brains continue to generate new neurons well past when was originally thought. This process is called neurogenesis‚ and until recently‚ was seen as a development only occurring in embryonic and perinatal stages in mammals. Luckily‚ this continues throughout life‚ and is beneficial to college students in multiple ways! Similar to progenitor cells in the developing brain‚ the adult brain contains a small number of stem cells that are able to divide and produce neurons. Through research conducted involving

underlying spatial behaviour could therefore help to understand such cognitive decline. An important contribution to this endeavour was the discovery of spatially modulated place and grid cells (Kiehn & Forssberg‚ 2014). Hippocampal place cells are neurons that fire whenever an animal is located in a particular region in the environment (Moser & Moser‚ 2008). These place cells remain to fire in a novel environment‚

Alzheimer’s disease is characterized as a type of dementia that causes problems with memory‚ thinking‚ and behavior. It is irreversible and it slowly destroys memory and thinking skills and‚ eventually‚ the ability to perform simple tasks. Unfortunately‚ Alzheimer’s is the sixth leading cause of death in the United States and over five million Americans are currently living with Alzheimer’s. There are many symptoms within each category of Alzheimer’s. In mild Alzheimer’s disease‚ where Alzheimer’s

system. These chemical messengers‚ called neurotransmitters‚ are released and received by the brain’s many nerve cells‚ which are also called neurons. Neurons are constantly communicating with each other by way of exchanging neurotransmitters. This communication system is essential to all of the brain’s functions. A tiny space called a synapse connects neurons to one another. Depression has been linked to problems or imbalances in the brain with regard to the neurotransmitters serotonin‚ norepinephrine

if you’re learning a new skill you constantly have to think about it because you’re not used to it. Doing this can make you think and process information fast by strengthening your synapses. Thoughts are electrical impulses that travel from neuron to neuron through a synapse. It’s basically just transmits information‚ so the stronger the synapse the easier the brain and can transmit thought. I find it no surprise that nicotine improves a person’s focus. It is a mild stimulant which increases dopamine

Dendrites: the receiving part of the nucleus 2. Cell body (Soma): The processing part Electrochemical Transmission 3. Axon: the transmitting part Normal habit change: Doing the same behavior over and over again (same neurons being used over and over) Nerve: a bundle of neurons that have a specific purpose Transmission

exercises on the body’s nervous system‚ Sir Charles Sherrington became a great contributor to Neurophysiology in its early stages of study. His work on the brain’s neuron processes unveiled how certain areas of the brain relate and work with each other to endorse the process of learning‚ the unearthing of “the anatomical concepts of the neuron and synapse” (Eccles‚ J.‚ 1957‚ p 218). Sherrington’s achievements led to new advances in the field of neurophysiology. Without the
