Abstract: This unique volume is a comprehensive, well-illustrated study of the organization of the white matter pathways of the brain. Schmahmann and Pandya have analyzed and synthesized the corticocortical and corticosubcortical connections of the major areas of the cerebral cortex of the rhesus monkey. The result is a detailed understanding of the constituents of the cerebral white matter and the organization of the fiber tracts. The findings from the 36 cases studied are presented on a single template brain, facilitating comparison of the locations of the different fiber pathways. The summary diagrams provide a comprehensive atlas of the cerebral white matter. The text is enriched by close attention to functional aspects of the anatomical observations. The clinical relevance of the pathways is addressed throughout the text and a chapter is devoted to human white matter diseases. The introductory account gives a detailed historical background. Translations of seminal original observations by early investigators are presented, and when these are considered in the light of the authors' new observations, many longstanding conflicts and debates are resolved. This scholarly book is an important addition to systems and cognitive neuroscience that will be of lasting value to neurobiologists, anatomists, neurologists, neurosurgeons, neuroradiologists, psychiatrists, psychologists, and to their students and trainees.

Visualizing crossing probabilistic tracts
Mathias Goldau,Andre Reichenbach,Mario Hlawitschka +2 more
- 25 Oct 2015
TL;DR: This work suggests a visualization based on Fiber-Stippling but sensible to multiple diffusion orientations from HARDI-based diffusion models, which implies that tract crossings may now be visualized as crossing stipples, which is an essential step towards an accurate visualization of the neuroanatomy.

TL;DR: This study explores using machine learning to estimate aphasia severity through discourse analysis, finding that discourse-based models outperform lesion-based models and can accurately predict Western Aphasia Battery-Revised scores with minimal resource requirements.

Prediction correction tractography through statistical tracking
Davide Imperati,Iuri Frosio,Marc Tittgemeyer,Nunzio Alberto Borghese +3 more
- 01 Oct 2008
TL;DR: In this paper, a prediction-correction diffusion-based tractography (PDT) method is proposed, which is based on Extended Kalman Filtering (EKF) to estimate the local fibers orientation from their orientation in the previous step, and then corrected from an estimate of the local diffusivity through a principled model of fibers orientation.

Changes in ipsilesional hand motor function differ after unilateral injury to frontal versus frontoparietal cortices in Macaca mulatta
Warren G. Darling,Marc A. Pizzimenti,Diane L. Rotella,Jizhi Ge,Kimberly S. Stilwell-Morecraft,Robert J. Morecraft +5 more
TL;DR: Poorer and slower post-lesion improvement of ipsilesional upper limb motor skill in the F2P2 cases may be due to impaired somatosensory processing, while the persistent ipsileionalupper limb motor deficits frequently observed in humans after stroke are probably caused by greater subcortical white and gray matter damage.

Loss of recent memory after bilateral hippocampal lesions.
TL;DR: The results of these studies point to the importance of the hippocampal complex for normal memory function in patients who had undergone similar, but less radical, bilateral medial temporallobe resections, and as a warning to others of the risk to memory involved in bilateral surgical lesions of the hippocampusal region.

TL;DR: It is concluded that the anterior hippocampus and hippocampal gyrus, either separately or together, are critically concerned in the retention of current experience.

TL;DR: In the monkey premotor cortex there are neurons that discharge both when the monkey performs an action and when he observes a similar action made by another monkey or by the experimenter as mentioned in this paper.
A proposed mechanism of emotion
TL;DR: The following discussion presents some anatomic, clinical and experimental data dealing with the hypothalamus, the gyrus cinguli, the hippocampus and their interconnections, which are proposed as representing theoretically the anatomic basis of the emotions.
