In a new study published in The Quarterly Review of Biology, Dr. Karen Hardy and her team bring together archaeological, anthropological, genetic, physiological and anatomical data to argue that carbohydrate consumption, particularly in the form of starch, was critical for the accelerated expansion of the human brain over the last million years, and coevolved both with copy number variation of the salivary amylase genes and controlled fire use for cooking.

Anatomical studies confirmed the importance of the right rehabilitation schedule: Depending on the therapeutic design, different patterns of new nerve fibers that sprouted into the cervical spinal cord from the healthy part of the brain and thus aid functional recovery to varying degrees were apparent.

Such changes, Li and colleagues suggested while reviewing a number of related studies, are consistent with anatomical changes that can occur in the brain as a result of learning a second language, no matter the age of the learner, as they reported in a recent issue of Cortex.

They don't seem to take account of studies outside the anatomical field that examine the function of the vagus nerve, the role of the brain in orgasm, or how direct cervical stimulation can lead to orgasm in paralysed women.

Through analysis of high - resolution anatomical magnetic resonance imaging of brain volumes, taken three times over the two - year study period, the researchers were able to determine that individuals with MCI or Alzheimer's showed greater losses in gray matter volume in both the basal forebrain and temporal lobe, compared with cognitively normal controls.

Scientists not involved in the study noted that not only is it the first to demonstrate widespread anatomical changes in the pregnant human brain, but that it goes further by showing that the changes last for at least 2 years.

This particular brain, which has been so thoroughly studied in the behavioral domain, may still have some anatomical surprises in store.

Scientists had done a few anatomical studies on the autistic brain, but the results were ambiguous.

«Our finding of a link between bipolar disorder and the striatum at the molecular level complements studies that implicate the same brain region in bipolar disorder at the anatomical level, including functional imaging studies that show altered activity in the striatum of bipolar subjects during tasks that involve balancing reward and risk,» said TRSI Research Associate Rodrigo Pacifico, who was first author of the new study.

While those studies uncovered widespread functional and anatomical brain abnormalities in ASD, the results were not highly consistent, possibly reflecting the complex brain pathology in autism spectrum disorders.

Despite dolphins» obvious intelligence and social aptitude, anatomical studies of their gray matter revealed an indistinct muddle of neurons, nothing like the specialized, refined structures found in human brains.

But until this study, no precise anatomical location for this integration of the brain's reward and arousal systems has been pinpointed, said Luis de Lecea, PhD, professor of psychiatry and behavioral sciences.

A team of psychologists and imaging scientists at Vanderbilt has collaborated on a study that provides important corroboration of the validity of these studies by examining the relationship of the fMRI maps of resting state brain's networks with the brain's underlying anatomical and neurological structure.

«Previous studies have suggested that resting state connectivity shown in brain scans is anchored by anatomical connectivity,» said co-senior author Anna Roe, professor of psychology.

Thanks to the efforts of the HBTRC, dedicated investigators and the generosity of a growing number of brain donors and their families, genetic, molecular, and anatomical findings from these studies are paving the way for a better understanding of these disorders and of the people that suffers from them and are providing impetus for the development of new treatments.

By developing computational models that are constrained by experimental evidence (neuroimaging, single - cell recording, anatomical, lesion studies), we can generate hypothesis about how brain networks orchestrate behavior.

Similarly, studies of intrinsic connectivity (resting state) explore functional networks that are non-stimulus driven and may inform about the basic functional brain architecture while implicating anatomical connectivity of the regions involved [153].
