This article describes a biological neural network model that can be used to explain how children learn to understand language meanings about the perceptual and affective events that they consciously experience. This kind of learning often occurs when a child interacts with an adult teacher to learn language meanings about events that they experience together. Multiple types of self-organizing brain processes are involved in learning language meanings, including processes that control conscious visual perception, joint attention, object learning and conscious recognition, cognitive working memory, cognitive planning, emotion, cognitive-emotional interactions, volition, and goal-oriented actions.

This study will review the demographics, characteristics and clinical course of patients presenting with features of acute organophosphorus toxicity to a regional Emergency Centre in Johannesburg, South Africa.
Methods: This was a retrospective chart review of all patients treated for possible acute organophosphorus toxicity from January 2020 to August 2021.
A neural network architecture models how humans learn and consciously perform musical lyrics and melodies with variable rhythms and beats, using brain design principles and mechanisms that evolved earlier than human musical capabilities, and that have explained and predicted many kinds of psychological and neurobiological data. One principle is called : Working memories store sequential information in a rate-invariant and speaker-invariant way to avoid using excessive memory and to support learning of language, spatial, and motor skills. Stored invariant representations can be flexibly performed in a rate-dependent and speaker-dependent way under volitional control.

The acceptable NAR has been a debated issue. Previously, a higher rate was accepted, whilst newer thinking favours a lower rate.

Three bat die-offs in National Park Service units were attributed to rabies, highlighting the value of including rabies, and rabies virus strain spillover events, as a differential in mass mortality events.
