      The morphological and synaptic properties of S1 neuronal microcircuits described in this review were to a large extent obtained from in vitro paired recording studies. An example of such a correlated structural-functional analysis is shown in Figure 2 for the intralaminar synaptic connection between two neighbouring L2/3 pyramidal cells. Fig. 1. Schematic representation of the 5 steps of neuronal morphology analysis by SynD. (A) Representative pictures of neuronal culture types that can be analyzed with SynD: single neuron micro-island cultures (A1), single filled or transfected neuron within a neuronal network (A2) and neuronal population (A3).

By using paired recordings of synaptically connected interneurons in slice preparations of the rat and mouse dentate gyrus (DG), we show that morphologically identified interneurons form complex neuronal networks.

    Synaptic plasticity, a change in synaptic strength in response to stim-uli, is an essential feature of neuronal circuits that need to adapt in an experience-dependent manner. 1. The ability to alter synaptic strength in response to different degrees of activation endows circuits with the. Microcircuits in different brain areas share similar architectural and biophysical properties with compact motor networks known as central pattern generators (CPGs). Consequently, CPGs have been suggested as valuable biological models for understanding of microcircuit dynamics and particularly, their synchronization. We use a well known compact motor network, the lobster pyloric CPG to study Cited by:

Previous reports, based on the use of chemical inhibitors, have connected the stress kinase p38α to neuroinflammation, neuronal death and synaptic by:   Traditionally, high level brain processes are explained using the framework illustrated in red in Figure Figure1A 1 A where molecular dynamics at neuronal synapses are linked to system-level brain functions via synaptic neuronal signaling (Kandel et al., ).

Spike train covariance determines synaptic plasticity We begin by reviewing a well studied phenomenological model of spike timing-dependent plasticity (STDP) [49], acting within a simple circuit of two reciprocally coupled Size: 4MB.

Synaptic interactions between nearby excitatory and inhibitory neurons in the neocortex are thought to play fundamental roles in sensory processing.

If the time constants τ E \tau_{E} and τ I \tau_{I} of excitatory and inhibitory synapses are sufficiently short, we may approximate stochastic spike arrivals by white noise. Some synapse types, such as the NMDA component of excitatory synapses, are, however, rather slow (cf.
