Human vs Animal Brain with some similarities

Humans are considered to be the most intelligent living organisms on earth. Human beings have the ability to think and react to situations, while animals do not. The human brain is considered large compared to the animal brain. Let’s look at the important difference between the human brain and the animal brain. Human vs Animal Brain with some similarities

Human brain vs animal brain Human vs Animal Brain with some similarities

Below are the main and most important differences between the human brain and the animal brain:

Smell  Human vs Animal Brain with some similarities

The olfactory bulb of humans is smaller compared to animals. Two rodents, the capybara and the agouti, have the largest olfactory bulbs of all mammals. The olfactory bulbs of bears are five times larger than humans.


The pigeon’s brain has specialized cells that can respond to magnetic stimuli. They can detect your geographical position by detecting changes in the Earth’s magnetic field.

Photographic memory 

Children can memorize a lot of information thanks to photographic memory. Chimpanzees have the same quality. Compared to humans, young chimps have a better ability to memorize number sequences.

Brain size

The brain size of most animals is smaller than that of humans (1.2 kg). But there are still several animals that have a larger brain size than humans. These include dolphins (1.5-1.7 kg), elephants and blue whales (5 kg), orcas (6 kg).

Glía s

The glia are the support cells of neurons. The glia to neuron ratio is the indicator of intellectual ability. The glia to neuron ratio of a Minke whale is 5.5 times that of humans. Some animals have a smaller glia / neuron ratio.


Neurogenesis is the process of replacing damaged or lost neurons. Teleost fish perform neurogenesis at a rate 100 times higher than mammals. In mammals, neurogenesis occurs at a specific rate during development. Subsequently, the process is restricted to the areas of the brain responsible for smell and memory.

What is the human brain?

The human brain is the part of the central nervous system located inside the skull. It controls and coordinates all the functions of the body. It’s divided in:

  • Brain
  • Cerebellum
  • Brainstem

The brain is the largest part of the human brain with two cerebral hemispheres. The brain stem connects the brain with the spinal cord. It is made up of the medulla oblongata, pons, and midbrain.

What is the animal brain?

The animal brain is also found in the central nervous system. It is of three types:

  • Invertebrate brain
  • Vertebrate brain
  • Mammal brain

The most complex invertebrate brain is found in arthropods, comprising twin parallel nerve cords that run through the body.

To vertebrates; The brain is made up of a forebrain, a midbrain, and a rhombencephalon.

Similarities between human and animal brain

Similarities between the human brain and the animal brain include:

  1. The human and animal brain are part of the central nervous system.
  2. Their brains are made up of neurons and glia.
  3. Its main function is to control thoughts and body movement.
  4. The brain of all vertebrate animals is divided into forebrain, midbrain, cerebellum, hindbrain, medulla oblongata, and pons.
