Aspartate and glutamate act as neurotransmitters in the brain by facilitating the transmission of information from neuron to neuron. Too much aspartate or glutamate in the brain kills certain neurons by allowing the influx of too much calcium into the cells. This influx triggers excessive amounts of free radicals, which kill the cells. The neural cell damage that can be caused by excessive aspartate and glutamate is why they are referred to as "excitotoxins." They "excite" or stimulate the neural

The essay I chose to summarize is, “The Man Who Mistook His Wife for a Hat.” In the story, author ,Oliver Sacks focuses on a man who has loss of brain function in certain areas. Sacks is a professor in neurology and has shared some stories of some of his most iconic patient experiences. Sadly, it focuses on a man named Dr. P who suffers behavioral consequences . The human brain is so unbelievably complex, it has the ability to control all we do. This story not only compels its readers to dive

structure that is located in the middle of the brain. It has broad nerve connections between the cerebral cortex and midbrain (Mandal, 2014). It surrounds the third ventricle in the brain. The thalamus has several functions in the brain. It relays information in the brain by detecting, processing and relaying information from the various body senses, except smell, to the appropriate locations in the cerebral cortex. The thalamus has the function of regulating consciousness and stages of sleep. Moreover

The brain is the central part of central nervous system in all animals. It is composed a many different subunits that work together to help the animal function properly. An important part is the cerebrum, which is “responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in the body.” This is composed of the four lobes, the frontal, parietal, occipital, and temporal lobes. The frontal lobes are involved in moving and thinking

Assessment of the Retrosplenial Cortex in Head Direction cell Landmark Acquisition and Maintenance Key Words: Head Direction Cells, visual integration, retrosplenial cortex, episodic memory BACKGROUND: Spatial navigation serves as the foundation of episodic memory. Without navigational memory, locating the nearest grocery store, your home or even an object in your home could prove debilitating. Spatial navigation is a trait found in primates and most mobile animals, making this a worthwhile topic

Running head: WHAT THE BRAIN IS ABLE TO DO? Brain Concentration Brittany Mangum Chemistry 2nd period 9-30-12 Abstract It's important to understand the complexity of the human brain. The human brain weighs only three pounds but is estimated to have about 100 billion cells. The brain is divided in half, a right and left hemisphere. The right hemisphere deals more with visual activities and plays a role in putting things together. The left hemisphere tends to be the
