Many scientists try to use the Schaffer collateral synapse as a sample synapse, a typical excitatory glutamatergic synapse in the cortex that has very well been studied in order to try to identify the rules of both the patterns of stimulation in electrical rules and the chemical mechanisms by which synapses get persistently stronger and which ...
For example, in certain neurodegenerative conditions, such as Alzheimer's disease, abnormal sprouting of neurons may contribute to the spread of the disease and further neuronal death. Therefore, while neural sprouting is an important form of neuroplasticity , it is a complex process that can have both positive and negative effects, depending ...
Established collateral branches, like the main axon, exhibit a growth cone and develop independently of the main axon tip. Overall, axon elongation is the product of a process known as tip growth. In this process, new material is added at the growth cone while the remainder of the axonal cytoskeleton remains stationary.
Axon terminals (also called terminal boutons, synaptic boutons, end-feet, or presynaptic terminals) are distal terminations of the branches of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell that conducts electrical impulses called action potentials away from the neuron's cell body to transmit those ...
Neuromorphology (from Greek νεῦρον, neuron, "nerve"; μορφή, morphé, "form"; -λογία, -logia, “study of” [1] [2]) is the study of nervous system form, shape, and structure. The study involves looking at a particular part of the nervous system from a molecular and cellular level and connecting it to a physiological and ...
Molecular neuroscience is a branch of neuroscience that examines the biology of the nervous system with molecular biology, molecular genetics, protein chemistry and related methodologies (ie. concerning neurotransmitters moving via physiology of synapses etc) Neurochemistry; Nutritional neuroscience; Neuropeptide [ also see Neuropharmacology above]
In a synapse, the neuron that sends the signal is the presynaptic neuron and the target cell receives that signal is the postsynaptic neuron or cell. Synapses can be either electrical or chemical. Electrical synapses are characterized by the formation of gap junctions that allow ions and other organic compound to instantaneously pass from one ...
A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.They are located in the brain and spinal cord and help to receive and conduct impulses.
