Functional Magnetic Resonance Imaging of Pain in the Spinal Cord and Brainstem
(2008-09-26)
Functional magnetic resonance imaging (fMRI) studies performed to date have focused on brain structures rostral to the thalamus, although the first level of sensory information and pain transmission occurs at the spinal ...
The Distribution of Serotoninergic and Noradrenergic Synapses on the Dendritic Trees of Spinal Motoneurons
(2008-10-21)
The currents generated by excitatory and inhibitory synapses on motoneurons can be amplified by noradrenalin and serotonin. Both of these neurotransmitters act, and interact, via the same Gq-protein second-messenger system ...
Balancing Energy Demands with the Potential for Threat in the Environment
(2008-09-19)
In their natural environment animals must balance their safety requirements (i.e., avoiding predation) with their need to satisfy their energy demands (i.e., securing food). How the brain integrates these competing demands ...
Muscles that see: early muscle activations are time-locked to the onset of visual targets
(2007-10-03)
The visual grasp reflex provides automatic orienting of gaze (the visual axis in space) to novel visual stimuli. Previous studies have demonstrated activation of neck muscles of awake monkeys appearing at a short fixed ...
Simultaneous Imaging and Current Clamp Recordings from Hippocampal Slices during Simulated Ischemia
(2008-09-27)
Following sudden failure of the Na+/K+ATPase pump, the acute neuronal swelling and dendritic damage that occurs within minutes of stroke onset are consequences of anoxic depolarization (AD). The AD front in our protocol ...
Representation of object dynamics for action
(2007-09-12)
The human hand has evolved to be remarkably good at skillfully manipulating objects. This manipulation requires knowledge of the dynamic properties of an object, which is represented in the central nervous system (CNS) by ...
Behavioural and Neuroimaging Studies of the Influence of Semantic Context on the Perception of Speech in Noise
(2008-09-19)
Meaningful semantic context has been shown to improve comprehension of spoken sentences by young and old adults, especially in difficult listening conditions. Whether older adults benefit differently than younger adults ...
The Prevalence of Epilepsy and Seizures in Subjects with Fetal Alcohol Spectrum Disorders
(2009-07-23)
The Prevalence of Epilepsy and Seizures in Subjects with Fetal Alcohol Spectrum Disorders. MSc Thesis, Queen’s University, Kingston, Ontario, Canada, May 2009.
OBJECTIVE: Fetal alcohol spectrum disorders (FASD) is the ...
Activation of EPAC Inhibits the Aquisition of Nucleus Accumbens Amphetamine Place Preference in a Dose-Dependent Manner in Rats
(2008-04-28)
Reward-related learning occurs when previously neutral stimuli acquires an enhanced ability to elicit approach and other responses. Studies in the past have shown that dopamine receptor-mediated 3’,5’-cyclic adenosine ...
Sexual Responses in the Human Spinal Cord
(2009-10-07)
Altered sexual function is one of the most devastating consequences of spinal cord trauma (SCT). Despite this fact, current knowledge of the neural circuitry regulating sexual response in the spinal cord (SC) in healthy ...
