In this paper, different acupoints are stimulated by using pulse stimulating signals with different frequency. The correlation between input signal from acupoints and output signal from brain band is studied. A method to optimize input of acupoints is obtained by an experiment system. And the dynamic connection between meridian and brain band is identified. Experiment has shown that there exists maximal correlation between the signal of 30 Hz intermittent pulse stimulation and the induced cerebral alpha band. And the 30 Hz intermittent pulse stimulation can induce more beneficial cerebral a band.

Objective To observe the outcomes of seizure control by three different surgical approaches,hippocampal transection,anterior temporal lobectomy and selective amygdalo-hippocampectomy,for the treatment of intractable medial temporal epilepsy,and explore their influences in the impairments of cognitive and memorial functions.Methods Twenty-nine patients with intractable medial temporal epilepsy,admitted to our hospital from January 2012 to October 2015,were chosen in our study;8 patients accepted hippocampal transection,10 accepted anterior temporal lobectomy and 11 accepted selective amygdalo-hippocampectomy.Seizure controls after treatment with these 3 approaches were compared and results of neuropsychological examinations (verbal intelligence quotient [VIQ],performance intelligence quotient [PIQ],full intelligence quotient [FIQ] and memory quotient [MQ]) were compared before and after operation.Results The effective rates of seizure controls were all higher than 80% and seizure free rate was about 60% in the 3 groups;Engel grading showed no significant differences among the three groups (P>0.05).Results of all the neuropsychological examinations in the hippocampal transection group before and after operation had no significant differences (P>0.05);however,all results in the anterior temporal lobectomy group after operation were significantly declined as compared with those before operation (P<0.05);and PIQ,FIQ and MQ scores in the selective amygdalo-hippocampectomy group after operation were significantly lower as compared with those before operation (P<0.05).Conclusions Hippocampal transection will not cause significant damage in intelligence and memory functions.As compared with both anterior temporal lobectomy and selective amygdalo-hippocampectomy,hippocampal transection can have good seizure control and preserve memory function.
