In the following essay I will be looking at both sides of the debate of whether neuroscience replaced psychology in explaining behavior. To begin with we must firstly understand what exactly neuroscience is and what it entails. It is generally defined as the study of how the nervous system develops‚ its structure and the functions it carries out. Neuroscientists study the brain and how it impacts on human beings behavior and cognitive functions. The study also looks at what occurs when things don’t

and support for the nerve cells. Glial cells that are mentioned in this and the following two lectures include: Oligodendrocytes‚ which create the myelin sheaths (electrical insulation) around axons in the central nervous system. Neurolemmocytes (Schwann cells)‚ which create the myelin sheaths around axons in the peripheral nervous system. Astrocytes‚ which control the extracellular environment of nerve cells‚ for example by removing “used” neurotransmitter molecules. The nerve cell membrane

molecules are free base and 50 % of the molecules have a positive charge - ionised).If bicarbonate is added to levobupivacaine‚ the pH is increased leading to a rise in the percentage of free base molecules. Those molecules cross more easily through the axon membrane and the pharmacological action begins more quickly.In contrast‚ if the pH is low (acid)‚ as happens when there is a local infection‚ there will be less

Dendrites extend from the cell‚ as do axons. Dendrites receive any incoming input while axons release signals out of the neuron. 2.

Cells are the structural and functional units of all living organisms; each specialised to perform dedicated duties throughout their life span. All living organisms can be sorted into one of two groups depending on the fundamental structure of their cells. These two groups are the prokaryotes and the eukaryotes. A Prokaryote cell is the first form of cells for many millions of years until the eukaryote cell evolved from the prokaryote cell‚ which created life. Prokaryote cells are organisms made
