WebSnapshot 1: example of feedforward inhibition, where the repeated spiking of neuron 2 causes continual inhibition in neuron 3. Snapshot 2: example of feedback inhibition, where spiking activity in neuron 3 leads to later self-inhibition in neuron 3, which in turn allows for excitation again. Snapshot 3: fine-tuning of the synaptic currents may ...

Within the CA3 region of the hippocampus, glutamatergic mossy fiber (MF) synapses onto CA3 pyramidal cells (PCs) provide strong monosynaptic excitation that …

WebOct 10, 2024 · Here, we characterized a feedforward inhibition circuit, through which BLA-evoked activation of NAc shell (NAcSh) MSNs was fine-tuned by GABAergic monosynaptic innervation from adjacent fast-spiking interneurons (FSIs). Specifically, BLA-to-NAcSh projections predominantly innervated NAcSh FSIs compared with MSNs and triggered … WebNational Center for Biotechnology Information

WebAll of these effects are captured by unbalancing the E/I ratio in a feedforward inhibition circuit model. Altogether, our results indicate that activity-dependent modulation of perisomatic inhibitory strength effectively influences the participation of single principal cortical neurons to cognition-relevant network activity. : Lourenço et al ...
