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.
Roger Wolcott Sperry pioneered the inception of the chemoaffinity hypothesis following his 1960s experiments on the African clawed frog. [2] He would remove the eye of a frog and reinsert it rotated upside-down—the visual nervous system would eventually repair itself, [3] and the frog would exhibit inverted vision.
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.
A syllabus (/ ˈ s ɪ l ə b ə s /; pl.: syllabuses [1] or syllabi [2]) [3] or specification is a document that communicates information about an academic course or class and defines expectations and responsibilities. It is generally an overview or summary of the curriculum.
Artistic interpretation of the major elements in chemical synaptic transmission. An electrochemical wave called an action potential travels along the axon of a neuron.When the action potential reaches the presynaptic terminal, it provokes the release of a synaptic vesicle, secreting its quanta of neurotransmitter molecules.
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 ...
Synapsins encode neuronal phosphoproteins which associate with the cytoplasmic surface of synaptic vesicles. Family members are characterized by common protein domains, and they are implicated in synaptogenesis and the modulation of neurotransmitter release, suggesting a potential role in several neuropsychiatric diseases.
