Visual stimuli outside of the classical receptive field (CRF) can influence the response of neurons in primary visual cortex (V1). While recording single units in cat, we presented drifting sinusoidal gratings in circular apertures of different sizes to investigate this extraclassical surround modulation over time. For the full 2-s stimulus time course, three types of neurons were found: 1) 68%...

One of the core principles of how the mind works is the graded, parallel activation of multiple related or similar representations. Parallel activation of multiple representations has been particularly important in the development of theories and models of language processing, where coactivated representations (neighbors) have been shown to exhibit both facilitative and inhibitory effects on wo...

A facilitative transport system exists on the blood-brain barrier (BBB) that has been tacitly assumed to be a path for glutamate entry to the brain. However, glutamate is a non-essential amino acid whose brain content is much greater than plasma, and studies in vivo show that glutamate does not enter the brain in appreciable quantities except in those small regions with fenestrated capillaries ...

To understand how communities function and generate abundance, I develop a framework integrating elements from the stress gradient and resource partitioning concepts. The framework suggests that guild abundance depends on environmental and spatial factors but also on inter-guild interactions (competitor or facilitator richness), which can alter the fundamental niche of constituent species in ne...

0 We tested predictions about how the e}ect of vegetation and litter on seedling establishment varies among sites and herbaceous community types "sand barrens\ prairies\ fens#[ For both vegetation and litter\ we also separated direct interactions from indirect interactions and interaction modi_cations along the gradient[ 1 Although the intensity of the e}ects varied across sites\ the direct e}e...

Adaptation to climate change and mitigation of climate change are policy substitutes, as both reduce the impacts of climate change. Adaptation and mitigation should therefore be analysed together, as they indeed are, albeit in a rudimentary way, in cost-benefit analyses of emission abatement. However, adaptation and mitigation are done by different people operating at different spatial and temp...

possess a transport system for glucose of the facilitative diffusion type; these transporters allow the movement of glucose across the plasma membrane down its chemical gradient either into or out of cells. These transporters are specific for the D-enantiomer of glucose and are not coupled to any energy-requiring components, such as ATP hydrolysis or a HI gradient [1]. The facilitative glucose ...
