Functional MRI in Awake Unrestrained Dogs

Because of dogs' prolonged evolution with humans, many of the canine cognitive skills are thought to represent a selection of traits that make dogs particularly sensitive to human cues. But how does the dog mind actually work? To develop a methodology to answer this question, we trained two dogs to remain motionless for the duration required to collect quality fMRI images by using positive rein...

Laminar specificity of functional MRI onset times during somatosensory stimulation in rat.

The blood oxygenation level-dependent (BOLD) response to somatosensory stimulation was measured in alpha-chloralose-anesthetized rats. BOLD fMRI was obtained at 40-ms temporal resolution and spatial resolution of 200 x 200 x 2,000 microm(3) by using a gated activation paradigm in an 11.7 T MRI. Results show a consistent heterogeneity of fMRI onset times and amplitudes. The earliest onset time (...

Detection of Brain Activity during Chronic Pain Using Activity-Induced Manganese-Enhanced MRI in the Ra

【Introduction】 Nerve injury occasionally induces neuropathic pain, which is a type of chronic pain. The cardinal symptom of neuropathic pain is spontaneous or touch-evoked pain. Spontaneous pain is either continuous or paroxysmal. Touch-evoked pain consists of allodynia and hyperalgesia. Allodynia is pain triggered by innocuous stimuli, and hyperalgesia is an exaggerated response to painful sti...

MB-SWIFT functional MRI during deep brain stimulation in rats

Recently introduced 3D radial MRI pulse sequence entitled Multi-Band SWeep Imaging with Fourier Transformation (MB-SWIFT) having virtually zero acquisition delay was used to obtain functional MRI (fMRI) contrast in rat's brain at 9.4 T during deep brain stimulation (DBS). The results demonstrate that MB-SWIFT allows functional images free of susceptibility artifacts, and provides an excellent f...

In vivo visuotopic brain mapping with manganese-enhanced MRI and resting-state functional connectivity MRI

The rodents are an increasingly important model for understanding the mechanisms of development, plasticity, functional specialization and disease in the visual system. However, limited tools have been available for assessing the structural and functional connectivity of the visual brain network globally, in vivo and longitudinally. There are also ongoing debates on whether functional brain con...
