Especially, deep learning can extract non-linear network structure, realize approximation of complex function, characterize distributed representation of input data, and demonstrate the powerful ability to learn the essential features of datasets based on a small size of samples Zeng et al.
One supposed dude-dame dimorphism is the width of the corpus callosumthe white matter bridge that connects the brain's left and right hemispheres. There was also no significant sex difference for educational attainment in either subsample and no sex difference by subsample interaction column Sex by Unrelated vs.
After the batch normalization operation, an activation function was used to non-linearize the convolution result. The shape of the convolution kernel was [ d kw kh kc inc out ], where d kw kh k represents the depth, width, and height of the convolution kernel, respectively.
Haber, S. Principles of diffusion tensor imaging and its applications brain sex differences corpus callosum damage in Ramsgate basic neuroscience research.
Behavioral impulsivity paradigms: a comparison in hospitalized adolescents with disruptive behavior disorders. Neuroimage 13 : — But regardless of sex, small brains have a proportionally larger corpus callosumand studies conducted about it are often inconsistent.
Psychiatry Res : — Fiber composition of the human corpus callosum. Why size matters: differences in brain volume account for apparent sex differences in callosal anatomy: the sexual dimorphism of the corpus callosum.
Human Brain Mapping27, White matter Regional volumes VBM: adjusted for total intracranial volume and age The male-female comparison for regional white matter volume revealed no significant sex differences. Experience can alter the brain as much as the brain can regulate experience Paus,
These features are the lowest-level features which may represent the structural features of FA images. Our null hypothesis was rejected in both analyses. Unrelated male-female pairs versus opposite-sex siblings Significant effects of matching for genetic background and shared family environment on sex differences were found only in our VBM gray matter analyses, and most prominently included left and right cerebellar regions.
In our model, the first hidden layer generated 32 feature maps, the second hidden layer produced 64 feature maps, and the third hidden layer yielded feature maps. Cerebral Cortex , 23,
