Do All Animals Have Brains. Other species are marked out by other qualities. Animals with bilateral symmetry (insects, worms, us), however, have collections of neurons grouped together in ganglia, often with an enlarged ganglia in the anterior part of the animal called a brain.
Animals with bilateral symmetry (insects, worms, us), however, have collections of neurons grouped together in ganglia, often with an enlarged ganglia in the anterior part of the animal called a brain. Humans (and other animals) do not have a general capacity in the brain. Do domesticated animals have smaller brains?
Lizards for example have a different sleep cycle of 80 minutes each of their 350 cycles each night.
Lizards for example have a different sleep cycle of 80 minutes each of their 350 cycles each night. All these proteins have been observed in animals, in which they have been shown to have distinct roles in neural function. Do domesticated animals have smaller brains? Neurons may be packed to form structures such as the brain of vertebrates or the neural ganglions of insects.
