Week 3: The Beginning of Nervous System Formation
Believe it or not, your baby’s nervous system begins to form just 3 weeks after fertilization. At this point, the embryo consists of only a few cells, but the foundation for the nervous system is already being laid. The neural plate, a flat structure that will eventually become the brain and spinal cord, starts to develop.
Week 4-5: Basic Nervous System Structures Emerge
By week 4, the neural tube has formed from the neural plate, marking the beginning of the central nervous system. At this stage, the brain and spinal cord are still very simple structures. However, by the end of week 5, the basic structures of the brain begin to take shape, including the forebrain, midbrain, and hindbrain.
Week 6-7: The Brain and Spinal Cord Take Shape
At around week 6, the brain starts to divide into different regions, each with its own specific function. The spinal cord also begins to take shape, developing into a long, thin structure that runs from the brain to the tailbone. By week 7, the brain has become more complex, with recognizable structures such as the cerebellum and brainstem.
Week 8-9: The Nervous System Begins to Control Movement
Around week 8, the motor neurons that control movement start to form in the spinal cord. By week 9, the fetus is capable of making small movements, such as flexing its arms and legs. At this stage, the nervous system is still developing rapidly, with an increasing number of connections being made between neurons.
Week 10-14: The Nervous System Continues to Develop
Between weeks 10 and 14, the nervous system continues to develop at a rapid pace. The fetal brain becomes more complex, with the formation of structures such as the corpus callosum, which connects the two hemispheres of the brain. Sensory neurons, which are responsible for gathering information from the environment, also begin to form.
Week 15-20: The Senses Begin to Develop
Around week 15, the fetus begins to develop its senses. The eyes, ears, nose, and tongue start to take shape, and the nervous system begins to process sensory information. By week 20, the fetus is capable of hearing sounds and responding to touch.
Week 21-30: The Nervous System Becomes More Complex
Between weeks 21 and 30, the nervous system becomes even more complex. The cerebral cortex, which is responsible for higher-level thinking and processing, begins to form. The fetus also begins to develop more control over its movements, with the ability to make more purposeful movements such as grasping and kicking.
Week 31-40: The Nervous System Prepares for Birth
As the fetus approaches full term, the nervous system undergoes some final preparations for birth. The lungs start to produce surfactant, a substance that helps the lungs inflate properly after birth. The nervous system also continues to refine its connections and processes, preparing the baby for life outside the womb.
Frequently Asked Questions
Q: What happens if the nervous system doesn’t develop properly?
A: If the nervous system doesn’t develop properly, it can lead to a range of developmental disorders such as cerebral palsy, autism, and epilepsy.
Q: Can I do anything to support my baby’s nervous system development?
A: While the nervous system will develop on its own, there are things you can do to support your baby’s overall development. This includes eating a healthy diet, getting enough prenatal care, and avoiding alcohol and drugs.
Q: When do babies start to show signs of intelligence?
A: Intelligence is a complex trait that is influenced by many factors. However, research suggests that babies can show signs of intelligence as early as 6 months old, such as recognizing familiar faces and responding to their environment.
Q: Can babies feel pain in the womb?
A: While there is still debate among experts, many believe that babies can feel pain in the womb. This is why pain management is often used during fetal surgeries.
Q: When will my baby’s nervous system be fully developed?
A: The nervous system continues to develop throughout childhood and adolescence. However, the basic structures are in place by the time the baby is born.

While the nervous system will develop on its own, there are things you can do to support your baby’s overall development. By eating a healthy diet, getting enough prenatal care, and avoiding alcohol and drugs, you can give your baby the best possible start in life. So, sit back, relax, and enjoy watching your little one’s nervous system develop!
