P19: Long-Term Potentiation
The term synaptic plasticity points to a series of persistent changes related to the activity of synapses. Long-term potentiation (LTP) is a reflection of synaptic plasticity that has an important role in learning and memory. LTP is a long-lasting increase of synaptic activity due to enhancement of excitatory synaptic transmission after a high-frequency train of electrical stimulations. Differe...
متن کاملQuantal mechanism of long-term synaptic potentiation.
Intracellular recordings were used to demonstrate the occurrence and to analyze the microphysiology of long-term synaptic potentiation (LTP) in the crayfish opener neuromuscular synapse. Brief stimulation of the single excitor motor axon enhanced the amplitudes of subsequent postsynaptic potentials for several hours. Three methods of quantal analysis were used to evaluate the mechanism responsi...
متن کاملShort-term synaptic enhancement and long-term potentiation in neocortex.
Repetitive stimuli reliably induce long-term potentiation (LTP) of synapses in the upper layers of the granular somatosensory cortex but not the agranular motor cortex of rats. Herein we examine, in these same cortical areas, short-term changes in synaptic strength that occur during the LTP induction period. theta-Burst stimulation produced a strong short-term enhancement of synapses in the gra...
متن کاملP18: Signaling Pathway in Long-Term Potentiation
Synaptic plasticity in the central nervous system (CNS) of mammals has been discussed for many years. Several forms of synaptic plasticity of mammal’s CNS have been identified, such as those that occur in long-term potentiation (LTP). Different types of LTP have been observed in distinctive areas of the CNS of mammals. The hippocampus is one of the most important areas in the CNS that pla...
متن کاملP13: Potassium Channels and Long-Term Potentiation Formation
Long-term potentiation (LTP) is a form of activity-dependent plasticity that occurs during learning. Potassium channels are the most diverse group of all ion channels that related to synaptic plasticity. Small-conductance calcium-activated potassium channels (SKs) are found in hippocampal CA1 neurons and by inhibiting of postsynaptic potentials are involved in synaptic transmission impairment. ...
