Background:

Functional imaging measures neural activity during stimuli or behavior to map receptive fields.
Traditional temporal resolution of receptive fields is limited by slow image acquisition rates.
Individual neuron measurements can occur at precisely known times, even with slow scanning.

Purpose of the Study:

To develop and apply a method for achieving higher temporal resolution in receptive field mapping.
To overcome the limitations imposed by image acquisition rates in functional imaging.
To enable the study of fast neural dynamics previously unresolvable.

Main Methods:

Leveraging the precise timing of individual neural measurements.
Applying a temporal super-resolution method to functional imaging data.
Utilizing existing optical indicators of neural activity without specialized hardware.

Main Results:

Successfully resolved fast voltage and glutamate responses in Drosophila visual neurons.
Extracted high-temporal-resolution calcium receptive fields from mammalian cortical neurons.
Demonstrated the method's applicability across different species and neural populations.

Conclusions:

The temporal super-resolution method significantly enhances the temporal resolution of receptive field mapping.
This technique allows for the study of rapid neural processes previously inaccessible.
The provided code enables easy application to existing functional imaging datasets.
