New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

The Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Insulin Modulates Neural Activity of Pyramidal Neurons in the Anterior Piriform Cortex

Frontiers in Cellular Neuroscience, 2017
Insulin is an important peptide hormone that regulates food intake and olfactory function. While a multitude of studies investigated the effect of insulin in the olfactory bulb and olfactory epithelium, research on how it modulates higher olfactory ...

Sniffing Out NMDA Receptors in the Olfactory Cortex [PDF]

Neuron, 2005
Selective olfactory learning is essential for survival in most newborn mammals. Findings by Franks and Isaacson in this issue of Neuron suggest that early olfactory learning might be selective, in part because olfactory experience downregulates NMDA receptors at primary inputs to the olfactory cortex.

Production of 3D printed biomodels of the canine brain for veterinary neuroanatomy teaching

Anatomical Sciences Education, EarlyView.
Abstract Teaching neuroanatomy presents multiple challenges to both students and teachers, as it is a subject with highly dense content that commonly causes the development of aversion by students, a phenomenon referred to as “neurophobia,” which has been documented in human and veterinary medicine students.

Feeding-induced olfactory cortex suppression reduces satiation

Neuron
Binge feeding commonly leads to overeating. Experiencing flavor during food consumption contributes to satiation. Still, the interactions between flavor, binge feeding, and food intake remain unknown. Using miniscopes for in vivo calcium imaging in the anterior piriform cortex (aPC) in freely moving mice, we identified specific excitatory neuronal ...

Altered Brain Structure in an ATRX‐Deficient Mouse Model of Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Mutations in the ATRX gene are a primary cause of alpha‐thalassemia intellectual disability X‐linked (ATRX) syndrome, which is characterized by intellectual disability, autism, and a range of brain structural abnormalities, including microcephaly.

Nanomaterial‐based immune therapeutic strategies in neurodegenerative diseases

BMEMat, EarlyView.
This review highlights the immunomodulatory potential of nanomaterials (NMs) in treating neurodegenerative diseases (NDs). It focuses on their roles in regulating innate and adaptive immune responses to maintain immune homeostasis. By providing insights into these mechanisms, the review lays the groundwork for innovative NMs therapeutic strategies to ...

Sentience in cephalopod molluscs: an updated assessment

Biological Reviews, EarlyView.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Distinct projection patterns of different classes of layer 2 principal neurons in the olfactory cortex

Scientific Reports, 2017
The broadly-distributed, non-topographic projections to and from the olfactory cortex may suggest a flat, non-hierarchical organization in odor information processing.
