The European Commission has responded to criticism of its billion-euro Human Brain Project, declaring confidence that objections will be satisfied.
The statement also defends the ability of the project to set its own scope, which critics have said is too narrow.
But it says new recommendations for management of the HBP and the balance between its core and partner projects (both contentious issues) are expected in September.
Critics cautiously welcomed the reply.
Under the heading "no single roadmap for understanding the human brain", Robert Madelin (the relevant director-general within the EC) responded directly to last week's open letter.
"As a public funding agency, we take all such signals seriously," he wrote. "We welcome debate."
