Equine grass sickness : the geochemical connection

A new study uses the British Geological Survey’s geochemical map to investigate whether minerals in the environment are a factor in this predominantly fatal neurodegenerative disease of horse

Equine grass sickness in Scotland: a case-control study of environmental geochemical risk factors

Epidemiological investigations suggest that soil macro- and micro-nutrients may be a trigger for the occurrence of equine grass sickness (EGS). However, there is limited information regarding relationships between exposure to geochemical elements and the occurrence of EGS. Objectives To determine whether the geographical distribution of EGS cases referred to the Royal (Dick) School of Veterinary Studies was associated with the presence or absence of particular geochemical elements in the environment

Can the distribution of cases of equine grass sickness in Scotland be explained by geochemical parameters?

Equine grass sickness (EGS) is a frequently fatal neurological disease, which affects horses grazing fields in certain geographical locations. The aim of this study was to determine whether the geographical distribution of EGS cases referred to the Royal (Dick) School of Veterinary Studies, Edinburgh, Scotland was associated with the presence or absence of particular geochemical parameters in the environment

Auditory-somatosensory multisensory processing in auditory association cortex: an fMRI study.

Using high-field (3 Tesla) functional magnetic resonance imaging (fMRI), we demonstrate that auditory and somatosensory inputs converge in a subregion of human auditory cortex along the superior temporal gyrus. Further, simultaneous stimulation in both sensory modalities resulted in activity exceeding that predicted by summing the responses to the unisensory inputs, thereby showing multisensory integration in this convergence region. Recently, intracranial recordings in macaque monkeys have shown similar auditory-somatosensory convergence in a subregion of auditory cortex directly caudomedial to primary auditory cortex (area CM). The multisensory region identified in the present investigation may be the human homologue of CM. Our finding of auditory-somatosensory convergence in early auditory cortices contributes to mounting evidence for multisensory integration early in the cortical processing hierarchy, in brain regions that were previously assumed to be unisensory
