Early Detection of Neuroinflammation and White Matter Damage Following Dorsal Spinal Nerve Root Sectioning in a Nonhuman Primate Model

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Dorsal rhizotomy, or spinal dorsal nerve root lesioning, is a surgical procedure used to treat intractable nerve pain by selectively severing sensory afferent nerve roots. This study aimed to evaluate whether multiparametric MRI, including diffusion tensor imaging (DTI), quantitative magnetization transfer (qMT), chemical exchange ...

A perspective on color vision in platyrrhine monkeys [PDF]

open access: yes, 1960
Studies carried out over the past two decades show that many platyrrhine (New World) monkeys have polymorphic color vision. This condition results from the sorting of allelic versions of X-chromosome cone opsin genes at a single gene site, yielding a ...

Partner Choice and Context‐Dependent Sex Differences in Rat Rough‐and‐Tumble Play

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 3, February 2026.
When given partner choice in triadic play, male rats showed a robust preference for female partners, whereas females formed partner preferences that were not sex specific. Females initiated less play in mixed‐sex groups but played at male‐typical levels in all‐female groups, demonstrating that sex differences in rough‐and‐tumble play arise both from ...

Advances in the design and development of oncolytic measles viruses. [PDF]

open access: yes, 2015
A successful oncolytic virus is one that selectively propagates and destroys cancerous tissue without causing excessive damage to the normal surrounding tissue. Oncolytic measles virus (MV) is one such virus that exhibits this characteristic and thus has

Cicada as a food for mammals: a global review and implications for mammal behaviour and populations

open access: yesWildlife Biology, Volume 2026, Issue 1, January 2026.
Cicadas (Hemiptera: Cicadidae) are among the most important insect prey for many vertebrate predators, including birds and mammals, owing to their large size and high nutritional value. Although the ecological roles of cicadas as prey for birds have been well documented, the interactions between mammals and cicadas are relatively unknown.
