However, the spatial limitations of fast-scan cyclic voltammetry (FSCV) and spatial and temporal limitations of microdialysis narrow our ability to interpret how neuromodulators affect the plasticity or function of individual neurons and synapses. The absence of direct change in ionic flux across cell membranes, which is measurable using available tools such as electrophysiology or genetically encoded voltage indicators, has necessitated the use of methods borrowed from analytical chemistry such as microdialysis and amperometry to study the dynamics of neuromodulation. Thus, modulatory neurotransmitter activity extends beyond single synaptic partners and enables small numbers of neurons to modulate the activity of broader networks ( 20). In contrast, neuromodulators (catecholamines and neuropeptides) may diffuse beyond the synaptic cleft and act via extrasynaptically expressed metabotropic receptors ( 14– 19). In synaptic glutamatergic and GABAergic neurotransmission, neurotransmitter concentrations briefly rise in the synaptic cleft to mediate local communication between the pre- and postsynaptic neurons through the rapid activation of ligand-gated ion channels ( 13). It does not store any personal data.Modulatory neurotransmission is thought to occur on a broader spatial scale than classic neurotransmission, the latter of which is largely mediated by synaptic release of the amino acids glutamate (GLU) and γ-aminobutyric acid (GABA) in the central nervous system.

The NINOX 640 also features an on-board intelligent 3 point Non Uniform Correction (NUC) algorithm which will provide the highest quality images.Īpplications that can be used with the NINOX 640 including hyperspectral imaging, semiconductor inspection, solar cell inspection, astronomy, telecommunications and thermography. A new feature On-board Automated Gain Control (AGC) will enable clear video in all light conditions. Available with a 14 bit CameraLink output, the NINOX 640 will run from 10 to 120Hz enabling high speed digital video. The 15µm x 15µm pixel pitch enables highest resolution imaging. Using a 640 x 512 InGaAs sensor from SCD, the NINOX 640 offers visible extension from 0.4µm to 1.7µm to enable high sensitivity imaging. The NINOX 640 is cooled to -20✬ offering both TEC and water cooling options, significantly reducing dark current and enabling longer exposures. Raptor Photonics, a global leader in the design and manufacture of high performance digital cameras has launched an additional member to its family of SWIR and Visible SWIR cameras. Raptor launches the NINOX 640, a cooled VIS-SWIR InGaAs camera October 2014
