Chế tạo tế bào não từ chất dẻoCác nhà khoa học Thụy Điển đã chế tạo thành công tế bào não, một thành tựu có thể mở ra triển vọng mới trong nỗ lực điều trị các bệnh thoái hóa thần kinh.
Chất truyền dẫn thần kinh đưa tín hiệu từ tế bào này sang tế bào khác trong não. Ảnh: usnews.com.Tế bào thần kinh trong não tạo ra và sử dụng các chất truyền dẫn thần kinh (như acetylcholine hoặc dopamine) để truyền tín hiệu từ tế bào này sang tế bào khác. Các nhà khoa học của Viện nghiên cứu Karolinska (Thụy Điển) chế tạo những miếng chất dẻo siêu nhỏ có khả năng dẫn điện rồi cấy chúng vào não chuột lang. Sau đó họ phát một dạng tín hiệu qua những miếng chất dẻo đó.
