Abstract

A portable event associated electrocortical potential instrument for taking the event associated encephaloelectric ERP signals and analyzing them to obtain the actual reaction of the event in brain is composed of cerebral electrodes, encephaloelectric signal amplifier, 16 A / D converters, synchronous controller MCU for reading the data of 16í‡8 channels, notebook computer, and body stimulator.

Description

technical field [0001] The present invention relates to an ERP instrument for research on brain imaging technology, in particular to an ERP instrument that can accurately collect human neurobiological electrical signals for use in brain neuroscience, cognitive psychology, clinical medicine and criminal psychology, etc. Portable event-related EEG instrument for research and application. Background technique [0002] The human brain is a multi-level complex giant system, and its advanced functions are manifested in various psychological activities such as perception, attention, memory, learning, language, thinking, emotion, consciousness, and personality. The relationship between brain-cognition-behavior is the core problem that human beings must solve in the process of understanding themselves. Human beings have always hoped to reveal the secrets of brain activity, and the relationship between brain-cognition-behavior has become the core problem that humans must solve in the...
