Different brains

Although the shape and size of brains vary among different species, there are many similarities in structure, such as neurons being the smallest building blocks and having basic structures such as brainstem. Some brain structures are more developed in species that are more "advanced" in evolution, such as the limbic system responsible for emotions and memory, as well as the cerebral cortex that controls thinking and behavior. In addition, as the fundamental structure of the brain, the brainstem is responsible for basic physiological functions such as respiration and heartbeat, ensuring the maintenance of life and providing support for the development of more complex brain regions.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

The brain is the main part of the central nervous system, located within the cranial cavity. The brains of lower vertebrates are relatively simple. The brains of humans and mammals are particularly developed. The human brain is composed of the brain, cerebellum, diencephalon, and brainstem. The brain is the highest level and main part of the central nervous system. It is divided into two hemispheres of the brain, the left and right, which are connected by the corpus callosum composed of nerve fibers. There are many curved grooves on the surface of the cerebral hemisphere, called sulci, and the protruding part between them is called the gyrus. These sulci and gyri are like a crumpled silk cloth, once flattened, their area is about the size of half a regular newspaper, about 2250cm ². Zebrafish brain: including five parts: telencephalon, diencephalon, midbrain, cerebellum, and medulla oblongata. The telencephalon is elongated and elliptical, and is composed of olfactory sacs, olfactory lobes, and cerebral hemispheres. The morphological characteristics of brain tissue include the following aspects: the differentiation of olfactory lobes and olfactory sacs is more obvious, there is a pair of olfactory nerves in front of the olfactory bulb, and the olfactory stem extends from the back to connect with the cerebral hemisphere. interval.
