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

Frontiers 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

The lateral geniculate nucleus [PDF]

Current Biology, 2001
The detailed circuitry of the LGN, its connections, and the fact that the stimulus preferences of geniculate neurons seem identical to those of their retinal inputs make it clear that this nucleus is concerned with regulating the way in which visual information gains access to the cortex rather than with performing visual processing.

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 ...

The influence of irradiance and interspecific differences on δ¹¹B, δ¹³C and elemental ratios in four coralline algae complexes from Aotearoa, New Zealand [PDF]

Biogeosciences
Coralline algae are a cosmopolitan group of important foundational species. The calcium carbonate they produce is increasingly being used as paleoenvironmental archives, as well as used to trace physiological responses of these important macroalgae to ...

Blindsight depends on the lateral geniculate nucleus

Nature, 2010
Injury to the primary visual cortex (V1) leads to the loss of visual experience. Nonetheless, careful testing shows that certain visually guided behaviours can persist even in the absence of visual awareness.

Variation of connectivity across exemplar sensory and associative thalamocortical loops in the mouse

eLife, 2020
The thalamus engages in sensation, action, and cognition, but the structure underlying these functions is poorly understood. Thalamic innervation of associative cortex targets several interneuron types, modulating dynamics and influencing plasticity.

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

Journal 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.

A new species of Paratanais Dana, 1852 (Crustacea, Peracarida, Tanaidacea, Paratanaidae) from Puerto Rico, northwestern Atlantic

ZooKeys, 2014
Paratanais rosadi sp. n. described from Puerto Rican coastal waters represents the first species of the genus from the northwestern Atlantic. It is distinguished from the other Paratanais species by a combination of characters, including article-2 of the

Efficient Coding of Natural Scenes in the Lateral Geniculate Nucleus: Experimental Test of a Computational Theory

Journal of Neuroscience, 1996
A recent computational theory suggests that visual processing in the retina and the lateral geniculate nucleus (LGN) serves to recode information into an efficient form (Atick and Redlich, 1990).
