Loss of neurons from laminas I-III of the spinal dorsal horn is not required for development of tactile allodynia in the spared nerve injury model of neuropathic pain [PDF]

open access: yes, 2005
It has been proposed that death of inhibitory interneurons in the dorsal horn contributes to the neuropathic pain that follows partial nerve injury. In this study, we have used two approaches to test whether there is neuronal death in the dorsal horn in ...

Sex Differences in Associations of Lewy Body Disease with Alzheimer's Disease and Cognitive Decline

open access: yesAnnals of Neurology, EarlyView.
Objective To investigate how sex and age at menopause influence the interplay between Alzheimer's disease (AD) and Lewy body disease (LBD) neuropathologies, and their associations with cognitive decline. Methods We analyzed data from: (1) three Rush Alzheimer's Disease Center cohorts (i.e., the Religious Orders Study, Rush Memory and Aging Project, and

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]

open access: yes, 2006
Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.

Modeling Olfactory Bulb Evolution through Primate Phylogeny

open access: yesPLoS ONE, 2014
Adaptive characterizations of primates have usually included a reduction in olfactory sensitivity. However, this inference of derivation and directionality assumes an ancestral state of olfaction, usually by comparison to a group of extant non-primate ...

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Lineage does not regulate the connectivity of projection neurons in the mouse olfactory bulb [PDF]

open access: yes, 2019
Lineage regulates the synaptic connections between neurons in some regions of the invertebrate nervous system. In mammals recent experiments suggest that cell lineage determines the connectivity of pyramidal neurons in the neocortex, but the functional ...

The endocranial morphology and inner ear of the abelisaurid theropod Aucasaurus garridoi [PDF]

open access: yes, 2015
A partial cranial endocast and right inner ear of the Cretaceous abelisaurid dinosaur Aucasaurus garridoi were digitally reconstructed from CT scans.

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

open access: yesThe Anatomical Record, EarlyView.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...

Computational Models of Adult Neurogenesis

open access: yes, 2004
Experimental results in recent years have shown that adult neurogenesis is a significant phenomenon in the mammalian brain. Little is known, however, about the functional role played by the generation and destruction of neurons in the context of and ...

Gonadal hormones, but not sex, affect the acquisition and maintenance of a Go/No-Go odor discrimination task in mice [PDF]

open access: yes, 2018
In mice, olfaction is crucial for identifying social odors (pheromones) that signal the presence of suitable mates. We used a custom-built olfactometer and a thirst-motivated olfactory discrimination Go/No-Go (GNG) task to ask whether discrimination of ...
