High-Accuracy Detection of Neuronal Ensemble Activity in Two-Photon Functional Microscopy Using Smart Line Scanning

Cell Reports, 2020
Summary: Two-photon functional imaging using genetically encoded calcium indicators (GECIs) is one prominent tool to map neural activity. Under optimized experimental conditions, GECIs detect single action potentials in individual cells with high ...

Astrocyte GluN2C NMDA receptors control basal synaptic strengths of hippocampal CA1 pyramidal neurons in the stratum radiatum

eLife, 2021
Experience-dependent plasticity is a key feature of brain synapses for which neuronal N-Methyl-D-Aspartate receptors (NMDARs) play a major role, from developmental circuit refinement to learning and memory.

Neural coding of numerousness

Biosystems, 2023
Perception of numerousness, i.e. number of items in a set, is an important cognitive ability, which is present in several animal taxa. In spite of obvious differences in neuroanatomy, insects, fishes, reptiles, birds, and mammals all possess a "number sense". Furthermore, information regarding numbers can belong to different sensory modalities: animals

Zebrafish capable of generating future state prediction error show improved active avoidance behavior in virtual reality

Nature Communications, 2021
Using a closed-loop virtual reality system for fish, the authors show that zebrafish are capable of assigning rules to the scenery they see, and of generating a state prediction error by comparing reality with a prediction derived from an internal model.

Robust and efficient representations of dynamic stimuli in hierarchical neural networks via temporal smoothing

Frontiers in Computational Neuroscience, 2023
IntroductionEfficient coding that minimizes informational redundancy of neural representations is a widely accepted neural coding principle. Despite the benefit, maximizing efficiency in neural coding can make neural representation vulnerable to random ...

Identification and analysis of odorant receptors expressed in the two main olfactory organs, antennae and palps, of Schistocerca americana

Scientific Reports, 2022
Locusts depend upon their sense of smell and provide useful models for understanding olfaction. Extending this understanding requires knowledge of the molecular and structural organization of the olfactory system.

Phase information is conserved in sparse, synchronous population-rate-codes via phase-to-rate recoding

Nature Communications, 2023
Neural computation is often traced in terms of either rate- or phase-codes. However, most circuit operations will simultaneously affect information across both coding schemes. It remains unclear how phase and rate coded information is transmitted, in the

The Neural Code of the Retina [PDF]

Neuron, 1999
Finally, the analysis of retinal processing will benefit greatly from the fruitful application of information theory. It has long been recognized that the essential substance transmitted by neurons is not electric charge or neurochemicals, but information (MacKay and McCulloch 1952xThe limiting information capacity of a neuronal link.

Extended field-of-view ultrathin microendoscopes for high-resolution two-photon imaging with minimal invasiveness

eLife, 2020
Imaging neuronal activity with high and homogeneous spatial resolution across the field-of-view (FOV) and limited invasiveness in deep brain regions is fundamental for the progress of neuroscience, yet is a major technical challenge.
