NEW OBSERVATIONS ON THE ANATOMY OF THE FOSSIL CALCAREOUS ALGA SUBTERRANIPHYLLUM ELLIOTT
Rivista Italiana di Paleontologia e Stratigrafia, 2000 New specimens of Subterraniphyllum thomasii Elliott collected from the Oligocene Molare Formation outcropping close to Alessandria (northern Italy) and studied in thin sections and by SEM showed that primary pit-connections, cell fusions, uniporate ...

Modeling the Possible Influences of Eye Movements on the Refinement of Cortical Direction Selectivity [PDF]
, 2004 The second-order statistics of neural activity was examined in a model of the cat LGN and V1 during free-viewing of natural images. In the model, the specific patterns of thalamocortical activity required for a Bebbian maturation of direction-selective ...

Brain Imaging Phenotypes Associated with Polygenic Risk for Essential Tremor
Movement Disorders, EarlyView.Abstract Essential tremor (ET) is a common movement disorder with a strong genetic basis. Magnetic resonance imaging (MRI), particularly diffusion‐weighted MRI (dMRI) and T1 MRI, have been used to identify brain abnormalities of ET patients. However, the mechanisms by which genetic risk affects the brain to render individuals vulnerable to ET remain ...

Meatal Segment of facial nerve and cavernous hemangioma [PDF]
, 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 ...

Anterior Displacement of the Geniculate Ganglion
The Journal of International Advanced Otology, 2016 We present the case of a 34-year-old Japanese woman with cholesteatoma of the middle ear. During the operation, this patient showed an unusual position of the geniculate ganglion. We reviewed the computed tomography (CT) images targeting the ear of the present case after the operation.

Cholinergic System Changes in Dopa‐Unresponsive Freezing of Gait in Parkinson's Disease
Movement Disorders, EarlyView.Abstract Background Freezing of gait (FoG) is a debilitating mobility disturbance that becomes increasingly resistant to dopaminergic pharmacotherapies with advancing Parkinson's disease (PD). The pathophysiology underlying the response of FoG to dopaminergic treatment is poorly understood.

HSV-1 not only in human vestibular ganglia but also in the vestibular labyrinth [PDF]
, 2001 Reactivation of herpes simplex virus type 1 (HSV-1) in the vestibular ganglion (VG) is the suspected cause of vestibular neuritis (VN). Recent studies reported the presence of HSV-1 DNA not only in human VGs but also in vestibular nuclei, a finding that ...

LGN-CNN: a biologically inspired CNN architecture [PDF]
Neural Networks, Volume 145, 2022, Pages 42-55, ISSN 0893-6080, 2019 In this paper we introduce a biologically inspired Convolutional Neural Network (CNN) architecture called LGN-CNN that has a first convolutional layer composed by a single filter that mimics the role of the Lateral Geniculate Nucleus (LGN). The first layer of the neural network shows a rotational symmetric pattern justified by the structure of the net ...
