Cast side by side inside a crystal-clear, optical-grade acrylic resin block (164 × 78 × 24 mm) are five authentic, professionally dissected vertebrate brain specimens representing the five major vertebrate lineages: Pisces (Fish, 1), Amphibia (Amphibian\/Toad, 2), Reptilia (Reptile\/Lizard, 3), Aves (Bird\/Pigeon, 4), and Mammalia (Mammal\/Rabbit or Rat, 5). Arranged in evolutionary order with clear numbered labels (1–5) along the base, this biological preparation provides an extraordinary direct comparison of primary neuroanatomical structures—from the dominant olfactory bulbs and optic lobes of aquatic and early tetrapod ancestors to the significantly expanded optic tectum and cerebellum of birds, culminating in the highly convoluted cerebral hemispheres and neocortex of mammals. A prestigious visual teaching aid for neuroscience departments, medical neurology training, vertebrate zoology laboratories, and natural history collectors, it enables comprehensive all-angle study without perishable tissue deterioration, formalin odor, or delicate specimen upkeep.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWHY YOU'LL LOVE IT\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eFive Real Vertebrate Brains Side by Side\u003c\/strong\u003e – Features authentic biological brain specimens from fish, amphibian, reptile, bird, and mammal preserved in a single display.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eClear Evolutionary Neuroanatomy Progression\u003c\/strong\u003e – Visually demonstrates the progression of vertebrate cephalization, cerebral cortex expansion, and sensory lobe specialization.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eDetailed Structural Morphologies\u003c\/strong\u003e – Easily examine comparative differences in olfactory tracts, optic lobes, cerebella, brainstems, and mammalian cerebral hemispheres.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eNumbered Comparative Labels (1–5)\u003c\/strong\u003e – Clean sequential numbering beneath each specimen provides effortless visual referencing during classroom lectures and lab demonstrations.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003ePremium Optical-Grade Acrylic Resin\u003c\/strong\u003e – Heavyweight 164 × 78 × 24 mm horizontal block offers crystal clarity and 360-degree observation from every angle.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eOdorless, Safe \u0026amp; Permanently Sealed\u003c\/strong\u003e – Completely solid resin encapsulation seals biological tissues forever, eliminating fluid evaporation and chemical handling hazards.\u003c\/li\u003e\n  \u003cli\u003e✦ \u003cstrong\u003eInvaluable Academic \u0026amp; Medical Display\u003c\/strong\u003e – A remarkable centerpiece for neurologists, neuroscientists, medical students, evolutionary biologists, and curiosity cabinets.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003ePERFECT FOR\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNeuroscience students and researchers, neurology clinics, university biology faculties, AP biology educators, science gift-givers, and natural history collectors.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e E1406\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecimen:\u003c\/strong\u003e 5 Real Vertebrate Brains (Fish, Amphibian, Reptile, Bird, Mammal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Optical-Grade Acrylic Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 164 × 78 × 24 mm (approx. 6.5 × 3.1 × 0.9 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Crystal Clear Resin with Preserved Anatomical Brain Specimens\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Horizontal Rectangular Block with Numbered Labels (1–5)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003e*Notice: Price is for retail.
