Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

open access: yesThe 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.

Paced-mating increases the number of adult new born cells in the internal cellular (granular) layer of the accessory olfactory bulb. [PDF]

open access: yesPLoS ONE, 2011
The continuous production and addition of new neurons during life in the olfactory bulb is well accepted and has been extensively studied in rodents. This process could allow the animals to adapt to a changing environment.

Glomerular microcircuits in the olfactory bulb [PDF]

open access: yesNeural Networks, 2009
Microcircuits in the olfactory bulb have long received particular attention from both experimentalists and theoreticians, due in part to an abundance of dendrodendritic interactions and other specialized modifications to the canonical cortical circuit architecture.

The carbohydrate CT1 is expressed in topographically fixed glomeruli in the mouse olfactory bulb [PDF]

open access: yes, 2011
Cell surface carbohydrates define subpopulations of primary olfactory neurons whose axons terminate in select glomeruli in the olfactory bulb. The combination of carbohydrates present on axon subpopulations has been proposed to confer a unique identity ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe 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,

Immature olfactory sensory neurons provide behaviourally relevant sensory input to the olfactory bulb

open access: yesNature Communications, 2022
New olfactory sensory neurons (OSNs) wire into highly organized olfactory bulb circuits throughout life. Here, the authors show that immature OSNs provide behaviourally relevant sensory input to olfactory bulb neurons that is functionally distinct from ...

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe 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.

Zebrafish Astroglial Morphology in the Olfactory Bulb Is Altered With Repetitive Peripheral Damage

open access: yesFrontiers in Neuroanatomy, 2020
Zebrafish do not possess the typical astrocytes that are found in mammalian systems. In some brain areas, this teleost has radial glia that appears to perform astrocyte-like functions, but these cells have not been described in the zebrafish olfactory ...

Independent control of gamma and theta activity by distinct interneuron networks in the olfactory bulb

open access: yesNature Neuroscience, 2014
Circuits in the brain possess the ability to orchestrate activities on different timescales, but the manner in which distinct circuits interact to sculpt diverse rhythms remains unresolved. The olfactory bulb is a classic example of a place in which slow

Massive transient damage of the olfactory epithelium associated with infection of sustentacular cells by SARS-CoV-2 in golden Syrian hamsters

open access: yesbioRxiv, 2020
Anosmia is one of the most prevalent symptoms of SARS-CoV-2 infection during the COVID-19 pandemic. However, the cellular mechanism behind the sudden loss of smell has not yet been investigated.
