Neural images were obtained by scanning an image while recording from a second-order neuron in the fly visual system. Over a 5.5-log-units-wide range of mean intensities, experiment and theory correspond well. At high mean intensities, redundancy in the image is reduced by spatial and temporal...
Ratios of citrine/CFP were calculated using the Fiji distribution of ImageJ software (version 1.52b) (Schindelin et al., 2012). Areas of interest were drawn overlying either a MNT, single axon (innervating an already measured MNT), or axons constituting a small bundle (< 15 μm), medium ...
with a field programmable gate array–graphics processing unit design for an up to 500-megabyte-per-second image stream. Adapted to whole-brain imaging of awake larval zebrafish, the system timely extracts activity from up to 100,000 neurons and enables closed-loop perturbations of neural dynamics...
A Llobet,V Beaumont,L Lagnado - 《Neuron》 被引量: 112发表: 2003年 Sinusoidally phase-modulated interference microscope for high-speed high-resolution topographic imagery We describe an interference microscope that produces topographic images with a minimum acquisition time of 20 ms. The system is ...
All mammalian brains consist of interconnected neurons that transmit electrochemical signals. Neurons have several components: the body, which includes a nucleus and dendrites; axons, which connect to other cells; and axon terminals or synapses, which transmit information or stimuli from one neuron to...
Real-time capture of human motion is of considerable interest in various domains including entertainment and the life sciences. Recent advances in computer vision (e.g. Captury 2017) and the availability of commodity wireless inertial sensors (e.g. Roetenberg et al. 2013; PerceptionNeuron 2017)...
Tracking the firings of individual neurons is like trying to discern who is saying what in a football stadium full of screaming fans. Until recently, neuroscientists have had to tediously track each neuron by hand. "People spent more time analyzing their data to extract activity traces than actu...
enough to generate its own chemicals back. But if the signal comes from a similar imagein future, this one may triggerand will find the chemical connection from the old nearby neuron while generating its own and will trigger an already existing output (part of the pattern of the old image)...
Full size image Animal models currently used in systems and evolutionary neuroscience are diverse and extend from jellyfish42 to monkeys43. To test our method on versatile animal models with different neuron morphologies and brain structures, we imaged in vivo calcium dynamics in the brains of zebra...
