Neocortical somatostatin neuron diversity in cognition and learning.

Somatostatin-expressing (SST) neurons are a major class of electrophysiologically and morphologically distinct inhibitory cells in the mammalian neocortex. Transcriptomic data suggest that this class can be divided into multiple subtypes that are correlated with morpho-electric properties. At the same time, availability of transgenic tools to identify and record from SST neurons in awake, behaving mice has stimulated insights about their response properties and computational function.

Long-lasting, subtype-specific regulation of somatostatin interneurons during sensory learning.

Somatostatin (SST)-expressing inhibitory neurons are a major class of neocortical γ-amino butyric acid (GABA) neurons, where morphological, electrophysiological, and transcriptomic analyses indicate more than a dozen different subtypes. However, whether this diversity is related to specific roles in cortical computations and plasticity remains unclear. Here we identify learning-dependent, subtype-specific plasticity in layer 2/3 SST neurons of the mouse somatosensory cortex.

Survival rates and extra-regional migration patterns of children and adolescents with cancer in Italy: The 30-year experience of the Italian Association of Pediatric Hematology and Oncology (AIEOP) with the Italian hospital-based registry of pediatric cancer (Mod. 1.01).

Since the 1970s, Italian pediatric oncologists have collaborated through the Italian Association for Pediatric Hematology Oncology (AIEOP) network using a common centralized system for the registration of childhood cancer, known as Model 1.01 (Mod. 1.

HEAR SCORE: A Proposal to Use Only Anamnestic and EKG Data to Evaluate Patients with Very Low Risk Chest Pain.

Purpose: Chest pain in a common symptom in patients attending Emergency Department worldwide and can be related to an extensive variety of disorders, so it represents a diagnostic and logistic challenge for Emergency physicians. The aim of this study is to identify a subgroup of patients with a low pre-test probability of major adverse cardiac events, for which there is no need of troponin testing, to avoid potential harm from false-positive testing and long length stay in ED.

Patients And Methods: We retrospectively analyzed data of patients that attended ED of Siena complaining chest pain from January 2019 to August 2021.

Quantitative Fluorescence Analysis Reveals Dendrite-Specific Thalamocortical Plasticity in L5 Pyramidal Neurons during Learning.

High-throughput anatomic data can stimulate and constrain new hypotheses about how neural circuits change in response to experience. Here, we use fluorescence-based reagents for presynaptic and postsynaptic labeling to monitor changes in thalamocortical synapses onto different compartments of layer 5 (L5) pyramidal (Pyr) neurons in somatosensory (barrel) cortex from mixed-sex mice during whisker-dependent learning (Audette et al., 2019).
