New V-Probe and CinePlex 3.4 Release

Plexon’s newsletter from February 28, 2013 discussing the new V-Probe and release of CinePlex 3.4.

Announcing the NEW V-Probe

Plexon is pleased to announce the new V-Probe multi-site, linear array! The V-Probe takes the best of the very popular U-Probe to the next level. As you have come to expect, it is exceptionally durable, highly customizable, and often used in acute research with medium to large animals. Uniquely, the probe shaft has been redesigned to further minimize trauma to the brain tissue upon insertion through the implementation of a conical-shaped tip.

The V-Probe is available in 8, 16, 24 and 32 channel configurations, in lengths up to 150mm, and with a choice of 15, 20, 25 or 40µm diameter recording sites. You also have the flexibility of integrating a fluid channel or an optic fiber at various locations.

V-Probes are compatible with Plexon’s PlexDrive™ Microdrive for advancing a single or multiple probes. Contact for more information.

CinePlex® 3.4 Now Released

Great news for CinePlex® Behavioral Research System users – the newest software release is now available! CinePlex Studio now permits recording from the ATV Pike 100c camera with 960 x 960 resolution at up to 60 frames per second, and CinePlex Editor accommodates those files.

CinePlex Tracking has been significantly enhanced via advanced color marker tracking algorithms for greater tracking accuracy and advanced detail filtering for whole body tracking. In CinePlex Basic Behavior, thresholds for events are now in frames instead of milliseconds for more specificity, researchers now have the ability to change dwell time thresholds for events while recording, and the angle can be computed between any two custom vectors for angle-based events. CinePlex 3D now accommodates LED tracking and expands the possible camera positions to include recording from beneath the experimental area or from the sides.

The new release installation files are available online either on the CinePlex Software page or via Software Downloads.
