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]
Synaptogenesis is the formation of synapses between neurons in the nervous system.Although it occurs throughout a healthy person's lifespan, an explosion of synapse formation occurs during early brain development, known as exuberant synaptogenesis. [1]
Early life stress is believed to produce changes in brain development by interfering with neurogenesis, synaptic production, and pruning of synapses and receptors. [58] Interference with these processes could result in increased or decreased brain region volumes, potentially explaining the findings that early life stress is associated with ...
The links between nerve cells, called synapses, allow us to learn and adapt, and hold clues to conditions such as autism, schizophrenia and more Making and breaking connections in the brain Skip ...
Much like neuroplasticity, or brain plasticity, developmental plasticity is specific to the change in neurons and synaptic connections as a consequence of developmental processes. A child creates most of these connections from birth to early childhood.
Activity-dependent mechanisms influence neural circuit development and are crucial for laying out early connectivity maps and the continued refinement of synapses which occurs during development. [42] There are two distinct types of neural activity we observe in developing circuits -early spontaneous activity and sensory-evoked activity.
Since memories are postulated to be represented by vastly interconnected neural circuits in the brain, synaptic plasticity is one of the important neurochemical foundations of learning and memory (see Hebbian theory). Plastic change often results from the alteration of the number of neurotransmitter receptors located on a synapse. [2]
Early childhood is characterised by rapid growth in the number of synapses in the brain (synaptogenesis), and this expansion is followed by a pruning period. There are so called experience dependant critical periods during which the developing brain is best suited to develop certain sensory and motor skills.
