Description

Statement of Requirements

The University of Ottawa is pleased to invite qualified proponents to submit a proposal for a Dual Output Laser System that will
be part of of a 3D Acoustic Optical Deflector (AOD) Based Random Access Multi-Photon (RAMP) Microscope System that will
be used to collect data from custom defined positions at high temporal precision. The primary use of the system will be to monitor
synaptic signals and action potentials from subcellular neuronal compartments and large number of neuronal somas. In addition
to monitoring physiological signals, the system will also be used for stimulating neuronal elements through optogenetic methods
and uncaging. The system must be able to perfrom two-photon RAMP imaging and laser photo-activation system to execute
neuroscience experiments compatible with live cell imaging, voltage imaging and synchronized electrophysiology in brain slices
in vitro and in in vivo experimental designs. The system should be optimized for fast imaging from small custom defined Region
of Interest (ROIs) while simultaneously allowing experimental manipulations (i.e. uncaging).

General Description:

The objective of the research is to understand the physiological processes by which the brain translates incoming information
and code new memories. In order to achieve this, image neuronal activity at a very high speed is required. The microscope
system will be used to monitor neuronal voltage signals at high temporal and spatial resolution. Data obtained with the new
imaging system will expand research aiming to unveil new knowledge about memory formation and spatial navigation using novel
imaging and computational technologies that can be identified in future experiments as therapeutic targets for the treatment of
dementia.

The primary use of this system will be to study a) voltage signals in dendritic compartments and axonal terminals and b)
physiological responses from large number of neurons simultaneously. Imaging will be done in 3D custom defined locations which
could include various locations along the same dendritic tree or identified somas in from a larger volume. The system will be used
for high frequency recording of neural signals from spatially separated and distinct subcellular compartments and for the
synchronous stimulation of multiple synaptic inputs terminating on various dendritic regions at a kilohertz rate. The intended use
of the system will be to detect single action potentials in trains and subthreshold voltage changes in single trials, with sub
millisecond temporal resolution.
