Functional representation of vision within the mind: A visual consciousness model based in 3D default space [PDF]

, 2015
The human eyes and brain, which have finite boundaries, create a ‘‘virtual’’ space within our central nervous system that interprets and perceives a space that appears boundless and infinite.

Anatomical origins of ocular dominance in mouse primary visual cortex [PDF]

, 2009
Ocular dominance (OD) plasticity is a classic paradigm for studying the effect of experience and deprivation on cortical development, and is manifested as shifts in the relative strength of binocular inputs to primary visual cortex (V1).

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

Developmental 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 ...

Spatiotemporal distribution of neural crest cells in the common wall lizard Podarcis muralis

Developmental Dynamics, EarlyView.
Abstract Background Neural crest cells (NCCs) are migratory embryonic stem cells that give rise to a diverse set of cell types. Here we describe the dynamic distribution of NCCs in developing embryos of the common wall lizard Podarcis muralis inferred from 10 markers.

Key concepts, methods, findings, and questions about traumatic memories

Journal of Traumatic Stress, EarlyView.
Abstract This article is based on a Lifetime Achievement Award lecture delivered at the 40th Annual Meeting of the International Society for Traumatic Stress Studies in Boston (Massachusetts, United States) in September 2024. Understanding traumatic memory involves integrating clinical observations with a wide range of knowledge from philosophy ...

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 ...

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.

A new framework for Euclidean summary statistics in the neural spike train space [PDF]

Annals of Applied Statistics 2015, Vol. 9, No. 3, 1278-1297, 2015
Statistical analysis and inference on spike trains is one of the central topics in the neural coding. It is of great interest to understand the underlying structure of given neural data. Based on the metric distances between spike trains, recent investigations have introduced the notion of an average or prototype spike train to characterize the ...

New species and new records in Agarista (Ericaceae) from the Peruvian Andes

Nordic Journal of Botany, EarlyView.
Agarista (Ericaceae) is currently represented in Peru by three species. Here, we update this number to five, adding new taxa based on the recognition of a taxonomic novelty and new records. The new species Agarista eugeniifolia differs from all congeneric species by an abaxially sulcate midvein.

Gating Input to Visual Cortex by Feedback to LGN [PDF]

, 1998
Anatomical studies have documented massive back-projections from higher to lower visual cortices and to the lateral geniculate nucleus (LGN). The large number of synapses from these sources suggest that they should have a profound influence on the ...
