Abstract:  Mind reading through brairrcomputer interface (BCI) is in essence of neural decoding. Recent study cases concern functional areas of the cerebral cortex such as early visual region, Broca’s area and Wernicke’s area.However these studies typically used complex BCI(for example, fMRI) and implanted
multi-channel BCl(for example，implanted electrode arrays).To ovcrcome these limitations, here we develop a decoding method based on out-hanging one-probe Chinese auricular frontal-lobe-point’s near infrared spectroscope(NIRS)that characterizes the relationship between silent reading in mind
(meditated) isolated Chinese word and auricular frontal-lobrpoint’s mapping NIRS activity from Broca’ s area(called speech centre).This method is grasped in principles of auricle brain mapping (neurovascular-coupling links from Broca’s area to Chinese auricular frontal-lobe-point called Antitragus
Point 1,AT1)，optical life window (active 875 nm wave-length at high absorption factor for O_^xy H_^b in about 90%oxygen saturation buried in tissues at ATl)，and basic BCl test paradigm. We show that this compact BCl method makes it possible to identify silent reading (in mind) word SHE/HE in voice[ta]or
YOU([ni])，or I([wo]).Identification signatures extracted in(frequency-or) time-domain can touch 70%high level decoding positive recognition rate for 4-subject under the one-probe non-filter sensor kit and Agilent 54624A oscilloscope and PC (running Excel 546000 Toolbar and MATLAB 7. 0).The time
domain signatures of three words lock in differences of main discharge series(tonic potentials as vowel- signs) linking low series (transition potentials as consonant signs). Our results suggest that it may soon be possible to let acquired aphasia speak with car by indirect noninvasive on}probe measurements of
speech cortex activity under silent reading in mind.
