کولیکولوس فوقانی
کولیکولوس فوقانی (به انگلیسی: Superior Colliculus) (مشتق شده از لاتین به معنای "تپه فوقانی" یا بالایی) ساختاریست که روی بام میان‌مغز پستانداران قرار دارد. در مهره‌داران غیر-پستاندار، ساختار هم‌ساخت‌شناسانه ی کولیکولوس فوقانی را به نام تکتوم بینایی یا لوب بینایی می شناسند. اغلب صفت تکتال را برای هردو ساختار به کار می برند.

در پستانداران، کولیکولوس فوقانی، مؤلفه اصلی میان‌مغز را تشکیل می دهد. این ساختار به صورت جفت شده بوده و با جفت ساختارهای کولیکولوس تحتانی اجسام چهارقلو را تشکیل می دهند.
