Q:

What are the effects of lack of oxygen to the brain?

A:

New York University states that the effects of a lack of oxygen to the brain depend on severity but include difficulty paying attention, poor judgement, poor coordination, intense emotions and drowsiness. In more severe cases, the effects include seizures, loss of consciousness and difficulty breathing. If the brain goes without oxygen for more than four minutes, brain cells begin to die, and a further lack of oxygen can lead to death.

According to New York University, many conditions can lead to a lack of oxygen to the brain. Any failure of the respiratory system, whether due to injury, toxins (such as carbon monoxide), drowning or smoke inhalation can reduce the amount of oxygen entering the blood and thus reaching the brain. Disruptions to blood flow, including the blockage or rupture of blood vessels or cardiac arrest can also keep oxygen from reaching to the brain.

New York University states that diagnosis of a lack of oxygen to the brain involves a number of different tests, but the most important factor is medical history. Tests include physical exams and blood analysis. If necessary, imaging scans of the cardiac or respiratory systems also occur. Monitoring of the activity of the heart or brain via electrocardiogram and electroencaphalogram can also be helpful. Treatments must focus on both the immediate lack of oxygen and the underlying conditions.

    What happens when the brain is deprived of oxygen?

    A:

    The New York University Langone Medical Center explains that brain cells begin to die after about four minutes without oxygen. Brain damage caused from a lack of oxygen is called anoxic damage, while hypoxia describes a low-oxygen condition. In other words, someone suffering from a lack of oxygen is said to be hypoxic, but any damage sustained is anoxic damage.

    What cells line the ventricles of the brain?

    A:

    Ependymal cells line the ventricles of the brain and the central canal of the spinal cord. The cells also form the choroid plexus, a network of blood vessel cells in the walls of the two largest ventricles, the lateral ventricles.

    What is interesting about Albert Einstein's brain?

    A:

    Albert Einstein's brain was cut into 240 pieces after his death in 1955, and scientists determined that the physicist's parietal lobe was 15 percent larger than normal, and that part of his brain was missing the Sylvian fissure. The parietal lobe deals with spatial, mathematical and three-dimensional abilities. A missing Sylvian fissure allows brain cells to communicate faster in the parietal lobe.

    What is the function of association neurons?

    A:

    The Free Dictionary explains that an association neuron is a neuron found in the brain and spinal cord that conducts impulses between neurons. These neurons are commonly referred to as internuncial neurons or interneurons. According to Wikipedia, an interneuron is a neuron that forms connection between other neurons.
