a) How has thinking about the “mind-body” relationship changed within the context of history?
Plato hypothesized that only death could separate the soul from the body while Aristotle identified the soul as a property of the body (Pinel, 2009). Rene Descartes believed that the mind controlled the brain while Huxley postulated that the mind was a product of the human brain.
b) Why might it be important and suggested to study the relevant history prior to studying a subject of "mind/body"?
It is important to study the relevant history prior to studying a subject of "mind/body" in order to know the type of ...view middle of the document...
c) How does the study of behavioral genetics gather data? (Give at least two (2) examples)
Behavioral genetics gather data through the reductionist approach and by utilizing approved functions of the brain and neurotransmitter systems (Schroeder, 2007).
a) What is/are a mutation(s) and what are some possible ways that this can occur?
Mutation refers to the undeviating transformation of the nucleotide succession of a genome in a DNA, virus, and organisms (Harter, 2003). Mutation can happen as a result of DNA copying flaws during cell division, ionizing radiation exposure, and virus infection
b) Give one (1) example of how a mutation may not be beneficial for an organism’s survival.
Mutation can be ineffective to an organism survival if it causes diseases like atherosclerosis caused by contemporary lifestyles and diets.
c) Give one (1) example of how a mutation may be beneficial for an organism’s survival.
Mutation may be beneficial when used in drugs targeting specified bacteria, such as HIV
a) Define the “Neuron Doctrine” and briefly Ramon y Cajal’s contributed to this field
Neuron Doctrine is a concept stating that the nervous system comprises of distinct individual cells (Francisco, Jesús, and Alamo, 2006). Cajal contributed to Neuron Doctrine by providing detailed accounts of types of cells linked to neural structures and their connectivity.
b) Describe the parts of the Neuron.
The neuron has three parts; the soma, the dendrites, and the axon. The soma is the body of the nucleus cell; the dendrite receives messages; while the axon sends them.
c) Describe the process of firing a neuron; include the All-or-None Principle and Absolute Threshold.
Neuron firing or activation occurs when a chemical information, heat, pressure, or light stimulate the neuron from new cells. The process occurs through the all or none principle that states that the action potential maintains the axon’s length without decreasing because the action potential relies on the characteristic of a cell rather than the triggering stimulus’s strength when the neuron is triggered. However, the absolute threshold maintains that the neuron fails to fire again even when the stimulation is great.
a) Describe the process of chemical communication between neurons; include how neurotransmitters are made, travel, are released, what they do, and how...
