Comparative Brains In Lucite (Fish, Frog, Pigeon, Rabbit & Snake)

SKU: GF-099 Categories: ,

This taxidermy animal lucite paperweight contains five brains from five different species. The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. Sponges, jellyfish, adult sea squirts and starfish are among the few invertebrates that don’t have a brain. Instead, they possess diffused or localized nerve nets instead. The brain is the most complex organ in a vertebrate’s body. The brain is usually located close to the primary sense organs for senses such as vision, hearing, balance, taste, and smell.

In a typical human, the cerebral cortex, the largest part of the brain, is estimated to contain 15–33 billion neurons. Each of these neurons is connected by synapses to several thousand other neurons. These neurons communicate with one another through axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells. The shape and size of the brain varies greatly in different species, and identifying common features can be difficult. Human beings do not have the heaviest brains in overall weight, or even weight in proportion to their bodies. Also, the nerve center of the human brain is only slightly more complex than that of animals.

Physiologically, the function of the brain is to exert centralized control over the other organs of the body. The brain acts on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated responses to changes in the environment. Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information integrating capabilities of a centralized brain.

These paperweights are a perfect way to explore these fascinating specimens from every angle without worrying about harming the specimen. Different batches may have a slight yellow tint, but this will not affect the visibility of the specimen.

• You will receive a taxidermy animal lucite paperweight similar to the reference specimen
• Approximately 6.5″ long and 3″ tall (different batches may slightly vary in size)
