Take a "Course" How does our brain work
	Different parts of our brain control different parts of our body. One part is in charge of understanding what the eyes see; another part directs speech; a different part controls hearing; still another exercises reason. The left side of the brain controls movement on the right side of the body and receives sensation from the right side of the body, and vice versa. Evidence suggests that the brains' left hemisphere tends to deal with reasoning and communication and the right hemisphere with emotions and perception of shapes. All the parts of the brain do their work and talk to each other over a network of nerve cells called neurons and nerve fibres  Sensory Cortex. Seizures arising from here may cause the tingling of an arm, leg, face, or side of body. The brain works on electricity. The normal brain is constantly generating electrical rhythms in an orderly way. Millions of tiny electrical charges pass between a network of nerve cells in the brain and to all parts of the body via chemical messengers called neurotransmitters, which cause the nerve cells to fire or stop firing. In simple terms, the nerve cells, called neurons, are the brain's telephone system, sending electric charges from one point to another. Normal human experiences occur when specialized parts of the brain responsible for taste, smell, movement, memory etc. are sufficiently excited. This is how we think, feel and move. Move your finger now. When you do so, muscle fibres on each side of your finger joint are involved. Different groups of brain cells control the different muscle fibres, and their coordinated firing is what allows you to manipulate your finger smoothly. [Back] Auditory Area (Hearing) Seizures in which one hears unusual sounds or music may arise from this area of the brain. Autonomic (Underneath Cortex; Controls Involuntary Bodily Functions) Autonomic seizures involve a strange feeling in the abdomen, a rapid heartbeat, sweating or goose bumps, and/or the face becoming pale or flushed. Broca's Area (Controls Speech) Seizures coming from this area temporarily stop the production of speech. Frontal Lobe (Controls Judgement) Seizures coming from here may produce temporarily impaired judgement or disruptive behaviours. Mesial (Inner) Temporal Lobe/Limbic Cortex (Emotions) Seizures in which one smells an unpleasant odour, feels fear or an intense mood swing or experiences a strange memory (dŽjˆ vu) or sense of unfamiliarity or a dreamy unreality may come from here. Motor Cortex (Controls Movement) Seizures coming from here may cause an arm or leg to jerk, the face to grimace, etc. Occipital Lobe (Visual System) Seizures in which one sees flashes of light or visual distortions arise from here. Sensory Cortex (Sensations) Seizures arising from here may cause the tingling of an arm, leg, face or side of body. Supplementary Motor Area (Coorinates Movement) When a seizure arises from this area of the brain, the eyes, head and body may temporarily turn to the opposite side. Temporal Lobe (Psychomotor) Temporal lobe seizures often involve chewing movements, wetting lips, and other "automatic" movements (like picking at clothing), with staring and loss of awareness. Wernicke's Area (Language) Seizures in this area may produce a temporary inability to understand language.
