FRAP Imaging Platform
Big Image Data Solution
New microscopy technologies, such
as light sheet fluorescence microscopy
(LSFM) or clearing methods, allow
the imaging of large samples at high
resolution or high frame rates. Handling,
processing, and analyzing these
multiterabyte data sets has become
increasingly difficult for scientists in fields
such as developmental biology and
neuroscience. New tools are needed to
overcome these challenges. Therefore,
Zeiss has teamed up with Arivis AG
to offer complete solutions from initial
image acquisition to final results.
Arivis Vision4D is a modular software
for handling multidimensional (3D+)
images of nearly unlimited size. Users
can easily import images generated
with microscope systems such as
Zeiss Lightsheet Z.1, and comfortably
stitch and align single images into large
comprehensive image stacks. This
enables easy assessment and efficient
analysis of high resolution brain-mapping
experiments or long-term observation of
developmental processes in embryos, for
example. Zeiss is offering an integrated
package worldwide, consisting of Arivis
Vision4D software and certified highperformance computer hardware.

Wireless Transmitter/Receiver
The MOVE wireless system is a solution
PET/SPECT/CT System
A proprietary gridless positron emission
tomography (PET) detector architecture
makes the Albira Si the most advanced
preclinical PET system on the market. It
delivers submillimeter spatial resolution
across the full radial field of view (FOV),
increasing the high-resolution FOV by
an order of magnitude, as compared to
traditional PET systems. This capability,
combined with high count-rate performance and high PET sensitivity, makes
Albira Si the preferred system for dynamic
and gated PET in vivo studies. The Albira
Si offers all the benefits of integration
with single-photon emission tomography
(SPECT) and computed tomography (CT).
The microCT provides anatomical reference images and attenuation corrections
for PET and SPECT imaging. In addition,
the Albira Si is compatible with Bruker’s
multimodal animal beds for cross-platform
magnetic resonance imaging (MRI) and
optical molecular imaging. Also, the new
BioSpec 3T PET/MRI further combines the
Albira Si’s PET detector technology with
superior MRI soft-tissue contrast. Bruker

that replaces the existing cables
connecting the electrodes and amplifier
in electoencephalography (EEG) systems
with wireless-based communication.
This solution allows the subject to move
freely and makes it very suitable for
use with a brain-computer interface,
neurofeedback, and motor learning.
Paradigms that cannot be used with
standard cabled EEG systems can
now be incorporated into day-to-day
research, and normal experiments
will become more convenient for the
participants. The small, lightweight transmitter box and receiver can
be used with virtually any existing amplifier/electrode combination.
The transmitter amplifies and digitizes the incoming raw analog
signal and sends it to the receiver, where the digital data is
converted back to analog. If the data is not received properly, the
receiver unit will send a transistor-transistor logic (TTL) pulse marker
to the amplifier, and a marker is sent when stable and reliable data
reception resumes.

Enabling the easy addition of photomanipulation techniques to imaging
platforms, Olympus has launched a new
cellFRAP deck system for the popular
“open source concept” IX83 and IX73
microscopes. cellFRAP is designed with
researchers in mind, providing highly
accurate and flexible live-cell photomanipulation with various evaluation
options for data presentation needs.
Unlike conventional, widefield-based
fluorescence recovery after photobleaching (FRAP) systems, Olympus’ cellFRAP
employs a diffraction-limited laser spot
for high-intensity and precise positioning of the bleaching region across the
full field of view (FOV). This ensures that
photomanipulation reaches every point
in the FOV without needing to move the
sample. The system’s excellent spot
quality allows full flexibility in the position and shape of the bleaching region,
and enables control of the bleaching
area with extreme accuracy. Driven by
the Olympus real-time controller, the
cellFRAP system achieves an unrivaled
short switchover time of only 200 µs
between bleach and postbleach acquisition, ensuring detection of the most
valuable initial sample response after
stimulation.

Neurophysiological Data Analysis
Package
NeuroExplorer v5.017 is now available
with significant improvements/additions,
including enabling maximum benefit
when working with and saving neural
data files greater than 2 GB, and a new
“Find Oscillations” analysis, which identifies episodes of oscillatory activity in the
specified frequency band in recorded
analog signals. NeuroExplorer is a neurophysiological data analysis package
that supports sophisticated analyses and
generates a professional presentation of
the results. Researchers require the ability to analyze, manipulate,
and save such data in huge files. NeuroExplorer launched its new
.NEX5 file format last year to meet the industry’s growing data demands. This most recent release, v5.017, leverages the increased
flexibility of the .NEX5 format not only to analyze and save files
greater than 2 GB, but also to save unlimited metadata for the
whole file and for every file variable in JavaScript Object Notation
(JSON) format.
