Unlike other species, humans are born with "half-baked" brains that wire themselves based on the culture, language, and knowledge accumulated by all previous generations. This cumulative learning, not just individual experience, is the key to our rapid advancement as a species.

The cortex has a uniform six-layer structure and algorithm throughout. Whether it becomes visual or auditory cortex depends entirely on the sensory information plugged into it, demonstrating its remarkable flexibility and general-purpose nature, much like a universal computer chip.

Unlike other mammals, human infants are born with significant fat stores. This fat provides essential nutrients like DHA and a source for ketones, which are the preferred fuel for the developing brain, especially in the first few weeks of life.

Scientific evidence suggests that a mother's feelings toward her fetus can imprint a core sense of self before birth. This is demonstrated by a case where a newborn rejected its mother's milk because the mother secretly had not wanted the child.

Animal studies show that offspring of mothers who exercised during pregnancy solved mazes twice as fast and had lower anxiety. The likely mechanism is an increase in the BDNF molecule, which enhances neuroplasticity in both the mother and the developing baby.

The brain circuits for play are not pruned after childhood; they persist because they are vital for adult adaptation. Biology doesn't waste resources. The continued existence of these circuits is proof that play is a fundamental, non-negotiable mechanism for learning and creativity throughout our entire lives.

Diet during pregnancy doesn't just build a baby; it actively programs their DNA by placing epigenetic "switches" on genes. These switches influence the baby's future risk for diseases like diabetes, obesity, and even psychiatric disorders, shaping their health for life.

It's a myth that all cells are a 50/50 blend of parental DNA. Neuroscientist Catherine Dulac's work shows that entire brain areas can be genetically identical to either the mother or the father. This explains why certain behaviors and traits are so strongly inherited from one parent.

There's a qualitative difference between neurons grown in vitro from stem cells and those found in an adult brain. The scientific community discusses whether lab-grown neurons are less mature, like "infant" neurons, and may lack some receptors. The "perfect" neuron for computation is an open research question.
