared to natural scenes ...

Elp1 function in placode‐derived neurons is critical for proper trigeminal ganglion development

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The trigeminal nerve is the largest cranial nerve and functions in somatosensation. Cell bodies of this nerve are positioned in the trigeminal ganglion, which arises from the coalescence of neural crest and placode cells. While this dual cellular origin has been known for decades, the molecular mechanisms controlling trigeminal ...

Facial Nerve Schwannoma: The Rare/Great Mimicker of Vestibular Schwannoma/Neuroma

open access: yesIndian Journal of Radiology and Imaging, 2021
Schwannomas are benign tumors arising from Schwann cells which are a protective casing of nerves, composing myelin sheath and can develop in any nerve where Schwann cells are present. Most common are vestibulocochlear nerve schwannomas.
