Autism Brain SPECT scan Part I-This video presents the use of Brain SPECT imaging to analyze the blood flow (i.e. related to metabolism) of the cerebral cortex in autism. The video is in two parts. Part I is about the experience of doing a SPECT brain imaging with a child with autism and one of his parents. Part II will explain a little more about what is known regarding the functions of cerebral cortex, and the results obtained from this analysis.
The Human Brain Explore the three interconnected layers of the human brain. The central core (basic life processes), limbic system (emotion and memory) and the cerebral cortex (higher cognitive functions).
Lateral view of the cerebral cortex showing the principal gyri and sulci. Major structures include the central sulcus and the precentral (primary motor), premotor, and postcentral (primary somatosensory) gyri. Also note the gyri situated rostral to the premotor cortex, including the orbital gyri, which mediate higher order intellectual functions and contribute to the regulation of emotional behavior. Brocas motor speech area and Wernickes area (for reception of speech) are important areas…
New insights into how the mind influences the body
Neuroscientists have identified the neural networks that connect the cerebral cortex to the adrenal medulla, which is responsible for the body's rapid response in stressful situations. These findings provide evidence for the neural basis of a mind-body connection. Specifically, the findings shed new light on how stress, depression and other mental states can alter organ function, and show that there is a real anatomical basis for psychosomatic illness.
A new wrinkle: Geometry of brain's outer surface correlates with genetic heritage: Patterns in sulci and gyri don't predict cognitive ability, but may help diagnose disease
The three-dimensional shape of the cerebral cortex -- the wrinkled outer layer of the brain controlling many functions of thinking and sensation -- strongly correlates with ancestral background, researchers have found. The study opens the door to more precise studies of brain anatomy going forward and could eventually lead to more personalized medicine approaches for diagnosing and treating brain diseases.

Principal afferent projections to the motor cortex. Note that the cerebellum and basal ganglia gain entry into the motor and premotor cortices via connections with the ventrolateral and ventral anterior thalamic nuclei. This diagram also illustrates several key corticocortical connections that are essential for motor functions of the cerebral cortex. These include connections from the posterior parietal cortex (areas 5 and 7) to the premotor and supplementary motor cortices, connections from…
Why Brain-Mapping Efforts Matter – Even If They Don’t Succeed | In 1956, a legion of famed scientific minds descended on Dartmouth College to debate one of mankind’s most persistent questions: Is it possible to build a machine that thinks? The researchers had plenty to talk about – biologists and mathematicians had suggested since the 1940s that nerve cells probably served as binary logic gates, much like transistors in computer mainframes.
