The stroke syndromes. most common is middle cerebral artery. Key Loc=loss of consciousness Bulb= memory Spiral= confusion These are intact in MCA..only in ACA memory is affected hence the bulb is crossed out. Divide the body in 4 boxes representing upper and lower limbs and each box is further divided into S (sensory) M (Motor). The dark shading means this is affected more. Dotted shading means affected to a lesser extent. Note how sensory is intact (not shaded) in webers and benedict . The red dot in brain = site of infarction The 2 circles represent visual field. ( intact in ACA). Only ACA has urinary incontinence (shown by leaking urine) Note. For Benedict. .Ataxia is shown by shading under the legs on one side (although legs are represented by boxes the stick lines as legs is only used to represent ataxia). tip..whenever faced with an infarct question draw the man and symbols shown and shade accordingly. Will definitely help diagnose the case quickly.

An edited version of my Friday Evening Discouse given to the Royal Institution on 11 April 2008. Abstract: The vagus nerves (cranial nerve X) connects our brainstem to the body, facilitating monitoring and control of many automatic functions; the vagus electrically links our gut, lungs and heart to the base of the brain in an evolutionarily-ancient circuit, similar between mammals and also seen in birds, reptiles, and amphibians. The vagus comprises a major part of the parasympathetic autonomic nervous system, contributing to the motor control of important physiological functions such as heart rate and gut motility. The vagus is also sensory, relaying protective visceral information leading to reflexes like cough and indication of lung volume. The vagus has been described as a neural component of the immune reflex. By monitoring changes in the level of control exerted by the vagus, apparent as beat by beat changes of heart rate, it is possible to indirectly view the effect of pharmaceuticals and disease on brainstem function and neural processes underlying consciousness. The paired vagus nerves of humans have different functions, and stimulation of the left vagus has been shown to be a therapeutic treatment for epilepsy, and may modulate the perception of pain.

Can you imagine being able to search for locations in the human body in the same way you can on Google Maps? This thinking lead Programmer Rich Stoner to create this amazing video of a 21st Century Map of the Brain which was our most popular tweet last week. A 21st Century Map of the Brain http://t.co/tkojzJBW55 via @brianglanz #openscience— Meducation (@Meducation) October 18, 2013 Rich writes in his blog - “Now we can quickly search Google Maps for a location, ask what is nearby, and even see what it looks like using StreetView. Now, imagine if something like that existed for the human brain: an interactive environment to search, visualize, and explore layers upon layers of neuroanatomy. This is the dream of cortical cartographers (also known as neuroanatomists). 10 years ago, one of the largest brain mapping initiatives was founded by Paul Allen with a single goal: to build a 21st Century Map of the Brain.” Click here to read more. The mapping of the brain is a working progress and therefore not 100% accurate. Even so the video gives us an insight into the innovate ways we will be able to interact with science in the future.
