Spike-timing-dependent plasticity (STDP) is a biological process that adjusts the strength of connections between neurons in the brain. The process adjusts the connection strengths based on the relative timing of a particular neuron's output and input action potentials (or spikes). The STDP process partially … See more Under the STDP process, if an input spike to a neuron tends, on average, to occur immediately before that neuron's output spike, then that particular input is made somewhat stronger. If an input spike tends, on average, to … See more According to the Hebbian rule, synapses increase their efficiency if the synapse persistently takes part in firing the postsynaptic target neuron. Similarly, the efficiency of … See more The concept of STDP has been shown to be a proven learning algorithm for forward-connected artificial neural networks in pattern recognition. Recognising traffic, sound or movement using Dynamic Vision Sensor (DVS) cameras has been an area of research. Correct … See more In 1973, M. M. Taylor suggested that if synapses were strengthened for which a presynaptic spike occurred just before a postsynaptic spike more often than the reverse (Hebbian … See more Postsynaptic NMDA receptors are highly sensitive to the membrane potential (see coincidence detection in neurobiology). Due to their high … See more For the most efficient STDP, the presynaptic and postsynaptic signal has to be separated by approximately a dozen milliseconds. … See more • Synaptic plasticity • Didactic organisation See more WebOct 16, 2024 · Objective: Here, we test if spike-timing-dependent plasticity (STDP) can explain stimulation-outlasting con-nectivity modulation by dual-site tACS and explore the effects of tACS parameter choices.
