Essays on Neural Activity

Summary

The neural network controls physical activities. Recently scientists have found out that the neural network can be observed to show different levels of activation depending on an organism’s mental activity. Scientists have gone further to devise actual methods that detect brain activity in particular instances. The brain and the neural network never stop working; however, certain tasks cause the brain and the neural network to work faster, harder and more intensely (Garcia). These unique activities usually register or appear as spikes or dips in the never-ending sequence of brain activity. Genetically Encoded Voltage Indicators (GEVIs) are a promising ...

Abstract

The present article discusses the anatomical and functional aspects of human memory. Memory is an integral part of our cognitive processes and gives the meaning to life. The importance of memory can be ascertained by studying the conditions associated with memory loss. Scientists have established the ‘what,’ ‘where’ and ‘how’ of the memory by using animal models or the modern computerized techniques like CT, MRI and PET. The medial temporal lobes of the hippocampal region are the primary sites of memory and learning. However, the final storage site of memory is presumed to be neo-cortex. Depending on the anatomical ...

Caffeine is a compound that has a molecular formula of C8H10N4O2 and is commonly known as methylxanthine [1]. The systemic name of caffeine is either 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione or 1,3,7-trimethyl xanthine. Other names that are used to refer to caffeine include mateine, theine, coffeine, and guaranine. It is a chiral molecule and has no stereoisomers. The caffeine compound has two groups of amide that predominantly exist as zwitterionic resonance structures. In these structures, the atoms of nitrogen and carbon are bonded through a double bond to one another making the two nitrogen atoms are basically planar. This results in a ...
