You need to know where the major lobes are located and what each lobe does in terms of function (see below for functional descriptions) Here we see the interior of the brain. If you were designing a brain you would want the Sensory areas right next to the Motor areas so that an organism could react very quickly to an incoming stimulus (like a baseball flying towards your head)

Cerebellum Functions: Movement Balance Posture The word "cerebellum" is derived from the Latin word for "little brain." Located behind the brain stem, the cerebellum is similar to the cerebral cortex because it has hemispheres and a cortex that surrounds the hemispheres. (Requires the FLASH plug-in for your browser.) Did you know? John Adams (2nd President of the US) and his son, John Quincy Adams (6th President of the US), were both born in Braintree, Massachusetts
The Thalamus and Cerebral Cortex (Integrative Systems) Part 2
Thermal signals are then transmitted to the postcentral gyrus, but the sites where these fibers are distributed do not appear to be localized to any one area of the postcentral gyrus. The outputs of the lateral dorsal nucleus have been shown to project to several regions of the limbic system, including the cingulate cortex, and to the medial wall of the posterior parietal cortex
Temporal Lobe - Areas of the Brain
The location of the temporal lobe is highlighted in yellow in the image at the right.The temporal lobe is associated with a number of different functions, including auditory perception, long-term memory and emotional responses.

BRAIN AREAS SUPPORTING CEREBRAL CORTEX FUNCTION
By contrast, there is one climbing fiber for about ten Purkinje cells, and every single action potential in a climbing fiber will cause all ten (or so) Purkinje cells to fire. Patients with carbon monoxide damage to the globus pallidus and putamen show a loss of initiative and a tendency to engage in repetitive activities, even when there is no evident loss of intellectual capacity

The Cerebral Cortex
The laminae vary in thickness from one area of the cortex to another, and specific columns are involved in very precise activities (for example, responding to a specific pattern of light or a specific kind of touch). For example, if you are looking at something (and this would involve the occipital lobe), the parietal lobe would give you information about which direction your eyes are pointing, the position of your head, and the tilt of your body as you viewed the object
THE ACTIVATION SEQUENCE FOR THE MOTOR AREAS The information processing that the brain must perform to initiate a voluntary movement can be divided into three steps. When this comparison does not allow the expected result to be achieved satisfactorily, the cerebellum's activity modifies the sequence of movements in a compensatory manner to make them more effective
Role of motor cortex NMDA receptors in learning-dependent synaptic plasticity of behaving mice : Nature Communications : Nature Publishing Group
With an improved genetic mouse model, a recent study provides the best evidence thus far that the NMDAR in the dorsal CA1 subfield and dentate gyrus is not required for the acquisition of spatial memories, despite impaired hippocampal LTP in these mice52. Control mice (Cont-vMCx) acquired the classical conditioning test with a progressive increase in the percentage of CRs, reaching asymptotic values by the 7th conditioning session (Fig
The Island of Reil or Insula is a cortical area which lies below the fissure of Sylvius and is considered by some anatomists to be the fifth lobe of the cerebrum. Brodmann's Classification System Studies done by Brodmann in the early part of the twentieth century generated a map of the cortex covering the lobes of each hemisphere
axons innervating some somatic motor nerve cranial nuclei decussate before their termination and so control contralateral muscles; corticobulbar tracts controlling other motor nuclei split, some axons decussating and others descending ipsilateral, resulting in bilateral innervation c. Organization: somatotopic: small, distorted, discontinuous map of the body (homunculus), with larger areas devoted to body regions characterized by fine or complex movements and smaller areas to body regions characterized by gross movements involving few muscles 4
It lies parallel to two main neural pathways: one that carries sensory messages to the part of the brain that analyzes them, and another that emerges from the cortex and descends to the muscles to make them contract. To carry out goal-directed movements, your motor cortex must first receive various kinds of information from the various lobes of the brain: information about the body's position in space, from the the parietal lobe; about the goal to be attained and an appropriate strategy for attaining it, from the anterior portion of the frontal lobe; about memories of past strategies, from the temporal lobe; and so on
What is the Motor Cortex? (with pictures)
The motor cortex is divided into regions that represent the regions of the body, and neurons in each region correspond with the movements in the related part of the body. by email wiseGEEK Slideshows Top 10 amazing movie makeup transformations 10 most extreme places on Earth Top 10 facts about the world These 10 animal facts will amaze you These 10 facts about space will blow your mind Adorable animal families that will make you "aww" Top 10 unbelievable historical concurrencies Can you see through these real-life optical illusions? 10 hilariously insightful foreign words You won't believe these 10 facts about people The motor cortex of the brain is a region in the posterior part of the frontal lobe that controls voluntary movement
Thus, rather than firing as the result of muscle activity, these neurons are involved in relaying motor commands to the alpha motor neurons that eventually cause the appropriate muscles to contract. Thus, the premotor cortex and supplementary motor areas appear to be higher level areas that encode complex patterns of motor output and that select appropriate motor plans to achieve desired end results
