A model view of the synapse. Synaptic pruning, a phase in the development of the nervous system, is the process of synapse elimination that occurs between early childhood and the onset of puberty in many mammals, including humans. [1] Pruning starts near the time of birth and continues into the late-20s. [2]
This "pruning" mechanism removes redundant connections in the brain. Huttenlocher found that in individuals with intellectual disabilities, this mechanism works differently. [2] Huttenlocher also became an early authority on Reye's syndrome, and in 1987 launched the first clinic in the United States for children with tuberous sclerosis. [4]
Perceptual narrowing is a developmental process during which the brain uses environmental experiences to shape perceptual abilities. This process improves the perception of things that people experience often and causes them to experience a decline in the ability to perceive some things to which they are not often exposed.
Pruning is the practice of removing parameters (which may entail removing individual parameters, or parameters in groups such as by neurons) from an existing artificial neural networks. [1] The goal of this process is to maintain accuracy of the network while increasing its efficiency .
According to McKinney, neurotheology sources the basis of religious inquiry in relatively recent developmental neurophysiology. According to McKinney's theory, pre-frontal development, in humans, creates an illusion of chronological time as a fundamental part of normal adult cognition past the age of three.
Siegel's model of the brain attempts to simplify the complexity of brain formation in emphasizing interaction between the brainstem, limbic systems (hippocampus and amygdala) and middle prefrontal cortex. Close proximity between the Limbic System (Hippocampus & Amygdala) and Brainstem. Brainstem: A major role of the brainstem involves regulation.

The triune brain is a model of the evolution of the vertebrate forebrain and behavior, proposed by the American physician and neuroscientist Paul D. MacLean in the 1960s.
