Abstract:
Classification of inhibitory interneurons is critical in determining their role in normal information processing and pathophysiological conditions such as epilepsy. Classification schemes have relied on morphological, physiological, biochemical, and molecular criteria; and clear correlations have been demonstrated between firing patterns and cellular markers such as neuropeptides and calcium-binding proteins. This molecular diversity has allowed generation of transgenic mouse strains in which GFP expression is linked to the expression of one of these markers and presumably a single subtype of

Abstract:
The hippocampus is thought to encode information by altering synaptic strength via synaptic plasticity. Some forms of synaptic plasticity are induced by lipid-based endocannabinoid signaling molecules that act on cannabinoid receptors (CB1). Endocannabinoids modulate synaptic plasticity of hippocampal pyramidal cells and stratum radiatum interneurons; however, the role of endocannabinoids in mediating synaptic plasticity of stratum oriens interneurons is unclear. These feedback inhibitory interneurons exhibit presynaptic long-term potentiation (LTP), but the exact mechanism is not entirely und

Abstract:
GABAergic interneurons are thought to play a critical role in eliciting interictal spikes (IICs) and triggering ictal discharges in temporal lobe epilepsy, yet the contribution of different interneuronal subtypes to seizure initiation is still largely unknown. Here we took advantage of optogenetic techniques combined with patch-clamp and field recordings to selectively stimulate parvalbumin (PV)- or somatostatin (SOM)-positive interneurons expressing channelrhodopsin-2 (CHR-2) in layers II–III of adult mouse medial entorhinal cortical slices during extracellular perfusion with the proconvulsiv

Abstract:
Synchronization of precise spike times across multiple neurons carries information about sensory stimuli. Inhibitory interneurons are suggested to promote this synchronization, but it is unclear whether distinct interneuron subtypes provide different contributions. To test this, we examined single-unit recordings from barrel cortex in vivo and used optogenetics to determine the contribution of parvalbumin (PV)– and somatostatin (SST)–positive interneurons to the synchronization of spike times across cortical layers. We found that PV interneurons preferentially promote the synchronization of sp

Abstract:
AbstractAbnormalities in cortical interneurons are closely associated with neurological diseases. Most patients with Foxg1 syndrome experience seizures, suggesting a possible role of Foxg1 in the cortical interneuron development. Here, by conditional deletion of Foxg1, which was achieved by crossing Foxg1fl/fl with the Gad2-CreER line, we found the postnatal distributions of somatostatin-, calretinin-, and neuropeptide Y-positive interneurons in the cortex were impaired. Further investigations revealed an enhanced dendritic complexity and decreased migration capacity of Foxg1-deficient interne

The hippocampus is commonly divided into two main areas, the dentate gyrus (DG) and cornu ammonis (CA). Cortical information is transferred to the DG, the primary gate of the hippocampus, through perforant paths (PPs) and further relayed to other hippocampal areas. The DG is a well-laminated structure composed of the molecular layer (ML), the granule cell layer (GCL), and hilus (HI). The DG contains heterogenous types of neurons including glutamatergic excitatory principal

The two major types of inhibitory interneuron, Parvalbumin-positive (PV+) and Somatostatin-positive (SST+) interneurons are essential for the information processing and memory formation in the hippocampus. Learning and memory are mediated by the experience-dependent plasticity in the neuronal circuits. However, the molecular mechanism of PV+ and SST+ interneurons during the learning process remained unclear. Here, we utilized enriched environment (EE) as a

In severe, unremitting Tourette syndrome, there are decreases in somatostatin-positive/nitric oxide synthase–positive interneurons, fast spiking parvalbumin-positive/γ-aminobutyric acid-ergic interneurons, as well as tonically active cholinergic interneurons in the caudate nucleus and putamen.
