The Human Brain · Atlas of the Human Brain · Brain in Stereotaxic Space Brain – The Atlas of the Human Brain in Stereotaxic Space A short introduction in to the Atlas of the Human Brain and the Brain used throughout for the research on this site. To take a more systematical approach to the use of the provided material both on the DVD from the "Atlas of the Human Brain" and the applications you can find on this website the following explanatory steps might help. Figure 1: The Brain used for research in the "Atlas of the Human Brain" and which are used for the main applications is from a 24-year-old male from the Vogt collection in Düsseldorf. Further details about The Brain.
Nuts and Bolts the neuron A single neuron may be connected to as many as 200 000 others, via junctions called synapses. They form an extensive network throughout the body, and can transmit signals at speeds of 100 metres per second. This enables animals to process and respond to events rapidly, for example by carrying sensory information from the ears to the brain, then instructions for movement from the brain to the leg muscles Within a neuron, signals are transmitted by a change of membrane voltage – a variation in the difference in electrical charge between the inside and outside of the cell.

Brain Structures and Their Functions The nervous system is your body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test. Nerves reach from your brain to your face, ears, eyes, nose, and spinal cord... and from the spinal cord to the rest of your body.
Breath Sounds Lung sounds Breath Sounds Auscultation of lungs help determine the airway and alveolar integrity, ventilation and presence of abnormality. There are two normal breath sounds. Human brain The human brain has the same general structure as the brains of other mammals, but has a more developed cortex than any other. Large animals such as whales and elephants have larger brains in absolute terms, but when measured using the encephalization quotient which compensates for body size, the human brain is almost twice as large as the brain of the bottlenose dolphin, and three times as large as the brain of a chimpanzee. Much of the expansion comes from the part of the brain called the cerebral cortex, especially the frontal lobes, which are associated with executive functions such as self-control, planning, reasoning, and abstract thought. The portion of the cerebral cortex devoted to vision is also greatly enlarged in humans.

Neuron Conversations: How Brain Cells Communicate Nerve impulses involve the opening and closing of ion channels. These are selectively permeable, water-filled molecular tunnels that pass through the cell membrane and allow ions — electrically charged atoms — or small molecules to enter or leave the cell. The flow of ions creates an electrical current that produces tiny voltage changes across the neuron’s cell membrane. The ability of a neuron to generate an electrical impulse depends on a difference in charge between the inside and outside of the cell. When a nerve impulse begins, a dramatic reversal in the electrical potential occurs on the cell’s membrane, as the neuron switches from an internal negative charge to a positive charge state. The change, called an action potential, then passes along the axon’s membrane at speeds up to several hundred miles per hour.
