Compare a mammalian brain to reptilian brain?
Mammalian Brain
The mammalian brain is highly developed and complex, with a large number of neurons and specialized brain regions. The mammalian brain is responsible for a wide range of functions, including:
- Cognition
- Learning and memory
- Emotion
- Movement
- Sensory processing
- Language
The mammalian brain is divided into two hemispheres, which are connected by a bundle of nerve fibers called the corpus callosum. Each hemisphere is responsible for different functions. The left hemisphere is responsible for logical thinking, language, and mathematics. The right hemisphere is responsible for spatial processing, creativity, and music.
Reptilian Brain
The reptilian brain is the oldest part of the brain and is found in all vertebrates. The reptilian brain is responsible for basic survival functions, including:
- Heart rate
- Breathing
- Digestion
- Reproduction
- Fighting or fleeing
The reptilian brain is located at the base of the brain and is made up of three parts:
- The medulla oblongata
- The pons
- The midbrain
The medulla oblongata controls the basic functions of life, such as heart rate and breathing. The pons connects the medulla oblongata to the cerebrum and cerebellum. The midbrain is responsible for eye movement and balance.
Comparison of Mammalian and Reptilian Brains
The mammalian brain is much more complex than the reptilian brain. The mammalian brain has a larger number of neurons and specialized brain regions. The mammalian brain is also responsible for a wider range of functions, including cognition, learning, and memory.
The reptilian brain is responsible for basic survival functions. The reptilian brain is located at the base of the brain and is made up of three parts: the medulla oblongata, the pons, and the midbrain.
Conclusion
The mammalian brain is a complex organ that is responsible for a wide range of functions. The reptilian brain is a more primitive part of the brain that is responsible for basic survival functions.
