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.Know More
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.Learn more about Nerves
Reading enhances connectivity in the brain, improves brain function and also improves theory of mind — the understanding that people may have beliefs and values different from the reader's own. A study conducted at Emory University and published in the journal "Brain Connectivity" first detailed some of these positive effects on the brain.Full Answer >
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.Full Answer >
The central nervous system, composed of the brain, spinal cord and an extensive neuron network, serves as the control center for all bodily functions. It functions as the transmitter and receiver as well as the pathway for information flow and determines how the body responds to changes in its internal and external environment.Full Answer >
The brain stem, thalamus and cerebral cortex are the three structures of the brain that receive and process sensations of pain, according to BrainFacts.org. Different parts of the cerebral cortex are involved with painful sensations originating from specific parts of the body. Pain processing occurs in the sensory cortex.Full Answer >
