Patterns of variation and allometry in sub-cortical structures of the human brain: an evaluation of sex differences and age
… questions consider if patterns of adult human sub-cortical brain dimorphisms are driven by overall brain size differences between the sexes. Sex differences in absolute brain size in humans are well known. There is a general consensus that male brains are larger in absolute size than female …

Active shape model segmentation of Brain structures in MR images of subjects with fetal alcohol spectrum disorder
… through an assessment of volume and shape of sub-cortical structures on high-resolution MR images.

Statistical shape analysis of neuroanatomical structures based on spherical wavelet transformation
… that morphological changes of neuroanatomical structures may reflect abnormalities in neurodevelopment, or relate to a variety of disorders, such as schizophrenia and Alzheimer's disease (AD). Advances in high-resolution Magnetic Resonance Imaging (MRI) techniques allow us to study these …

Combined fMRI and electrical microstimulation to determine functional connections in visual areas of the primate brain
… modulate visually-driven activity in posterior cortical areas, such as during the deployment of spatial attention. The goals of this thesis were extend the unique aspects of primate fMRI by combining it with simultaneous, intra cortical microstimulation (EM), and to use these new methods to …

Technology development for studying information flow in biological neural networks
… to optically excite up to 5500 neurons in the sub-cortical structures. Moreover, the optrode array can provide both deep brain stimulation and superficial illumination of the brain cortex. Besides, multi-site stimulation could also be achieved by lighting up one or more LED elements. During the …

A cross-species network science approach to childhood adversity
… that early experiences shape the biological substrates of lifelong health and well-being. Indeed, exposure to significant adversity in childhood increases the risk of a range of cognitive and behavioural difficulties later in life. Previous work has sought to understand this pathway by …

NEUROACTIVE AGENTS-MEDIATED CHANGES IN NEURONAL NETWORK ACTIVITY CONTROLS SUSCEPTIBILITY TO SUDDEN UNEXPECTED DEATH IN EPILEPSY (SUDEP)
… neuronal networks mediating S-IRA and the brain structures involved in the fluoxetine-mediated blockade of S-IRA are not known. Data from human SUDEP imaging has underlined the role of periaqueductal gray (PAG), which is also implicated in audiogenic seizure (AGSz) network and respiratory …
