Action potential

The sodium-potassium pumps is a plasma membrane transport protein and serve to push an ion into a cell against its concentration gradient. This type of action is known as active transport because it needs the energy to be able to move the ions against their concentration gradient. Generally, the solutes being pushed in or out of a cell will go from a low concentration gradient to a high concentration gradient. The sodium-potassium pump is crucial to kidney function, nerve signaling, and heart…

research prompted Herman von Helmholtz; who stressed a mechanistic attitude supposing a person’s senses performed comparably to machines. He wanted to determine reaction times of neural impulses which were the mechanism that influenced reflexive actions. These three scientists’ research was predicated by the theories of…

Neuroeconomics: the neuroscience of decision making Neuroscience is a scientific field that studies brain activity though changes in brain blood flow. Neuroscience is the discipline in charge of studying through the nervous system activation that occurs in areas of the brain. The body receives information by its interaction with the world and that information gets through our senses, that information is caught from the nervous system and passes through the spinal cord until it arrives to the…

I am Thalamus according Scholapedia, am a small part of the brain located between in the middle and the center of the brain and I’m connected to the cerebral cortex and the midbrain thru nerves. I have many functions, but my main function is to regulate the voluntary motor control, the consciousness whether a person is asleep or awake (the sleep cycle), sight, sound, taste, and touch. I’m composed of 3 different groups of cells; the sensory relay cell or nuclei which receive sensation or…

Selective Serotonin Reuptake Inhibitors (SSRIs) are a class of a drugs that are used to treat psychiatric disorders (Hetirck, et aL. 1). The most common use for SSRIs are for major depressive orders and anxiety. Many Americans commonly use SSRIs to help with moderate to severe symptoms that present in a patient with a mental illness. Due to the beneficial properties found in SSRIs, they are used to treat the brains affected areas, repair nerve damage, and improve overall wellbeing. In simpler…

This essay is about the brain and the growth mindset. Did you know that the brain is the command center for the nervous system? Well yes, the nervous system is part of the brain. There are 100 billion neurons in our brain alone. The brain sends messages via the spinal cord to peripheral nerves throughout the body that serve to control the muscles and internal organs. The largest part of the brain is called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which…

The Central Nervous System is the most important organ system in the human body because it is how we control our body. It consists of the spinal cord, nerve cells, and parts of the brain (Organ System Skit). “The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain” (How Does the Nervous System Work? NCBI). In addition, when the body wants to move, the brain sends a message to the…

About 8 months ago my husband and my life changed. My husband was diagnosis with a disease called Multiple Sclerosis. I have heard of this disease but I never knew what exactly it is. I didn’t know what the symptoms was, the life expectancy, and it was a very foreign matter for both my husband and I. Since we found out I have done tons of research trying to find out everything I can to get some type of knowledge for this. Overview Multiple Sclerosis or M.S. is a chronic disease. This disease…

division, and the interneurons. First, the sensory neuron transmits reactions from the periphery to the central nervous system. In addition it passes on information about the environment such as light or sound. Second, the motor division conducts actions from organs such as muscle and glands…

somatosensory and vestibular terminals. Previous studies in guinea pig and rat have shown that cochlear damage results in a decrease of VGLUT1-labeled puncta and an increase in VGLUT2-labeled puncta. This indicates cross-modal compensation that is of potential importance in somatic tinnitus. In order to confirm this hypothesis, knock-out studies in a mouse model of tinnitus…
