The human brain is one of the most fascinating and complex organs in the human body. It consists of more than 100 billion neurons and is responsible for every thought, feeling, and action we experience. Understanding the different parts and functions of the human brain is essential in comprehending how we perceive, process, and react to external stimuli.
In this blog post, we will dive deep into the types of brain, the 7 parts of the human brain, its functions, and everything you need to know about the human brain.
Types of Brain
There are three types of brain: the reptilian brain, the limbic brain, and the neocortex brain.
1. Reptilian Brain
The reptilian brain is sometimes referred to as the “primitive” brain because it is the oldest part of the brain. It controls basic life functions like breathing, heartbeat, and body temperature regulation. It’s also responsible for instinctual behaviors like aggression, dominance, and territoriality.
2. Limbic Brain
The limbic brain is responsible for emotions, behavior, and motivation. It consists of several structures, including the hypothalamus, hippocampus, and amygdala. These structures work together to regulate our emotional responses to external stimuli.
3. Neocortex Brain
The neocortex brain is the most “modern” part of the brain. It is responsible for high-level cognitive functions like language, problem-solving, and decision-making. The neocortex also houses the sensory areas responsible for processing our senses like vision, hearing, and touch.
What Are The 7 Parts Of The Human Brain?
- Cerebral cortex
- Thalamus
- Hypothalamus
- Brainstem
- Cerebellum
- Corpus callosum
- Basal ganglia
1. Cerebral Cortex
The cerebral cortex is the outermost layer of the brain and is responsible for high-level cognitive functions like thinking, perception, and language. It is made up of four lobes, each with a specific function.
- Frontal lobe: responsible for decision-making, problem-solving, and planning.
- Parietal lobe: responsible for processing sensations like touch, pressure, and temperature.
- Occipital lobe: responsible for processing visual information.
- Temporal lobe: responsible for processing auditory information and language comprehension.
2. Thalamus
The thalamus is the gateway for all sensory information entering the brain. It relays sensory information to the appropriate areas of the cerebral cortex for processing.
3. Hypothalamus
The hypothalamus is responsible for regulating basic life functions like body temperature, hunger, thirst, and sleep.
4. Brainstem
The brainstem is responsible for regulating our most basic life functions like breathing, heartbeat, and blood pressure.
5. Cerebellum
The cerebellum is responsible for coordinating movement and balance. It receives information from the sensory systems, the spinal cord, and other parts of the brain to manage motor skills.
6. Corpus Callosum
The corpus callosum is a bundle of nerve fibers that connects the two hemispheres of the brain. It allows for communication between the left and right sides of the brain.
7. Basal Ganglia
The basal ganglia are responsible for voluntary motor control and procedural learning. It is composed of several structures, including the striatum, globus pallidus, and substantia nigra.
Functions of the Brain
The human brain has over 10 functions that are critical for our survival. Here are some of the most important functions of the brain.
1. Sensory processing
The brain receives information from our senses and processes it to give us a better understanding of the world around us.
2. Motor control
The brain coordinates muscle movements in response to signals from our senses, allowing us to perform complex tasks like walking and running.
3. Emotional processing
The brain processes our emotions and gives us the ability to feel and express various emotions.
4. Memory
The brain stores and retrieves information from short-term and long-term memory.
5. Language
The brain allows us to communicate with each other through spoken, written, and sign language.
