Collectively, our data demonstrate that visual inputs to the frontal cortex trigger gated feedforward inhibition to initiate goal-directed actions.

feed-forward inhibition in circuit dynamics we here use a model of the locust olfactory system. We found both inhibitory motifs were able to maintain sparse KCs responses and provide optimal odor discrimination. However, we further found that only FB inhibition could create a phase response ...
we used chemogenetic approaches to selectively manipulate these neurons26. To inhibit NPYDRN/vlPAGneurons, a Cre-dependent inhibitory chemogenetic vector, AAV-DIO-hM4Di-eGFP, was injected into the DRN/vlPAG region ofNpyires-Cremice (referred to as NPYhM4Dimice). In vitro electrophysiological r...
The proposed feedforward inhibitory circuit enables the cerebral cortex to disynaptically modulate the rubrospinal control over flexor motor execution. 展开 关键词: Parvalbumin GAD Red nucleus Pararubral area DOI: 10.1007/s00429-002-0250-0
hypophagia and anxiety levels and transmits positive valence. Furthermore, NPYDRN/vlPAGneurons exert differential but synergic anxiolytic effects via inhibitory projections to the paraventricular thalamic nucleus (PVT) and the lateral hypothalamic area (LH). Together, our findings reveal a feedforward ...
where all neurons contribute equally to the global inhibitory signal. The corresponding circuit is shown in Fig. 7d. In contrast, feed-forward inhibition models only modulate their activity depending on the inputs I, such that $$\begin{aligned} \dot{L}_i = - k L_i + I_i - w \sum ...
There are two distinct inhibitory GABAergic circuits in the neostriatum. The feedforward circuit consists of a relatively small population of GABAergic int... JM Tepper,CJ Wilson,T Koós - 《Brain Research Reviews》 被引量: 257发表: 2008年 Neuroimaging Studies of Attention: From Modulation of ...
When the same stimulus is applied near the edge of the receptive field, the afferent response is inhibited by feed forward inhibitory connections in adjacent receptive fields. This process would thereby improve contrast of the stimulus by generating normal activation in afferents whose receptive fields...
In Drosophila, negatively reinforcing dopaminergic neurons also provide the inhibitory control of satiety over appetitive memory expression. Here we show that aversive learning causes a persistent depression of the conditioned odor drive to two downstream feed-forward inhibitory GABAergic interneurons of the...
