Distribution of calcium-binding proteins in the chick visual system

open access: yesBrazilian Journal of Medical and Biological Research, 1997
The calcium-binding proteins calbindin (CB), calretinin (CR), and parvalbumin (PV) have been extensively studied over the last decade since they appear to be important as buffers of intracellular calcium.

Automated FRAP microscopy for high‐throughput analysis of protein dynamics in chromatin organization and transcription

open access: yesFEBS Open Bio, EarlyView.
RoboMic is an automated confocal microscopy pipeline for high‐throughput functional imaging in living cells. Demonstrated with fluorescence recovery after photobleaching (FRAP), it integrates AI‐driven nuclear segmentation, ROI selection, bleaching, and analysis.

A neurobiological and computational analysis of target discrimination in visual clutter by the insect visual system. [PDF]

open access: yes, 2009
Some insects have the capability to detect and track small moving objects, often against cluttered moving backgrounds. Determining how this task is performed is an intriguing challenge, both from a physiological and computational perspective.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Retinofugal Projections Into Visual Brain Structures in the Bat Artibeus planirostris: A CTb Study

open access: yesFrontiers in Neuroanatomy, 2018
A well-developed visual system can provide significant sensory information to guide motor behavior, especially in fruit-eating bats, which usually use echolocation to navigate at high speed through cluttered environments during foraging.

Redundancy in the visual system.

open access: yes, 2020
The visual world is full of redundant information. Natural images contain largely the same information across multiple spatial frequency bands and adjacent pixels are strongly correlated. For a system that is concerned with the economical, both in terms of time and resources, processing of vast amounts of data, reducing this data to extract the ...

A taxonomy of program visualization systems

open access: yesComputer, 1993
A taxonomy of program visualization systems that is based on a model of program visualization that maps programs to graphical representations is presented. The taxonomy is illustrated with three program visualization systems representative of research trends: Zeus, Tango, and Pavane. >

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
