Our products are used in a wide variety of research applications, including electroencephalography (EEG), evoked potentials (EP), event-related potentials (ERP), brain-computer interface (BCI), electrocardiography (ECG), body-surface potential mapping (BSPM), small animal EEG and many more. A sampling of the applications is below, and under each you will find a list of the main products we offer for these applications.
A Brain-Computer Interface (BCI) provides a new communication channel between the human brain and the computer. Mental activity leads to changes of electrophysiological signals like the Electroencephalogram (EEG) or Electrocorticogram (ECoG). The BCI system detects such changes and transforms it into a control signal which can, for example, be used as spelling device or to control a cursor on the computer monitor.
Cortech just may have been derived from Cor or Cordis, Latin for the heart. Our advanced systems have been designed for brain research applications, but they are especially well-suited to cariac applications, especially when coupled with award-winning analysis software.
The event-related potential, known as the ERP, is an average EEG response to an external event, and it is distinguished from an evoked potential by the fact that part of the ERP comes from the brain activity associated with cognitive activity involved in processing a stimulus or preparing an action. ERP provides a low-cost, non-invasive tool with high temporal precision for measuring functional brain activity.
Although the majority of our products are designed for use in human research, many of the technologies in the human systems are well-suited to animal applications. The unique requirements for data acquisition systems to be used in animal research include high input impedance, the ability to acquire data from multiple animals/preparations at once, the ability to integrate motion tracking and/or activity monitoring, compatibility with implanted electrodes made of platinum and other materials.
