Astrocytes have long been thought to act as a support network for neurons, with little role in information representation or processing. We used two-photon imaging of calcium signals in the ferret visual cortex in vivo to discover that astrocytes, like neurons, respond to visual stimuli, with distinct spatial receptive fields and sharp tuning to visual stimulus features including orientation and spatial frequency. The stimulus-feature preferences of astrocytes were exquisitely mapped across the… 
Astrocytes in the mouse visual cortex reliably respond to visual stimulation
TLDR
It is demonstrated that astrocytes in the primary visual cortex of awake mice responded to visual stimuli with a delay of several seconds relative to the surrounding neurons, which may indicate the existence of a common mechanism of neuron–astrocyte communication across species.

The Influence of Astrocyte Activation on Hemodynamic Signals for Functional Brain Imaging
TLDR
The spatially restricted, stimulus-specific, blood volume component of hemodynamic signals is exquisitely sensitive to astrocyte but not neuronal activation, demonstrating thatAstrocytes are responsible for a critical component of neurovascular coupling and hemodynamic signaling.
Optogenetic astrocyte activation modulates response selectivity of visual cortex neurons in vivo
TLDR
It is reported that selective photostimulation of astrocytes with channelrhodopsin-2 in primary visual cortex enhances both excitatory and inhibitory synaptic transmission, through the activation of type 1a metabotropic glutamate receptors.
Barrel cortical neurons and astrocytes coordinately respond to an increased whisker stimulus frequency
TLDR
This study reveals that the nerve cells in the barrel cortex encode frequency messages in whisker tactile inputs through setting their activity coordination.
Astrocytes: More than meets the eye
TLDR
It is shown that astrocytes in the primary visual cortex (V1) respond to visual stimuli, and that they are key intermediaries in coupling neural activation to changes in blood flow and haemodynamic regulation in the V1.
Distinct Mechanisms for Visual and Motor-Related Astrocyte Responses in Mouse Visual Cortex
TLDR
It is concluded that cortical astrocytes integrate local sensory information and behavioral state, suggesting a role in information processing.
Neural correlates of single vessel hemodynamic responses in vivo
TLDR
The integrated synaptic or spiking responses around individual parenchymal vessels in cats established that the vascular and neural responses had the same orientation preference, and local neural and hemodynamic signals were partly decoupled.
Astrocytic modulation of information processing by layer 5 pyramidal neurons of the mouse visual cortex
TLDR
It is found that optogenetic activation of astrocytes in the vicinity of layer 5 in the mouse primary visual cortex induce spiking in local pyramidal neurons through Nav1.6 ion channels and prolongs the responses elicited in these neurons by stimulation of their distal inputs in cortical layer 1.
Astrocytes integrate local sensory and brain-wide neuromodulatory signals
TLDR
It is demonstrated that astrocytes in visual cortex of mice encode local visual signals in conjunction with arousal state, functioning as multi-modal integrators, which adds an additional layer of complexity toAstrocyte function and may enable astroCytes to specifically and subtly regulate local network activity and plasticity.

Sensory-Evoked Intrinsic Optical Signals in the Olfactory Bulb Are Coupled to Glutamate Release and Uptake
Functional imaging signals arise from metabolic and hemodynamic activity, but how these processes are related to the synaptic and electrical activity of neurons is not well understood. To provide
Mapping multiple features in the population response of visual cortex
TLDR
Optical imaging of intrinsic signals in ferrets is used to assess patterns of population activity evoked by the motion of a texture and indicates that population activity in primary visual cortex is better described as a single map of spatiotemporal energy.
Synaptic Integration by V1 Neurons Depends on Location within the Orientation Map
TLDR
It is found that neurons near pinwheel centers have subthreshold responses to all stimulus orientations but spike responses to only a narrow range of orientations.
Adaptive filtering enhances information transmission in visual cortex
TLDR
A new information-theoretic method is applied that allows unbiased calculation of neural filters (receptive fields) from responses to natural scenes or other complex signals with strong multipoint correlations and finds that neural filters adaptively change with the input ensemble so as to increase the information carried by the neural response about the filtered stimulus.
Functional imaging with cellular resolution reveals precise micro-architecture in visual cortex
TLDR
It is shown that cortical maps can be built with single-cell precision, and neurons with opposite preferences for stimulus direction were segregated with extraordinary spatial precision in three dimensions, with columnar borders one to two cells wide.
Influence of contrast on orientation and temporal frequency tuning in ferret primary visual cortex.
TLDR
Results show that LGN and cortical neurons experience a contrast-dependent phase advance in their visual response and indicate that subcortical mechanisms likely play a major role in establishing the degree of effect displayed by downstream neurons.
Neuron-to-astrocyte signaling is central to the dynamic control of brain microcirculation
TLDR
In vivo blockade of glutamate-mediated [Ca2+]i elevations in astrocytes reduced the blood flow increase in the somatosensory cortex during contralateral forepaw stimulation and showed that neuron-to-astrocyte signaling is a key mechanism in functional hyperemia.
Detecting action potentials in neuronal populations with calcium imaging.
TLDR
Calcium imaging of neocortical brain slices is used to develop a method to reconstruct the action potentials occurring in a population of neurons, demonstrating that each action potential produces a stereotyped calcium transient in the somata of pyramidal neurons.
Astrocytic Ca2+ signaling evoked by sensory stimulation in vivo
TLDR
It is shown that whisker stimulation evokes increases in astrocytic cytosolic calcium (Ca2+) within the barrel cortex of adult mice, and that increases in Astrocytic Ca2+ occur independently of postsynaptic excitatory activity.
Imaging input and output of neocortical networks in vivo.
TLDR
It is demonstrated that two-photon calcium imaging of bulk-labeled tissue permits dissection of local input and output activities in rat neocortex in vivo, and spontaneous activity in the neocortex is sparse and heterogeneously distributed in space and time across the neuronal population.
