The effects of electrical and chemical stimulation take place within different places in the brain that selectively affect specific psychological processes as well as psychologically active medications; anesthetics and recreational drugs). These selectively affect different mental processes because they act on the brain in different

Some scientists and philosophers believe that the mind and the brain are one‚ in the sense that the brain controls the mind; however‚ this idea is quite debatable. It is extremely difficult for us to fully understand the mind versus the brain in terms of their respective functions. “Many aspects of cognition will never be explained through a scientific

article “Secrets of The Brain” by Carl Zimmer was published in National Geographic. I am grateful I chose to study this article about the brain because it is simply mind blowing. Our brain is far more complicated then we put it out to be. Our knowledge is extremely limited and there is much work to do. Carl Zimmer lays out some of the knowledge that we do have about the brain but he mostly covered what we do not know and what scientists are working to understand. We as humans did not even begin to

Effects of Bacterial Meningitis on the Brain Abstract Meningitis is an infection of the subarachnoid space (located between the middle arachnid matter and the inner pia mater) of the meninges‚ which is the thin layer of tissues that line the brain and the spinal cord. Cerebrospinal fluid flows through the subarachnoid space and the meninges‚ providing cushion for the brain and the spinal cord‚ and filling the internal spaces within the brain. There are 2 main types of meningitis

the years scientists have discovered that there is more to the brain than previously thought. They have learned that inside the brain there is a synapse or an area that is open between the axon of a nerve and the dendrite of another nerve. The synapse entails the neurotransmitters‚ mitochondria‚ postsynaptic ending that has receptors sites for the neurotransmitters‚ and a synaptic cleft. When alcohol is consumed and reaches the brain‚ it can alter neuron membranes‚ ion channels‚ enzymes‚ and receptors

project I was attempting to test brain dominance in gender. I had people take the same brain dominance test to see if the individual thought with more with the left side of the brain or the right. In my experiment I had 59 people take the same questionnaire to see which hemisphere of the brain was more dominant as a whole. I became intrigue on the topic of brain dominance after doing some research on the brain. The brain is a very complex organ one hemisphere of the brain corresponds with the opposite

Medulla A structure of the brain stem that is responsible for automatic bodily functions‚ such as breathing and heart rate. 3. Reticular Activating System The RAS screens incoming information and arouses the cortex when something happens that requires their attention. 4.
