Nucleus accumbens

The nucleus accumbens is the release sight for the neurotransmitter dopamine, a nature chemical in the central nervous system. When released in standard quantities, it assists in critical brain functions. Like most neurotransmitters, dopaminergic signaling entails an equilibrium between dopamine release and the re-uptake by presynaptic nerve terminal. Under specific circumstances, a stimulus will promote the release of dopamine into the synapse. Dopamine transporters will then remove the dopamine from the synapse so that vesicular monoamine transporters can store the neurotransmitter into vesicles, release it, and protect it from oxidation (Riddle et al, 2006). Damages in dopamine transporters or the vesicular monoamine transporters will cause…

the fairness. In the U.S. when an even split was made, the partner would always accept, but when it was anything less than half, the partner almost always denied it. They would rather refuse the money all together than have the splitter benefit unfairly. Contrarily, the Machiguenga tribe accepted any amount of valuables no matter how unfair the split was. The majority of splits were an 85 to 15 percentile, favoring the splitter. But the Machiguenga partner had a mind set that “any amount of…

I drew a boiling pot of water to represent the importance of water. Water is important for many causes. Water is transported through cells by osmosis. Osmosis is the diffusion of water across a selectively permeable membrane. Water moves through cells by passive transport, facilitated diffusion, or active transport. Water moves from low solute to high solute. Water is important for cells and organisms. I drew a prokaryote to represent the different types of cells. Prokaryotes are the simplest…

Overall Impact Numerical Score: 3 Overall Evaluation: This is a competitive renewal application on Poultry Dust and Lung Inflammation form an established investigator. The renewal application builds on the discoveries made in the last funding cycle on effects of poultry dust on lung epithelial cells and monocytic cells, and lung inflammation in a mouse model. The data showed that poultry dust contains protease activity,…

There are two overarching classes to these organisms: prokaryotes and eukaryotes (Reece et al., 2014). Prokaryotes (meaning before nucleus) are put in two domains: Bacteria and Archea (Biology Department, 2015). Eukaryotes on the other hand, (which have nuclei), are in the Eukarya domain and encompass all other organisms such as plants, animals, fungi and protists (Biology Department, 2015). The most effective way to distinguish between classes comes from observations made about their structure.…

According to Solso (2008), artificial intelligence is a branch of computer science that uses programs to enhance cognitive functions. Pattern-recognition uses previous experience to identify a pattern accurately. Pattern-recognition through artificial intelligence is an area being explored at an extraordinary rate. Through the use of experiments using mouse brains and three data sets that consider neural networking for pattern recognition is not so far away. In the study presented by Zeng…

Eukaryotic Cell Organelles What are eukaryotic and prokaryotic cells? Organelles in Eukaryotic Cells The Nucleus. Nearly all animal cells have a nucleus, with the only exception being the red blood cell. The nucleus has two major functions, which are housing the DNA and controlling the cell’s activities. In the centre of the nucleus is the nucleolus. This doesn’t have a membrane, but holds itself together. In the nucleolus, ribosomes are created through the mixture of RNA and proteins.…

contain a nucleus and have membrane bound organelles they are multicellular cells and undertake reproduction by the process cell division known as meiosis and mitosis. There are 2 types of eukaryotic cell: plant and animal cells. They contain organelles such ribosomes, smooth and rough endoplasmic reticulum, mitochondria, nucleolus, centrioles, cell membrane, flagella, cilia, microtubules, chloroplast and lysosomes. Animal Cell: …

Technology today now allows us to address the idea of cloning. Cloning is creating an identical genetic copy of an organism or a cell. The process of this is there will be three subjects A, B, and C a body cell will be taken from A, the DNA will be extracted then an egg cell will be taken from B the nucleus removed. The DNA from A is fuse with the egg cell from B the fused cell develops into an embryo when it is placed in C the surrogate and then the clone is of subject A. To get to cloning…

The human genome is composed of millions of molecules of DNA perfectly packaged into 23 chromosomes. Each human is the result of a combination of the same four nucleotides, yet every single one is unique. Perhaps, this is due to the slight variation in each human’s DNA, or maybe the explanation lies in a person’s upbringing. The purpose of studying human development is to understand why people change by applying the scientific method to existing theories, which provide the basis for…
