Synaptogenesis is particularly important during an individual's critical period, during which there is a certain degree of synaptic pruning due to competition for neural growth factors by neurons and synapses. Processes that are not used, or inhibited during their critical period will fail to develop normally later on in life.
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.
As synapses form during synaptogenesis, they differentiate into one of two categories: excitatory or inhibitory. Excitatory synapses increase probability of firing an action potential in the postsynaptic neuron and are often glutamatergic , or synapses in which the neurotransmitter glutamate is released.
The mean volume of mitochondria per neuron is 20% greater [18] The volume of glial cell nuclei for each neuron is 63% higher [18] Capillary density is increased. [22] Capillaries are wider (4.35 μm compared to 4.15 μm in controls) [18] Shorter distance exist between any part of the neuropil and a capillary (27.6 μm compared to 34.6 μm) [18]
Educational neuroscience (or neuroeducation, [1] a component of Mind Brain and Education) is an emerging scientific field that brings together researchers in cognitive neuroscience, developmental cognitive neuroscience, educational psychology, educational technology, education theory and other related disciplines to explore the interactions between biological processes and education.
Neurons in culture develop synapses that are similar to those that form in vivo, suggesting that synaptogenic signals can function properly in vitro. CNS synaptogenesis studies have focused mainly on glutamatergic synapses. Imaging experiments show that dendrites are highly dynamic during development and often initiate contact with axons.
Synaptic cell adhesion molecules (CAMs) play a crucial role in axon pathfinding and synaptic establishment between neurons during neurodevelopment and are integral members in many synaptic processes including the correct alignment of pre- and post-synaptic signal transduction pathways, vesicular recycling in regards to endocytosis and exocytosis, integration of postsynaptic receptors and ...
Activity-dependent plasticity is a form of functional and structural neuroplasticity that arises from the use of cognitive functions and personal experience. [1] Hence, it is the biological basis for learning and the formation of new memories.
