Open AccessMale blue wildebeest increase activity during the rut, but not at the expense of rest
Rest is a state of adaptive inactivity that increases the efficiency of activity by regulating its timing and reducing energy use when activity is not beneficial. Thus, animals can go without rest when specifi...

Open AccessA map of white matter tracts in a lesser ape, the lar gibbon
The recent development of methods for constructing directly comparable white matter atlases in primate brains from diffusion MRI allows us to probe specializations unique to humans, great apes, and other prima...

Open AccessExamination of head versus body heading may help clarify the extent to which animal movement pathways are structured by environmental cues?
Understanding the processes that determine how animals allocate time to space is a major challenge, although it is acknowledged that summed animal movement pathways over time must define space-time use. The cr...

Open AccessAmplification of potential thermogenetic mechanisms in cetacean brains compared to artiodactyl brains
To elucidate factors underlying the evolution of large brains in cetaceans, we examined 16 brains from 14 cetartiodactyl species, with immunohistochemical techniques, for evidence of non-shivering thermogenesi...

A three-dimensional digital atlas of the Nile crocodile (Crocodylus niloticus) forebrain
The phylogenetic position of crocodilians in relation to birds and mammals makes them an interesting animal model for investigating the evolution of the nervous system in amniote vertebrates. A few neuroanatom...

Multimodal MRI Template Creation in the Ring-Tailed Lemur and Rhesus Macaque
We present a multimodal registration algorithm for simultaneous alignment of datasets with both scalar and tensor MRI images. We employ a volumetric, cubic B-spline parametrised transformation model. Regularis...

Open AccessLocally-curved geometry generates bending cracks in the African elephant skin
An intricate network of crevices adorns the skin surface of the African bush elephant, Loxodonta africana. These micrometre-wide channels enhance the effectiveness of thermal regulation (by water retention) as we...

Hippocampal neurogenesis in the C57BL/6J mice at early adulthood following prenatal alcohol exposure
We examined the effect of chronic prenatal alcohol exposure (PAE) on the process of adult neurogenesis in C57BL/6J mice at early adulthood (PND 56). Pregnant mice, and their in utero litters, were exposed to a...

Nuclear organization of the African elephant (Loxodonta africana) amygdaloid complex: an unusual mammalian amygdala
Here we describe the nuclear organization of the African elephant amygdaloid complex using Nissl, myelin, and a range of immunohistochemical stains. The African elephant is thought to exhibit many affect-laden...

Nuclear organization of the rock hyrax (Procavia capensis) amygdaloid complex
The current study details the nuclear organization of the rock hyrax amygdaloid complex using both Nissl and myelin stains, along with a range of immunohistochemical stains. The rock hyrax appears to be the le...

Physiological implications of the abnormal absence of the parietal foramen in a late Permian cynodont (Therapsida)
The third eye (pineal eye), an organ responsible for regulating exposure to sunlight in extant ectotherms, is located in an opening on the dorsal surface of the skull, the parietal foramen. The parietal forame...

The neocortex of cetartiodactyls. II. Neuronal morphology of the visual and motor cortices in the giraffe (Giraffa camelopardalis)
The present quantitative study extends our investigation of cetartiodactyls by exploring the neuronal morphology in the giraffe (Giraffa camelopardalis) neocortex. Here, we investigate giraffe primary visual and ...

In contrast to many other mammals, cetaceans have relatively small hippocampi that appear to lack adult neurogenesis
The hippocampus is essential for the formation and retrieval of memories and is a crucial neural structure sub-serving complex cognition. Adult hippocampal neurogenesis, the birth, migration and integration of...

Organization and chemical neuroanatomy of the African elephant (Loxodonta africana) hippocampus
Elephants are thought to possess excellent long-term spatial–temporal and social memory, both memory types being at least in part hippocampus dependent. Although the hippocampus has been extensively studied in...

Organisation and chemical neuroanatomy of the African elephant (Loxodonta africana) olfactory bulb
The olfactory system of mammals can be divided into a main and accessory olfactory system with initial processing for each system occurring in the olfactory bulb. The main and accessory olfactory bulbs have si...

Neuronal morphology in the African elephant (Loxodonta africana) neocortex
Virtually nothing is known about the morphology of cortical neurons in the elephant. To this end, the current study provides the first documentation of neuronal morphology in frontal and occipital regions of t...
