BRAIN NAVIGATION METHODS AND DEVICE

A system for differential recording connectable to an electrical lead with at least two electrodes, including: the lead having a distal end; at least one amplifier electrically connectable to the at least two electrodes, wherein the at least one amplifier subtracts a signal recorded by one of the at least two electrodes, from a signal recorded by the other one of the at least two electrodes to generate a differential signal; a memory configured for storing said differential signal and reference indications of electrical signals associated with neural tissue; a processing circuitry for detection of an anatomical position, wherein the processing circuitry calculates an anatomical position of the electrical lead based on processing of the differential signal and the reference indications of electrical signals associated with the neural tissue. 一种用于差分记录的系统，可连接到具有至少两个电极的电导联，包括：导联，具有远端；至少一个放大器，可电连接到所述至少两个电极，其中所述至少一个放大器从由所述至少两个电极中的一个电极记录的信号中减去由所述至少两个电极中的另一个记录的信号以生成差分信号；存储器，被配置用于存储所述差分信号和与神经组织相关联的电信号的参考指示；用于检测解剖位置的处理
