Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Species Distribution Modeling Predicts Significant Declines in Coralline Algae Populations Under Projected Climate Change With Implications for Conservation Policy

open access: yesFrontiers in Marine Science, 2020
Anthropogenic climate change presents a major challenge to coastal ecosystems. Mass population declines or geographic shifts in species ranges are expected to occur, potentially leading to wide-scale ecosystem disruption or collapse. This is particularly

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).

Psychophysical evidence for two routes to suppression before binocular summation of signals in human vision [PDF]

open access: yes, 2007
Visual mechanisms in primary visual cortex are suppressed by the superposition of gratings perpendicular to their preferred orientations. A clear picture of this process is needed to (i) inform functional architecture of image-processing models, (ii ...

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

open access: yesAnnals 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 ...

Cortical-Like Receptive Fields in the Lateral Geniculate Nucleus of Marmoset Monkeys

open access: yesJournal of Neuroscience, 2013
Most neurons in primary visual cortex (V1) exhibit high selectivity for the orientation of visual stimuli. In contrast, neurons in the main thalamic input to V1, the lateral geniculate nucleus (LGN), are considered to be only weakly orientation selective.

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 ...

Perigeniculate arachnoid cysts and CSF fistulae of the fallopian canal: Histopathologic correlates of a rare clinical entity

open access: yesWorld Journal of Otorhinolaryngology-Head and Neck Surgery, 2021
Cerebrospinal fluid (CSF) fistulae originating from the fallopian canal of the facial nerve is hypothesized to arise due to atypical patterns of subarachnoid space extension into the geniculate ganglion or more distal regions along the intratemporal ...

Robust information propagation through noisy neural circuits [PDF]

open access: yesPLoS Computational Biology 13: e1005497 (2017), 2016
Sensory neurons give highly variable responses to stimulation, which can limit the amount of stimulus information available to downstream circuits. Much work has investigated the factors that affect the amount of information encoded in these population responses, leading to insights about the role of covariability among neurons, tuning curve shape, etc.

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

open access: yesDevelopmental 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.
