Abstract: A method for synchronizing data transmitted between at least one transmit terminal (TE) and a receive terminal (TR) via a transmission channel (CD) with unmanaged latency, comprising the steps: (a) in said or in each transmit terminal, generating at least one synchronization signal (SSYNC) having a known temporal relationship with the time of transmission of at least one data packet (SEEG) to be synchronized; (b) transmitting said or each data packet to be synchronized on said transmission channel with unmanaged latency, and said or each synchronization signal on an auxiliary transmission channel (CS) with managed latency; (c) in said receive terminal, receiving said or each data packet to be synchronized and said or each synchronization signal; and (d) synchronizing said or each data packet received by said receive terminal by means of said synchronization signal. Data acquisition device for carrying out such a method.

Abstract: The main object of the invention is an implantable device of the neural interface type for processing signals, including: a case intended to be held at least partially in a cavity formed on the cranium of a human or animal, an electronic circuit positioned in the case (B), and a system of electrodes coupled electrically to the electronic circuit, wherein the device includes a signal transmission sleeve, extending from the periphery of the case.
