Somatostatin-expressing interneurons of the rodent dentate gyrus fall into at least two functionally distinct interneuron types with different synaptic integrations into the local dentate gyrus and the more distant medial septum neuronal network.
Subtypes of dendrite-targeting somatostatin cells segregate into separate networks by specifically connecting with neurons in different layers, forming circuits that could independently control different input pathways to the neocortex.
The cyclic neuropeptide somatostatin binds to human Aβ1-42 through an interface that critically relies on a specific tryptophan, thereby blocking the propensity of Aβ to aggregate, a critical step in the pathobiology of Alzheimer's disease.
Presynaptic GABAB receptors are highly expressed and strongly suppress synaptic transmission at the input and output of hippocampal somatostatin interneurons.
A neural circuit between layer 2/3 pyramidal cells and somatostatin-expressing inhibitory neurons synchronizes spatially separated regions of the visual cortex to gamma rhythms.
The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.
Two major subtypes of cortical interneurons, the PV and the SST positive cells, causally contribute to the regulation of large-scale state transitions in the cortex.
Our work demonstrated that eye opening differentially modulates inhibitory synaptic transmission from Sst-INs and FS-INs to excitatory neurons in the mammalian cortex.
Highly paralleled functional evaluation of enhancer activity in single cells generates new cell-type-specific tools with broad medical and scientific applications.
