产品名称OmniPlex高通量神经信号采集系统

OmniPlex神经记录数据采集系统是Plex系统结合了前端放大和采集与直观和强大的控制和可视化软件。

描述

OmniPlex 系统是一个紧凑、灵活的高性能数据采集平台和强大的在线spike排序平台。它提供低延迟，优越的共模抑制放大，并以其使用简易而闻名。OmniPlex 系统是由OmniPlex chassis、OmniPlex 软件组成，以及新的OmniPlex 系统，Digital Headstages Processor (DHP) 系统-如下所述。OmniPlex 系统的其他版本可以使用OmniAmp或DigiAmp A/D 设备。

• 紧凑型OmniPlex Chassis有两种尺寸可供选择，架式安装和桌面，并配有用于系统组件、获取子系统链路、数字输入和非神经实验信号辅助模拟输入的卡。  
• OmniPlex系统控制器操作由OmniPlex服务器组成的Omplex软件，OmniPlex 系统控制器运行由OmniPlex 服务器、用于神经信号处理的"软件引擎"和PlexControl组成的 OmniPlex 软件，后者是提供数据可视化和用户界面与系统交互的主要用户界面。
• Digital Headstages Processor （DHP） 的数字Headstages是 Plexon 先进的子系统。DHP 现在可提供 512 个神经记录通道，降低对环境电气噪音的敏感度，以及更轻的Headstages电缆，使电线更少，以增加动物运动的自由度。此外，它提供实时放大至 40KHz 和 multiplexer timing offsets（相当于同步采样）的调整，以改善分拣质量、trodal采集和软件引用——与其他基于数字Headstages的系统不同。或者，DHP 的前身是 Plexon 的 DigiAmp ™模拟Headstages子系统。DigiAmp 数字化放大器有两种尺寸可供选择：MiniDigi ™ 16、32、48 和 64 个频道，DigiAmp 可提供 64、128、192 和 256 个频道。使用模拟Headstages时建议使用此子系统。两者都提供16位A/D转换，每个通道40kHz，用于采集完整的宽带信号。灵活的数字过滤支持各种滤波类型（Bessel, Butterworth, Elliptic, 2-12 poles, plus adaptive power line noise filter）和切断频率，用于从宽频带信号中提取spikes和场位电位，并用于消除噪音。
• DHP 和 DigiAmp 数字化放大器都与电隔离。
• OmniPlex 系统获得的分拣spikes和连续数据可在收集后 1-2 毫秒内提供给外部客户（通过 C/C++ 或 MATLAB软件开发套件（SDK）开发）。此图是整个 OmniPlex 系统从spike检测输入到硬件输出（包括在线用户客户端程序）的实际端到端延迟。
• 主机中的 DigiAmps 和所有模块通过高分辨率主正时模块同步。同一主计时模块可以扩展，以便与兼容的设备（如 Plexon 的）同步时间的CinePlex 行为研究系统.
• Plexon 提供各种模拟和数字Headstages以满足适合大型和小型动物的各种急性或慢性研究需求。包括新的 64 和 128 通道高通道计数数字Headstages与新的 Samtec 连接器。
• Headstages 电缆有多种选项可供选择，包括：wire gauge, cable wraps, lengths, connectors and configurations。适当的配置将提高您的录音质量，并保护您的设备。所有Plexon的Headstages电缆均可重复使用。
• Hong Kong Plexon 提供一系列坚固、低扭曲的换向器，可靠地保持多种类型的电缆不缠绕。已设计了通信器，以优化信号传输，并采用特定设计，用于模拟Headstages、数字Headstages和/或光遗传学。
• 了解更多关于OmniPlex系统强大的在线spikes排序软件，该系统具有灵活和可定制的主要用户界面。
• Hong Kong Plexon 销售工程师很乐意讨论您的需求以及 OmniPlex 如何能够好地支持您的电生理研究目标。

软件

PlexControl

PlexControl 是 OmniPlex 系统强大的在线spikes排序软件，具有灵活和可定制的主要用户界面。该软件代表了下一代信号可视化和易于使用的spikes波形分类方法，并允许研究人员与系统交互。它具有易于使用的信号可视化、spike检测和排序算法。有许多spikes排序方法可用，包括：box, template, line, band sorting in time/voltage space and contour sorting in PCA feature space feature space。PlexControl 程序会在每个通道上自动获取用户定义大小的spike波形快照，并可随时查看以根据需要修改spike排序参数。可以根据实时数据的快照或直接实时"绘制"实时数据来定义单位。每种方法可用于在线 single electrodes, stereotrodes and tetrodes排序。

连续spike、场电位和信号可方便地显示在 PlexControl 灵活、可定制的用户界面中，以及检测到的spikes波形段及其相关的二维 （2D） 和三维 （3D） 功能空间集群，用于在线spikes排序。此外，所有三种数据类型以及阈值spike波形段和数字事件数据都可以记录到每个通道的磁盘中。

OmniPlexServer：

OmniPlexServer是PlexControl控制下的"引擎"。它可直观地显示系统中的各种硬件设备（例如headstages, amplifier）和软件模块（例如spike和 LFP 分离器、阈值、排序）。它从 OmniPlex chassis和放大器获取数据，向这些设备发送命令，并实现软件数字信号处理 （DSP），用于 OmniPlex 的过滤、spike检测和spike排序功能。OmniPlex Server 基于模块化、可扩展的框架（或拓扑）硬件和软件设备，这些设备在数据流拓扑中相互连接，利用拓扑向导使用户能够轻松定义自定义配置，而无需繁琐的低级编辑。

OmniPlex 软件与 Hong Kong Plexon 的 MATLABand C/C++ API 和客户端开发套件（SDKs）以及在线神经探索器链接兼容，实现了低延迟、闭环实验和实时数据在线分析。Hong Kong Plexon 的 PlexNet 协议支持跨任何 TCP/IP 或 UDP 网络进行远程在线数据访问，以及用于修改 OmniPlex 软件输出的PlexUtil，还可以进一步加强该功能PLX数据文件。此外，OmniPlex 中的灵活数字过滤功能也纳入离线排序程序，使用户能够将相同的滤镜离线应用到与在线使用的数据持续采样。

OmniPlex 软件，通过购买任何 OmniPlex 系统预加载到控制计算机上。OmniPlex 软件的演示版本（无需 OmniPlex 硬件即可运行）可在此页面顶部找到。
