Plasticity and neurotransmitters are terms that I expect to remember in five years not only because they are very useful terms, but they are intriguing and captivating subjects. Plasticity is the brain’s ability to modify itself after something such as an injury. The highest plasticity occurs during childhood. Once someone reaches the age of ten the pathways in our brain start to become hardwired and the pathways we don’t use disappear. Once the pathways are hardwired into our brain the ability for
EFFECT OF EMOTION ON MEMORY How emotion affects memory. According to (Purves et al., 2001), Emotions pertain to subjective feelings and their associated physiological states and can therefore have dominant impact on memory. This means that emotion plays significant role in the four distinct but related types of memory processing i.e. encoding, consolidation, storage and retrieval. Encoding is the first critical step to creating a new memory that begins with perception through the senses. Many studies
nervous system can affect behaviour: the nervous system consists of the Central Nervous System (CNS) - the brain and the spinal cord - as well as the peripheral nervous system (the nerves which carry electrical signals to and from the CNS). These nerve cells are adapted to transfer electric signals through dendrites, axons, synaptic terminals, and most importantly, neurotransmitters. Neurotransmitters are chemicals which are released from the cross synaptic cleft and bind to receptors on another neuron
functions, especially the brain, as it is the hub of all bodily actions. The Human Brain is the core of the nervous system, it is made up of millions of nerve cells. The Brain allows us to think, talk, respond, create, and much more. So, how do drugs affect the way it functions? Many drugs have different effects on the brain, in different areas. Firstly, Cocaine: Cocaine is a drug that has its greatest effect on the cerebral cortex and the limbic system. Normally, a neurotransmitter called dopamine is
How our brain works Depression and schizophrenia are two of the many mental illnesses that a physician can treat with effective medications. Knowing how medications work can increase your understanding of mental illness and encourage compliance—that is, consistently sticking to your medication treatment plan so that the medications are given a chance to be effective. This article will explain how antidepressant and antipsychotic medications work in the brain to treat these disorders
depressed shows signs of: irritability, less activity, less attentiveness and fewer facial expressions. The effect of depression that impacts the brain, heart and other parts of the body is considered a physical effect. It is known that depression affects the brain in a negative way. One of the most disturbing effects of depression is a decrease in the brain volume. Other physical effects that depression has is: decreased interest in sex, decreased appetite, fatigue, insomnia or oversleeping.
Multiple Sclerosis is a disease that directly effects the central nervous system, more particularly the brain and spinal cord. Typically in people who suffer from Multiple Sclerosis (MS), there is a depreciation in the myelin sheath, which is a protective insulating layer covering the axon of neurons. This sheath increases the rate of which neurotransmitters are transferred along axons. With MS, the myelin is targeted by the immune system, causing deterioration. The immune system see’s the myelin
Aniracetam vs Piracetam - benefits and side effects Being called as ‘Smarty Pants’ always gives us a kick, doesn’t it? We live in a world where being one of the best is all that matters. With mounting pressure from family, peer, management and all others alike, the need to perform extraordinarily well is what we all are looking at. To our relief science has come up with a most effective solution to this pressing issue. Racetams are a type of nootropic cognitive enhancing drug. Racetams are well
mmol/kgww, while PE is approximately 1.4 mmol/kgww. Glucose (Glc) acts as a major source of energy in the brain. Its concentration is around 1 mmol/kgww. The spectrum of a Glc comprise of multiple spectral patterns. Glutamate (Glu) is most abundant amino acid found in human brain that consists of a side chain. Glu has a value of 12 mmol/kgww. It is considered as an excitatory neurotransmitter. Since glutamate comprise of two methylene groups and a methine group. Consequently, it has a complex spectrum
schedule three, scientists could learn a lot about the neurochemistry and neurophysiology of what these psychedelics can offer. Legalization and prohibition each have pros and cons. However, restricting and banning research into the benefits and side effects of psychedelics is naive. If the use of certain psychedelics in a controlled environment, administered by a certified clinician allows one to overcome depression, PTSD, anxiety or relieve someone of pain suffering from terminal cancer, it is a disservice
