, 2014 Axon targeting during the development of the olfactory system is not always accurate and numerous axons over-extend past the target layer into the deeper layers of the olfactory bulb.

The internal crest anatomy of Lambeosaurini (Hadrosauridae: Lambeosaurinae)
The Anatomical Record, EarlyView.Abstract The supracranial crests of lambeosaurine hadrosaurids have long been a focus of study due primarily to their extreme morphology. The external anatomy of lambeosaurine crests is understood to be highly variable between species, but variation in their internal anatomy is less well understood.

, 2007 The formation of precise stereotypic connections in sensory systems is critical for the ability to detect and process signals from the environment. In the olfactory system, olfactory sensory neurons (OSNs) project axons to spatially defined glomeruli ...

The Anatomical Record, EarlyView.Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
The Anatomical Record, EarlyView.Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Regeneration and Rewiring the Olfactory Bulb [PDF]
Chemical Senses, 2005 During olfactory development axons from the sensory epithelium migrate to the olfactory bulb and gradually establish connections with targeted glomeruli (Key and St John, 2002). The spatial distribution of these connections form the basis of a topographical mapping of odorant receptors onto the olfactory bulb (Vassar et al., 1994).

The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

High-fat diet triggers transcriptomic changes in the olfactory bulb
HeliyonMetabolic imbalance contributes to cognitive impairment, anxiety, depressive behavior, and impaired olfactory perception. Recent studies have focused on olfactory dysfunction in patients with obesity and diabetes accompanied by cognitive dysfunction ...
