Cortical circuit function is regulated by extensively interconnected, diverse populations of GABAergic interneurons that may play key roles in shaping operation according to behavioral context. A specialized population co-express vasoactive intestinal peptides (VIP-INs) are activated during arousal and innervate other INs pyramidal neurons (PNs). Although state-dependent modulation VIP-INs has been studied, their role regulating sensory processing less well understood. We examined the impact primary visual cortex awake behaving mice. Loss VIP-IN activity alters somatostatin-expressing (SST-INs) but not PNs. In contrast, reduced globally disrupts feature selectivity for stimulus size. Moreover, on perceptual behavior varies with context more acute small than large cues. thus contribute both cortical context-dependent performance.

Abstract Calcium imaging with protein-based indicators 1,2 is widely used to follow neural activity in intact nervous systems, but current protein sensors report at timescales much slower than electrical signalling and are limited by trade-offs between sensitivity kinetics. Here we large-scale screening structure-guided mutagenesis develop optimize several fast sensitive GCaMP-type 3–8 . The resulting ‘jGCaMP8’ sensors, based on the calcium-binding calmodulin a fragment of endothelial nitric oxide synthase, have ultra-fast kinetics (half-rise times 2 ms) highest for reported calcium sensor. jGCaMP8 will allow tracking large populations neurons relevant computation.

The role of the prefrontal cortex (PFC) takes center stage among unanswered questions in modern neuroscience. PFC has a Janus-faced nature: it enables sophisticated cognitive and social abilities that reach their maximum expression humans, yet underlies some devastating symptoms psychiatric disorders. Accordingly, appropriate development is crucial for many high-order dysregulation this process been linked to various neuropsychiatric diseases. Reviewing recent advances field, with primary focus on rodents we highlight why, despite differences across species, cross-species approach fruitful strategy understanding development. We briefly review developmental contribution molecules extensively discuss how electrical activity controls early maturation wiring areas, as well emergence refinement input-output circuitry involved processing. Finally, mechanisms dysfunction relevance

Fluorescent calcium indicators are often used to investigate neural dynamics, but the relationship between fluorescence and action potentials (APs) remains unclear. Most APs can be detected when soma almost fills microscope's field of view, image populations neurons, necessitating a large generating fewer photons per neuron, compromising AP detection. Here, we characterized AP-fluorescence transfer function in vivo for 48 layer 2/3 pyramidal neurons primary visual cortex, with simultaneous imaging cell-attached recordings from transgenic mice expressing GCaMP6s or GCaMP6f. While most were under optimal conditions, conditions typical population studies, only minority 1 2 events (often <10% ~20-30%, respectively), emphasizing limits detection more realistic conditions.Neurons, cells that make up nervous system, transmit information using electrical signals known as spikes.

Another study neuronal molecules change how they interact light binds them, since changes concentration indicative spiking. That observed specialized microscopes know two-photon microscopes.

Changes in an animal's behavior and internal state are accompanied by widespread changes activity across its brain. However, how neurons the brain encode this is impacted poorly understood. We recorded brain-wide diverse motor programs of freely moving C. elegans built probabilistic models that explain each neuron encodes quantitative behavioral features. By determining identities neurons, we created atlas defined classes connectome behavior. Many have conjunctive representations multiple behaviors.
