Human Nervous System (Part 2) - How the Brain Works! (Animation)
Thomas Schwenke・2 minutes read
The brain develops folds during pregnancy to accommodate a high number of neurons; it is divided into parts like the cerebellum and cerebrum with distinct functions in personality, language, and sensory processing, allowing for communication between brain hemispheres. Nerve cells in the brain consist of white matter fibers and gray matter cell bodies, forming synapses to transmit electrical signals to different areas of the brain.
Insights
- The brain undergoes significant development during pregnancy, starting as a smooth structure and later forming folds to accommodate a high number of neurons in a compact space.
- Different regions of the brain, such as the prefrontal cortex, Broca's area, and thalamus, have specialized functions related to personality, language, and sensory processing, emphasizing the complexity and specialization of brain structures in regulating various aspects of human cognition and behavior.

Recent questions
How does the brain develop during pregnancy?
The brain develops in the womb without folds initially, later developing folds to accommodate a high number of neurons in a small space.
What are the main parts of the brain?
The brain is divided into parts including the brain stem, cerebellum, cerebrum with left and right hemispheres, and various lobes.
How is the brain protected?
The brain is protected by the skull, three meninges, and cerebrospinal fluid that acts as a cushion and circulates in ventricles.
What are nerve cells in the brain composed of?
Nerve cells in the brain consist of white matter fibers and gray matter cell bodies that form synapses to transmit electrical signals.
What are the functions of specific brain areas?
Specific areas of the brain like the prefrontal cortex, Broca's area, thalamus, and corpus callosum have distinct functions in personality, language, sensory processing, and facilitating communication between brain hemispheres.
