Mismatch negativity (MMN) and late discriminative negativity (LDN) were reliably elicited by pitch contour deviants across adulthood (18–86 years). MMN amplitude declined with age and predicted subsequent auditory memory precision, whereas LDN amplitude remained largely stable and showed no relationship with memory performance.

No sex-biased dispersal in a primate with an uncommon social system-cooperative polyandry. [PDF]
An influential hypothesis proposed by Greenwood (1980) suggests that different mating systems result in female and male-biased dispersal, respectively, in birds and mammals.

Membrane channels play an important role in auditory processes. Connexins and pannexins are membrane channels that exist in the cochlea. Connexin26 and connexin30 have been previously shown to be differentially expressed in the developing cochlea of ...

Comparative mortality levels among selected species of captive animals [PDF]
We present life tables by single year of age and sex for groups of animals and for 42 individual mostly mammalian species. Data are derived from the International Species Information System. The survivorship of most of these species has never been mapped

Modelling hippocampal neurogenesis across the lifespan in seven species
The aim of this study was to estimate the number of new cells and neurons added to the dentate gyrus across the lifespan, and to compare the rate of age-associated decline in neurogenesis across species.

Gongylonematiasis in the common marmoset (Callithrix jacchus).
Two cases of gongylonematiasis in common marmosets of two research facilities in Germany are reported. The helminthiasis was transmitted from colony A to colony B by one infected female and within colony B by cockroaches (Blatella germanica). Four of 40 cockroaches examined in colony B were infected with rhabditiform larvae.

Experimental schistosomiasis in the Common Marmoset Callithrix jacchus
In order to evaluate Callithrix jacchus as an animal model for mansoni schistosomiasis, a group of 10 male animals were once percutaneously exposed to 250 cercariae of the Schistosoma mansoni SLM (São Lourenço da Mata) strain.

Impact of diet change on the gut microbiome of common marmosets (Callithrix jacchus)
Gastrointestinal diseases are the most frequently reported clinical problems in captive common marmosets (Callithrix jacchus), often affecting the health and welfare of the animal and ultimately their use as a research subject.

Effects of the mGluR2/3 agonist LY354740 on computerized tasks of attention and working memory in marmoset monkeys [PDF]
Rationale: LY354740 is a recently developed metabotropic glutamatergic receptor 2 and 3 (mGluR2/3) agonist. A high density of mGluR2 has been reported in terminal fields of the perforant path in rodents and humans, suggesting its involvement in cognitive
