Infant cognitive development is the first stage of human cognitive development, in the youngest children. The academic field of infant cognitive development studies of how psychological processes involved in thinking and knowing develop in young children. [ 1 ]
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience. These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
An explorative study found, however, that 3- to 5-month-old infants can be taught independent standing, which was considered safe. [32] Passes objects between hands. [31] Some infantile reflexes, such as the palmar grasp reflex, go away. [31] Grabs objects using a raking grasp, where fingers rake at objects to pick them up. [31]
Defects in neural development can lead to malformations such as holoprosencephaly, and a wide variety of neurological disorders including limb paresis and paralysis, balance and vision disorders, and seizures, [1] and in humans other disorders such as Rett syndrome, Down syndrome and intellectual disability.

The reflex normally integrates by three to four months of age, [12] though it may last up to six months. [13] Bilateral absence of the reflex may be linked to damage to the infant's central nervous system , while a unilateral absence could mean an injury due to birth trauma (e.g., a fractured clavicle or injury to the brachial plexus ).

Cortical white matter increases from childhood (~9 years) to adolescence (~14 years), most notably in the frontal and parietal cortices. [8] Cortical grey matter development peaks at ~12 years of age in the frontal and parietal cortices, and 14–16 years in the temporal lobes (with the superior temporal cortex being last to mature), peaking at about roughly the same age in both sexes ...
As we age, our brain experiences both structural and functional changes. Over time, this can cause a decline in cognitive abilities, memory, and even emotional regulation.
