Our findings suggest that the perforant pathway, the major way to obtain cortical afferent input into the hippocampus, could be preferable as the site of deep-human brain stimulation for memory improvement. In fact, this is further supported by a scholarly study in rodents that was published following the completion of the present study.36 An important facet of the memory-enhancing stimulation in this scholarly study was its application during the learning phase. This suggests that by using neuroprosthetic devices aimed at cognitive enhancement, stimulation may not need to be applied continuously but only once patients are attempting to learn important information.CONSOLIDATED Outcomes FOR THE 90 DAYS ENDED JUNE 30, 2010 Revenues were $5.6 million for the three-month period ended June 30, 2010, compared to $8.4 million for the same period in ’09 2009. The decrease arrives primarily to the absence, this year 2010, of amortization of an upfront license charge payment related to our agreement with sanofi-aventis U.S. LLC, that was entered into in March 2009 and terminated subsequently, in connection with our now discontinued development program regarding cetrorelix for the treating benign prostatic hyperplasia . Research and development costs, net of taxes grants and credits, were $5.0 million for the three-month period ended June 30, 2010, in comparison to $12.1 million for the same period in ’09 2009.
