Self-organization of feed-forward structure and entrainment in excitatory neural networks with spike-timing-dependent plasticity.
Spike-timing dependent plasticity (STDP) is an organizing principle of biological neural networks. While synchronous firing of neurons is considered to be an important functional block in the brain, how STDP shapes neural networks possibly toward synchrony is not entirely clear. We examine relations between STDP and synchronous firing in spontaneously firing neural populations. Using coupled he...
متن کاملEnhancing Synchrony with Plasticity
In the previous lab, we explored spike timing-dependent plasticity (STDP) as well as its role in achieving precise timing in a feedforward network. In this lab, we study how STDP compensates for neuronal variations and input noise in a network of recurrently connected neurons. In this prelab, we consider how a recurrent network with STDP synapses and (sinusoidal) global theta inhibition (8.75Hz...
متن کاملInterplay between a phase response curve and spike-timing-dependent plasticity leading to wireless clustering.
A phase response curve (PRC) characterizes the signal transduction between oscillators such as neurons on a fixed network in a minimal manner, while spike-timing-dependent plasiticity (STDP) characterizes the way of rewiring networks in an activity-dependent manner. This paper demonstrates that these two key properties both related to the interaction times of oscillators work synergetically to ...
متن کاملExcitatory and inhibitory STDP jointly tune feedforward neural circuits to selectively propagate correlated spiking activity
Spike-timing-dependent plasticity (STDP) has been well established between excitatory neurons and several computational functions have been proposed in various neural systems. Despite some recent efforts, however, there is a significant lack of functional understanding of inhibitory STDP (iSTDP) and its interplay with excitatory STDP (eSTDP). Here, we demonstrate by analytical and numerical met...
متن کاملSpike-timing-dependent synaptic plasticity can form "zero lag links" for cortical oscillations
We study the impact of spike-timing-dependent synaptic plasticity (STDP) on coherent gamma activity between distant cortical regions with reciprocal projections. Our simulation network consists of two areas and includes a STDP model re4ecting e5cacy suppression between pre/ postsynaptic spike pairs as found in recent experiments during stimulation with spike trains (Nature 416 (2002) 433). We 8...
