In the present work, it was experimentally shown that a neuron in vitro was capable of responding in a manner similar to habituation, Pavlov's reflex and avoidance of the reinforcements. The locality of plastic property modifications and molecular morphology, as well as the connection between functional activity and cytoskeleton have been revealed. A hypothesis is formulated that the neuron is a molecular system which may exercise the control, forecast, recognition, and classification. The basic principles of the molecular mechanisms of the responses underlying integrative activity, learning and memory at the neuronal level are discussed.

One of the most important goals of contemporary biology is to understand the principles of the molecular order underlying the complex dynamic architecture of cells. Here, we present an overview of the main driving forces involved in the cellular molecular complexity and in the emergent functional dynamic structures, spanning from the most basic molecular organization levels to the complex emergent integrative systemic behaviors. First, we address the molecular information processing which is essential in many complex fundamental mechanisms such as the epigenetic memory, alternative splicing, regulation of transcriptional system, and the adequate self-regulatory adaptation to the extracellular environment.

Background: Congenital lung malformations (CLMs) are among the rare anomalies that can be diagnosed by bronchoscopy and imaging. They can cause various respiratory symptoms and complications, especially in children with congenital heart disease. This is an interesting case report of a child with a rare combination of congenital anomalies affecting the airway.

Molecular pathology, such as high-throughput genomic and proteomic profiling, identifies precise disease targets from biopsies but require tissue dissociation, losing valuable histologic and spatial context. Emerging spatial multi-omic technologies now enable multiplexed visualization of genomic, proteomic, and epigenomic targets within a single tissue slice, eliminating the need for labeling multiple adjacent slices. Although early work focused on RNA (spatial transcriptomics), spatial technologies can now concurrently capture DNA, genome accessibility, histone modifications, and proteins with spatially-resolved single-cell resolution.

The establishment of communication circuits requires bringing sources and targets into contact, either directly or indirectly. The Central Nervous System (CNS)'s ability to interpret the environment and generate precise responses depends on the functional efficiency of its neural network, which in turn relies on the 3D spatial organization of its constituents, mainly neurons and glia. Throughout evolution, sensory integration and motor response coordination became linked with the merging of the brain and nerve cord (NC) in the urbilaterian CNS.
